The story begins in Japan, where more than 200,000 powerful ninjas exist. They appear to be ordinary people, but in reality, they live extremely dangerous lives. Suzuki is a low-level ninja who blends into [music] normal society while working as a magazine editor.

One day, she suddenly receives a secret message. She quickly says goodbye to a writer and rushes toward a bridge. [music] When she arrives, she notices a Russian man known for hunting ninjas. She has been assigned a mission to eliminate him.

The man opens fire on Suzuki, but she swiftly dodges the bullets. She counterattacks by striking him [music] with her heel, which instantly transforms into two sharp daggers. The man narrowly avoids the attack and continues shooting at her. Suzuki dodges again and throws several ninja stars at him. She then closes the distance [music] and kicks his jewelry.

Despite her efforts, the man remains unstoppable. Even Suzuki's electric baton fails to affect him [music] and he knocks her to the ground.

Another ninja observes the fight from a distance. His name is K.T.O, a high-ranking ninja. He is about to shoot the man when at that moment a toothpick pierces his arm. As he turns around, he sees a young man running toward him. This young man is also a ninja named Kuro. Kuro easily overpowers the Russian man [music] and finishes him off with a chokeold. Afterward, he tells Suzuki that he is leaving and that she can handle the rest. [music] Suzuki is left in shock. She wonders what kind of man would walk away and let someone else take credit

for his actions. Kuro calmly replies that he does not want to do too much work and just wants to go [music] home and sleep. Although Kuro is highly skilled, he is also extremely lazy.

He quietly leaves the scene. Kuro lives alone in an old and cheap [music] house. When he feels bored at home, he practices blowing a toothpick hard enough to use it like an arrow. Suddenly, someone silently enters his room. [music] It is his senior Ko who has come to assign him a mission.

After World War 2, a group of rogue ninjas formed a dangerous organization known as the Underground Ninjas. Based on intelligence reports, they have infiltrated and taken control of Zone High School. The school is located in a special area where the abandoned Natano Military School once stood. Secrets from the war are believed to still be hidden there. Kuro's mission is to go undercover and uncover the group's true [music] plans.

To assist him, Ko provides Kuro with a special suit. This suit allows him to disappear, [music] but only on the surface level.

While testing the suit and trying to kill time, Kuro hears one of his friends calling out for toilet paper. The toilet paper [music] is placed far away from the seat. She warns Kuro that if he looks at her, she will beat him up. Following her instructions, Kuro climbs along the wall and avoids her gaze.

He carefully [music] reaches the toilet paper. However, when he turns to hand it to her, he ends up getting slapped in the [music] face. The next morning, Kuro arrives at Judend High School.

When he learns that he must take an entrance exam, he [music] becomes extremely anxious. For a moment, he thinks that none of it is worth the trouble. He decides that he should just complete the mission and leave.

But then the fear of Kato begins to haunt him. Kuro starts wondering how he can possibly [music] pass the entrance exam. With his tired yet handsome face, Kuro quickly catches the attention of Nguchi, [music] a student who is retaking the exam.

After entering the classroom, Kuro keeps his head down, circles the room, and then sits beside Nguchi.

He is certain that members of the organization have already prepared for his arrival. They have created an answer key using colorful rice grains scattered across the floor. As Kuro starts writing his answers, Naguchi suddenly screams. He believes the rice grains are some kind of insects. [music] The teacher tells him that if he is bothered, he should clean them up. Kuro realizes that something must be done. She drops her eraser, bends down to pick it up, and cleverly loads a paper ball into a straw. She then shoots it toward [music] Naguchi.

Naguchi screams that someone has just touched her. She even begins accusing the teacher of being a perverted old man. The teacher responds calmly, saying that he does not have arms that long.

While the argument continues, [music] Kuro rapidly fills in one answer sheet after another. Before he can complete the math exam, the teacher rushes toward Nguchi and kicks [music] the rice grains across the floor. With no other option left, Kuro starts acting dramatically and urinates on the spot.

[music] He begins crying and claims that he was so nervous about the exam that he drank too much water. The teacher calms her down and explains that the exam is only a formality. >> [music] >> He assures her that even a blank paper would be enough to pass. Wanting to learn more about the school, Kuro [music] waits for Naguchi on the way back. They begin walking home together.

Since Kuro's house comes first, he invites Naguchi to visit for dinner sometime. Naguchi hesitates, but eventually [music] agrees.

They reach the rooftop of his house and continue talking. Naguchi mentions that some troublesome students in their class often tease him. He talks about a friend named Ada. The teasing became so severe that Ada eventually stopped coming to school. [music] Naguchi also reveals that there are secret tunnels beneath the school. These tunnels date back to World War 2. They once connected to a special military base used during the era of ninjas. Kuro realizes that the underground ninja group may be targeting this hidden base.

As the sun begins to set, Naguchi says that she should head home. Suddenly, she [music] slips from the rooftop and starts to fall. Before she can hit the ground, Kuro leaps forward and catches her. As they fall, the safety system in Kuro's [music] suit activates and turns into a cushion. Naguchi screams, faints with her mouth wide open, and loses [music] consciousness.

Kuro then takes her safely back home. That same night, a reckless boy tries to fly a drone near the bathroom of their neighbor, Kawado.

He does not realize that Kuro is sitting there wearing his invisible suit. Kuro uses his special electric baton to shock [music] the boy. It turns out that the boy is a friend of Nguchi. Kuro forces him to apologize to Kawu. The next day, he [music] takesa to school. Kuro assures him that he will protect him.

However, he also warns that a will have to pay a fine of 500 rupees every day. As soon as they reach the school, the boys start harassing a time. However, they have chosen the wrong moment because Kuro is also there.

Kuro hooksa's leg with his foot and slams into the other boy. The boy jumps in pain and stumbles back. Aa has no idea what just [music] happened.

Kuro calmly walks away and takes a seat in the back row. He realizes that he has forgotten his book. Sato, the girl sitting beside him, offers him hers.

Naguchi watches the scene with clear envy. Suddenly, a red laser light appears on Kuro's face. This laser is actually a secret signal [music] used by ninjas to communicate. Kuro immediately stands up and leaves the classroom.

On the rooftop, he meets a boy named Shyon. Cheyion is a high-ranking ninja. He was also present on the day Kuro dealt with the Russian man. Before Shyan could step into that fight, Kuro had already intervened. Likeda, Shyon is an undercover [music] ninja at the school.

His mission is to identify members of the underground ninja group. There is also another ninja living in disguise at the school. [music] He is currently serving as the discipline director. The director tells Kuro to meet him in the boiler room after class and then disappears.

Soon after, Kuro notices that a is being bullied again. Kuro activates his ability and vanishes from sight. He reappears wearing a box over his head.

One of the boys kicks him to see who he is, but instead falls to the ground. Kuro first sets a trap and then moves behind. He grabs arm and uses it to deliver a powerful punch to the other boy.

This ensures that the credit goes [music] to a not to Kuro. Later, Kuro goes to the boiler room to meet the discipline director. Without warning, the director pulls out a sword and attacks him.

Both of them mistakenly believe the other is part of the underground ninja group. Kuro counters every strike with precise and powerful moves. When he realizes that the director is not affiliated with the group, [music] he warns him to stop. He claims that a satellite is locked under the director and that he could end the fight instantly.

The director laughs and thinks Kuro is [music] bluffing. He believes a lowranking ninja could never control a satellite.

At that moment, a laser fires from the sky and slices the director's sword in half. The director immediately understands the situation and backs off. Kuro then leaves the room. As he steps outside, he notices Mitsuki, the most popular girl in his class, waiting for him.

She [music] gives him a strange smile and walks away without saying a word. At a nearby store, the sensor door opens and closes even though no one is visible. It appears as if something invisible has entered the shop. Moments later, items begin falling from the shelves. The woman inside tries to fight back.

She is also a ninja. However, the invisible man kills her. Suzuki receives a message informing her that her mentor, a fellow ninja, has been [music] murdered. Soon after, Suzuki herself is attacked. She realizes that the attacker must be from the underground [music] ninja group.

Only they possess a suit that allows complete invisibility. her own suit can only make her partially vanish. Later, as Sado is walking home from school, the same man grabs her. Suzuki warns him not to harm civilians.

The man coldly replies that Suzuki's death is not written there. He says it is written at Kodan High School. Meanwhile, Nguchi sits alone in her room, lost in thoughts about Kuro. For [music] the past few days, she has been unable to get him out of her mind. She keeps dreaming of a happy life with him. One [music] night, she suddenly sees Kuro sitting beside her bed, silently staring at her. Kuro tells her that a ninja working at a store [music] has been killed.

He warns her that an underground ninja group may be planning an attack. A violent clash is about to break out at their school. Kuro tells Naguchi not to come to school for the next few [music] days. Without saying anything more, he jumps out of the window and disappears.

The scene then shifts to a man running as if he is being hunted. Suddenly, a ninja star chases him through the air. At the first opening, it pierces his leg and he collapses [music] to the ground.

The man's name is Seruda. He was once a ninja from Kuro's team known as Nin, but he has since left the group.

The invisible figure pursuing him offers him a choice. [music] He asks Seruda if he wants to join the underground ninjas. Sera immediately agrees, saying that he enjoys killing people. He demands to know who the next target is. It is then revealed that the invisible ninja responsible for killing other ninjas is Seruda [music] himself.

The next morning, as a student heads to school, Seruda decapitates him with a [music] single strike. He takes the body with him and disappears.

Despite Kuro's warning, Naguchi goes to school [music] to look for him. At the entrance, the school director notices her. Nagguchi desperately explains everything Kuro told her about the school being destroyed.

The director realizes that a battle is about to erupt. He hands Naguchi [music] a ring and asks her to give it to Kuro. He urges her to find him, saying that the matter is extremely important. [music] Shortly after, Seruda arrives inside a classroom with the students body. Still unseen, the headless corpse suddenly drops in front of everyone.

The classroom erupts into [music] chaos. Sera begins killing students one by one. Some manage to escape, but Seruda continues chasing them. Soon, Suzuki and Shy receive news that an underground ninja is attacking the school.

Suzuki arrives and witnesses the massacre with her own eyes. She draws her wand and prepares to fight. The assassin removes his invisibility [music] suit and takes off his mask. Suzuki recognizes him.

Sera coldly asks if she remembers him. He reminds her that when they studied at this school, he loved her deeply.

He accuses her of mocking his feelings and running away. Consumed by anger and hatred, Seruda shows no mercy. The two clash in a brutal fight, Suzuki gains the upper hand and moves close to [music] victory. However, she fails to realize that Seruda's suit can absorb lightning attacks.

Because of this, her wand has no effect on [music] him. Just as Suzuki is about to be defeated. A man crashes through the glass. It is the same high-ranking ninja. Sera immediately understands the [music] situation.

Facing him, Seruda knows he stands almost no chance. That is why he puts on his mask and quietly disappears. However, Kaido has no trouble dealing [music] with this. He slashes his own arm at lightning speed and throws his blood towards Seruta. The blood stains Seruda's suit and reveals his invisible [music] body.

Kaiito immediately attacks Seruda with his sword. Seruda's advanced suit suddenly inflates like a balloon and blocks the strike. Taking advantage of the moment, Seruda manages [music] to escape.

Meanwhile, Naguchi continues searching for Kuro. She suddenly runs into a panicked. [music] Ida tells her that he, Kuro, and another boy went into the tunnel area. There is a rumor that a hidden passage leads [music] to an underground bunker. Ida explains that he and the other boy were too afraid to go inside. Now he is worried that Kuro [music] may be in danger. At the same time, Kuro encounters a girl inside the tunnels. She is Mitsuki, [music] the one who planned everything from the beginning.

Mitsuki is far more powerful than Kuro ever imagined. Kuro throws a bomb at her in an attempt to stop her. Moments later, she is seen hanging from the wall by a single finger. [music] Kuro then throws two high voltage cables at her. She catches them with her bare hands as if electricity has no effect on her. Elsewhere in the school, Seruda continues wandering through the corridors. Suddenly, [music] Shyon appears in front of him. Shyion draws his sword and begins confronting Seruda with incredible [music] speed and skill.

He cleverly scatters broken glass across the floor. This allows him to track Seruda's movements by sound. Even his teddy bear helps [music] pinpoint Seruda's exact location. Shyon manages to pin Seruda against a wall. Sera would have been killed by a satellite strike within seconds.

However, [music] he escapes at the very last moment. Shyon chases Seruda and catches up with him on the rooftop. He delivers a powerful sword [music] strike, but only Seruda's empty suit remains behind.

Seruda suddenly attacks Shyon from behind. Shy tries to evade the surprise assault, but his sword snaps in half. Although Shyon is the more skilled fighter, the underground ninjas possess superior weapons. During the struggle, Shyon suffers a critical wound to his shoulder.

Wounded and terrified, he can only defend himself with half of his [music] broken sword. He is on the verge of defeat. At that moment, Kaido arrives and turns the situation around. He drives [music] his sword straight through Seruda's body.

Sera's rampage finally comes to an end. Kaido saves Cheyen's life. Deep inside the tunnels, Kuro is [music] losing his fight. He realizes that defeating Mitsuki is nearly impossible due to her overwhelming power. Still, Kuro wants to understand her true [music] motive.

He asks why she is doing all of this. Mitsuki finally reveals the truth. She deliberately spread false information to lure all the ninjas to the school. This allowed them to activate the laser satellite and locate its position. By hacking the data, they managed to pinpoint the satellite.

Now, one of their allies has already reached it. [music] One of their special suits is even capable of functioning in space. As Mitsuki launches another deadly attack, Kuro struggles to defend himself. He barely withstands her immense strength. In reality, he is only buying time. He is waiting for his friends to arrive and save him. [music] Just then, Naguchi arrives with a Naguchi gives Kuro the ring that the discipline director told her to deliver.

Kuro [music] activates the ring and extends its antenna. At that moment, a drone arrives carrying a sword. Kuro grabs the sword, kicks Mitsuki [music] into a cloud of dust, and looks for an opening. Soon, the two face each other in a fierce confrontation. [music] Kuro quickly realizes that attacking Mitsuki head-on is a mistake. He understands that he must dodge and strike [music] suddenly. His vanishing suit proves useless because it only hides his upper body. Even after activating it, Mitsuki can still see him clearly.

Kuro [music] keeps questioning how long he can survive fighting like this. Each attempt ends with him being overpowered. In [music] the end, he accepts that he cannot win through normal means.

Kuro realizes there is only one way to defeat Mitsuki. He launches a direct assault using a powerful technique. Putting his own life at risk, he charges forward without hesitation. [music] Kuro's sword pierces straight through Mitsuki. At the same time, Mitsuki's blade strikes Kuro. Kuro forces Mitsuki back and she pulls the sword out.

Mitsuki collapses to the ground. Kuro [music] has reached his physical limit. Badly injured, he stumbles and falls.

Naguchi rushes to him, lifts him up, and helps him escape. Meanwhile, a member of the underground ninja group infiltrates the satellite. He uploads a virus into the system and takes control of the laser network.

With a single turn of the dial, the power is raised to maximum. [music] The laser locks onto the school as its target. After expanding its output, the laser completely destroys [music] the school.

The massive explosion sends violent tremors through the underground bunker. The bunker begins to collapse and the exit is far away. Naguchi and Kuro try to escape, but Kuro is critically injured.

Fearing that he will not survive, Kuro removes his vanishing suit. He places it over Naguchi to protect her. Debris begins crashing down all around them.

After some time, Naguchi emerges alone. She realizes that the special suit [music] saved her life. Kuro sacrificed himself to save her and protect the world.

However, at the end of the film, a final twist is revealed. [music] Kuro's twin brother, Jurro, appears for unknown reasons. He comes to meet Nguchi, leaving the story [music] on a mysterious note. If you enjoyed the video, please like it and subscribe to the channel.
