As a boy named kouizashi who lived in Japan was on his way to school he was skipping out of happiness to see his gf.
He had felt as he was on his way to school tht smt was wrong because a month earlier a female(kohana) friend of his got stabbed with a kunai trying to stop kouizashi from getting from getting stabbed,as she was laying in his arms she confess are love for him.
He morned but he had never felt a feeling like he felt on this specific morning but thinking about his gf happiness took over.
As he arrived at school he rushed to second period as he found out his watch ran out of battery.
As the teacher made an example of kouizashi smiled softly as he saw his girlfriend smiling at him.
As kouizashi was instructed to sit down he heard a loud voice being closer to the door he was intrigued to look as he did show the schools emergency door lock down was activated he was looked out of all rooms his friend orichi arriving late as he came running down to corridor to hide.
He did as instructed but as he turned the corner his late friend kohana's father(karikei) was around the corner stopping them in their track.
Orochi started explaining to karikei what is happening but kouizashi notice karikei is not worried kerikei explained tht kohana died trying to save kouizashi in the process lost her life and the boys got 2 months of juvenile detention and now they are back at school.
He explained tht he had planned an attack on the school for two months and have a total of 20 men attacking the school.
While he is explained shots are fired and screams are heard he explains that everyone must know pain so he grabbed his knife stabbing kouizashi in his eye orochi trying stop him gets tripped and karikei stabs him in both of his eyes orochi being blind can't help kouizashi,kouizashi tries to attack but since karikei stabbed him in his left eye his right eye is blurb so karikei dodges one of kouizashi's attack and hits kouizashi on his left temple kouizashi being knocked is defenseless
Him thinking tht he stabbed kouizashi in the heart wanted to kill orochi kerikei taking out his gun wanted to shoot orochi as he pulled the trigger smt intercepted the bullet right before it hit orochi hit was kokoros school's past top student(Rinmaru) which graduated a year earlier kerikei who was born with only chi and can't use rinjutsu is ready to box with him.
By this time the Japanese shinobi police force is their with kunies guns and shuriken they sealed the school and worked it into the seal tht only positive energy can escape the dome so they attackers can not leave.
Rinmaru and karikei fight kerikei excell in hand to hand combat do to the lack of rin jutsu,rinmaru is noted tht the attackers have been captured so he takes out a chain throw it to kerikei and whipping it around his neck rinmaru jums in his chest push away with all his might and rips kerikei's head off
Every injured person is taken to the hospital and treated to their wounds.
A doctor talks to kouizashi and explains and explains tht the condition in his eye is not bad he explains tht they have been working on a artificial eye tht has God like vision God like powers and can use all rinjutsu and this eye is the last of the great Lords power if this eye doesn't work then they can't save China the doctor told him tht this project had a 99.9 percent death rate
Kouizashi having no living relatives and wanting to talk to his girlfriend about this finds out she is missing police informed him tht they think she got caught in the blast
