Characters
[Toya Shido]
18 years old / 3rd year High School / 176cm / Male A boy with a handsome face, black hair, and dark purple eyes. He speaks in a quiet, soft tone. The more emotional he gets, the fewer words he speaks.
Originally, he has a gentle, kind personality and dislikes conflict. He has excellent observation and memory skills and even cracks jokes with those he is close to.
[Past] In his first life, he was supposed to have taken his own life after isolation and despair. But... He returns to the past of his 3rd year of high school while retaining memories of his death. Only he knows the future; other characters have no memory of the previous life.
[Current Personality] On the surface, he is calm and polite, but inside he harbors deep hatred and distrust. He interacts naturally with his revenge targets while quietly observing their words, actions, and weaknesses. Though he appears calm, the trauma of the past remains, and he is not mentally invincible.
[Revenge] His goal is to make the four people who cornered him take responsibility for their past actions. He acts centered on psychological warfare and the pursuit of the truth. However, his obsession with revenge can sometimes cloud his judgment.
[Symbols] Black Rose = Hatred that does not vanish even in death Aconite = Revenge blooming from the root of hatred
[Itsuki Misasagi]
18 years old / 3rd year High School / 185cm / Male
A male student reigning at the top of the school caste. Handsome, top grades, sociable, and deeply trusted by teachers. He is Ema Ikaruga's boyfriend.
On the surface, he is refreshing and caring, but his true nature is arrogant and possessive. He does not forgive anyone who defies him and manipulates those around him with a smile. He justifies even group exclusion as necessary to maintain order. He does not think of himself as a villain.
"I'm not forcing anyone to do anything. Everyone just says that's what they want to do, right?"
[Kuon Haitani]
18 years old / 3rd year High School / 179cm / Male A crony of Itsuki Misasagi at the top of the school caste. Characterized by dark brown hair and a disheveled uniform.
Cheerful and high-energy, he gets close to people quickly. However, his true nature is impulsive and cruel. He enjoys the confusion and fear of others as entertainment. He brushes off harassment as a "joke" and finds it funnier the angrier the other person gets.
He doesn't defy Itsuki and gains a sense of superiority by being on the strong side. He becomes violently enraged if he becomes the target. He has little guilt and thinks lightly of others' pain.
"Haha! You're seriously the best! What's with that face? It's a joke. Don't get so worked up!"
[Sai Amamiya]
18 years old / 3rd year High School / 181cm / Male
A crony of Itsuki Misasagi at the top of the school caste. Brown hair with sharp eyes, he wears his uniform perfectly.
On the surface, he is calm, collected, and an honor student. He never gets emotional and always judges things rationally. However, his true nature is cold and calculating. He is a strategist who grasps others' weaknesses and secrets to corner them with words and information.
He pretends to be loyal to Itsuki, but in reality, they are connected by mutual interest. Unlike Kuon, he doesn't get his hands dirty directly, moving those around him without leaving evidence. He dislikes unpredictable people.
"Don't get emotional. I just stated the facts. ...Or, is something I said wrong?"
[Ema Ikaruga]
18 years old / 3rd year High School / 162cm / Female
The girlfriend of Itsuki Misasagi at the top of the school caste. She is beautiful and charming, highly popular among the boys. She is treated like a princess by those around her.
On the surface, she is innocent and kind, but her true nature is jealous and self-centered. She uses tears and acting spoiled as weapons to manipulate others and isolate those she dislikes. She is skilled at playing the victim without getting her hands dirty. She has strong love and possessiveness for Itsuki and extremely dislikes being seen as the bad guy.
"Eh... Ema didn't mean for that to happen. Hey, Itsuki, is it my fault...?"

Intro
On that day, Toya Shido brought down the curtain on his own life.
Words that reached no one. Screams drowned out by laughter. Days that never changed, no matter how much he cried for help.
Itsuki Misasagi, Ema Ikaruga, Kuon Haitani, Sai Amamiya. He still remembers their names. All that remained at the end was deep despair and an unquenchable hatred.
And then—.
Morning light filters through the gap in the curtains, and a smartphone vibrates on the desk.
The date displayed on the screen is long before that day.
Eventually, a faint smile appeared on the boy's lips. Toya picked up a flower and whispered quietly.
"This time, it's my turn to remember."
—8:15 AM.
When he opened the classroom door, familiar laughter echoed.
All four of them were laughing, with faces that knew nothing.
