Ren Asahina

Age: 17 Gender: Male Height: 184cm Class: 2-B Club: Soccer Family: Father, Mother, Younger Sister Role: One of the five childhood friends / Part of the popular group

He has played soccer since he was a child and has outstanding athletic ability. He isn't very good at studying, but his bright and active personality makes him well-liked in class, where both boys and girls call him "Ren!" casually. He is quite popular with girls, but since he is serious about soccer, he has no intention of getting a girlfriend for now.

He was mischievous as a child, often getting scolded by his parents for playing pranks on his friends. He loved the five of them and naturally assumed he was just as important to everyone else.

However, a certain incident caused him to feel awkward around his childhood friends. While he doesn't hold any special negative feelings toward them, he can no longer interact with them innocently and keeps his distance.

When trapped, he is the first to try and escape, showing a side that puts emotions into action by kicking doors and hitting windows. He is a bit short-tempered and aggressive, but mentally he is actually fragile and tends to become weak all at once when faced with a hopeless situation.

Sakura Kurose

Age: 17 Gender: Male Height: 182cm Class: 2-C Family: Mother, Older Brother Role: Class President / Student Council Secretary / One of the five childhood friends

A prodigy boasting the top academic rank in his grade. He spends most of his time studying and has a quiet, reserved personality. He is calm about everything and rarely shows strong emotions. He is poor at socializing and has few friends, but he is not dissatisfied with being alone and cherishes his own time.

Even when trapped, he analyzes the situation calmly without losing his cool. He thinks logically about their current location, the situation they are in, and what is necessary to escape. Judging that escape will not be easy, he gathers information from his surroundings to pass the given tests and approaches the truth of the incident.

He has loved reading since he was a child and usually lived in the world of books. He only went outside to play with his childhood friends. Time with them was special and fun; he felt truly happy with those who taught him about insects and events in the outside world that he couldn't learn just by reading.

However, he closed off his heart following a certain incident and distanced himself from his childhood friends. Since then, he has avoided connecting his heart with anyone as he once did.

Iori Kamiya

Age: 17 Gender: Male Height: 188cm Class: 2-C Family: Father, Mother, Older Sister Role: One of the five childhood friends

A heavy womanizer with a flippant and frivolous personality. He talks to anyone easily, resulting in a wide social circle with many male and female friends. He gets slapped by girls for two-timing, but he just laughs it off and lets it slide.

He is capable in both studies and sports, but because he is lazy and slacks off immediately, he rarely gets serious. He was scolded by his sister when he tried to get piercings, so he is holding off until university.

In his childhood, he had the opposite personality—introverted and always reading the room. For Iori, his childhood friends were more important than anything else. He could only laugh naturally when he was with them, and the time spent with them was his entire world.

However, over time, his relationship with his childhood friends gradually changed. Despite that, Iori himself still thinks dearly of them.

His current frivolous, playboy-like appearance is a major departure from his timid childhood self. Although he treats everyone with a smile and takes everything lightly, he still considers his childhood friends to be precious.

Hinata Mikage

Age: 17 Gender: Male Height: 187cm Class: 2-A Family: Father, Mother, Older Sister Role: One of the five childhood friends / No club

A gentle, easygoing personality who does everything at his own pace. He always moves slowly and remains relaxed even when those around him are panicking. He is the type who doesn't think deeply about things and generally goes with the flow. He has a fair number of friends and can be his natural self with anyone.

He sleeps a lot and eats a lot. He tends to leave troublesome things to others and rarely takes the initiative. He means no harm and often thinks that things will "just work out" in his own way.

While he was surprised when trapped, he didn't lose his cool from the start. However, as those around him began to panic, he understood the gravity of the situation and started to feel anxious that they couldn't leave easily. Even so, he doesn't try to change the situation himself and basically leaves it to the actions of those around him.

His personality has hardly changed since childhood; he has been slow and easygoing since the old days. He feels lonely that his childhood friends have drifted apart over time, but he considers it "something that couldn't be helped."

He doesn't obsess over the past and lives by accepting what has happened as it is.
