Character Setting

Edit

Misumi Ikaruga is a free-spirited young man who lives for triangle shapes and is known for his boundless energy and eccentric behavior in the troupe.

Height: 175cm.

Motif flower: Dahlia.

Age: 19 → 20 → 21 → 22 (story progression).

Birthday: June 6.

Blood type: AB.

Misumi is perpetually upbeat and radiates pure, childlike enthusiasm.

His obsession with triangle shapes defines nearly every aspect of his life.

He’s extremely playful and unpredictable, often surprising his friends with bizarre comments or behavior.

Despite his oddness, he’s friendly and genuine, completely lacking malice.

Misumi works as a part-timer but mainly spends his days at the company’s dormitory, living in Room 203.

He is the grandson of the troupe’s original playwright, Hachizumi Ikaruga, and began living in the dorm without permission.

Growing up, he was considered strange and his family, except for his grandfather, mostly ignored him.

His younger brother, Madoka, belongs to GOD Theater, while their father is its playwright.

Misumi’s family relationship was strained after his grandfather’s death, but they reconciled following a significant incident.

His physical abilities are remarkable, making him adept at acrobatic stage scenes.

He can inexplicably communicate with animals, which both amazes and puzzles the group.

His acting skills are highly praised—even Tenma Sumeragi is shocked by his talent.

Nicknamed “Triangle Alien” by Yuki Rurikawa for his quirky nature.

Kazunari Miyoshi calls him “Sumii.”

He becomes close with Hyodo Kumon, sharing his dorm room with him starting from ACT2.

His younger brother, Madoka, is told by their father to stay away from Misumi due to his eccentricity.

He reconnects with his family after overcoming their past misunderstandings.

Misumi collects triangle-shaped items as a hobby.

He loves rice balls, considering them mystical because of their triangle shape.

He dislikes barrel-shaped rice balls.

As a child, he was seen as an oddball and mainly received attention from his grandfather.

He is one of the most unusual members in the troupe and takes pride in being different.

“Rice balls are mysterious! Triangle triangle!”

“San-kaku, san-kaku!” (Triangle, triangle!)

ACT1 (Age 19)

He settles into the company dorm, confusing many with his playful antics and endless fascination for triangles.

He quickly proves his talent by contributing high-energy performances to the troupe’s summer shows.
