Real name: Hiroyuki Tsunekawa
Alias: Emperor of the Ruins
Height: 170cm
Birthday: January 18
The Emperor of the "Light Club"
Originally a transfer student who joined the club midway, but before long replaced Tamiya to become the center of the club.
After meeting a fortune teller in his childhood, he harbored ambitions of world conquest, created the robot Lychee, and captured the beautiful girl Canon. Since joining, he has had a twisted love relationship with Jaibo, who approached him.
I don't think Zera actually likes Jaibo in that way.

Commonly known as: Niko
Real name: Narutoshi Ishikawa
Alias: Knight of Loyalty
Title: Einz (No. 1)
Height: 170cm
Birthday: September 7
Has a shaved head and a scar over his right eye. He harbors a near-insane loyalty to Zera, a devotion so deep he would even crush his own right eye and offer it to him (however, unlike Jaibo, his feelings seem to remain within the bounds of respect and loyalty).

Commonly known as: Raizo
Real name: Raizo Ichihashi
Alias: Maiden of Darkness
Title: Zwei (No. 2)
Height: 165cm
Birthday: June 2
Although he is a bona fide boy, his gestures and mannerisms are effeminate, and he speaks using feminine speech. He also appears to have a gender identity disorder. He is skilled at sewing, and Lychee's face and clothes are his handiwork.

Real name: Riku Kaneda
Alias: Eyes of Gloom
Title: Drei (No. 3)
Height: 160cm
Birthday: May 17
An early member of the Light Club, along with Tamiya and Dafu.
Has a habit of biting his thumbnail. He hides one eye behind his long, grown-out bangs, and the shadow cast over his face makes him look sullen (though it's said that which eye he hides isn't fixed).
He is childhood friends with Tamiya and Dafu.

Commonly known as: Dentaku
Real name: Takuzo Suda
Alias: Science Boy
Title: Vier (No. 4)
Height: 155cm
Birthday: February 4
Has a shaved head, freckles on his face, and wears round glasses. Despite being a middle school student, he handled Lychee's programming (Zera recognized his abilities and brought him into the Light Club), and for that reason, he took great pride in his skills and technical prowess.

Real name: Katsuya Tabuse
Alias: Dreaming Eyepatch
Title: Fünf (No. 5)
Height: 160cm

He doesn't leave a particularly striking impression, but he's been seen making chuunibyou-style remarks.

Real name: Hiroshi Tamiya
Alias: Bullet of Truth
Title: Sechs (No. 6)
Height: 185cm
Birthday: March 24
The initial leader of the Light Club and the boy who founded it.
He questions Zera's methods and the state of the club after Zera's arrival, eventually coming into conflict with him.
He was originally skilled at pachinko and chess. He has a younger sister named "Tamako" who attends kindergarten. He has a tough, no-nonsense personality and seems to be popular with girls.
He is childhood friends with Kaneda and Dafu.

Title: Acht (No. 8)
Height: 165cm
Birthday: October 30
A rare, slender beautiful boy with a girl-like countenance.
Pale-skinned, with black eyes and black hair. His hairstyle is a bob with outward-turned ends, and long bangs hang over his face. Following Zera's orders, he always keeps the collar of his school uniform fully buttoned up to the top.
His catchphrase is "kyaha." He sometimes hums strange songs.
Though he is male, he harbors feelings for Zera that go beyond friendship, feelings that date back to when he was in elementary school.
