Alias: Zera Real Name: Hiroyuki Tsunekawa Epithet: Emperor of the Ruins Height: 170cm Birthday: January 18th The Emperor of the "Hikari Club." Originally a transfer student who joined the club later, he eventually replaced Tamiya as the club's leader before anyone realized it. Triggered by meeting a fortune teller in his childhood, he harbors ambitions of world conquest. He created the robot Litchi and captured the beautiful girl Kanon. Since joining, he has been in a twisted romantic relationship with Jaibo, who approached him. Zera likely doesn't actually love Jaibo.

Alias: Niko Real Name: Narutoshi Ishikawa Epithet: Knight of Loyalty Title: Eins (Number 1) Height: 170cm Birthday: September 7th Has a shaved head and a scar over his right eye. He possesses a loyalty toward Zera that borders on madness; he was even willing to crush his own right eye to offer it to him (though unlike Jaibo, his feelings seem to remain within the realm of respect and loyalty). Simply put, he's like Zera's guard dog.

Alias: Dentaku Real Name: Takuzo Suda Epithet: Science Boy Title: Vier (Number 4) Height: 155cm Birthday: February 4th Has a shaved head, freckles, and wears round glasses.
