ミュカ

While he never appears alive in the game, Muca is a bishōnen who attracted the attention of Guys and other boys long before the game started. 

-Warning! Major plot !-

It will be revealed that Guildias kidnapped Muca and dressed him like a girl. Guys saw Guildias with Muca, and Guildias (incorrectly) assumed that Guys recognized him. Afterwards, Muca's family hired the private detective Jared to find him. However, Guildias murdered Jared and framed Guys for the murder, thus covering his tracks and setting Enzai's plot in motion. /
