|“||I don't care about vegetables, chu! Besides, don't you dare complain about my Compa, chu.||”|
|Video game||Cyberdimension Neptunia: 4 Goddesses Online|
Born and raised in the back-alleys of Gamindustri, he knows just about every crook in town. Ever since Compa cared for him when he was injured, he's had feelings for her. They remain unrequited, however.
He has chosen the Adventurer as his class within this game.
In reality, he's a mouse, but since the Mouse race doesn't exist in 4 Goddesses Online, his avatar is a human like the other players. 
Warechu now looks like a human. He has the figure of a male youth. He has large eyes with red irises and black pupil and grey hair in a bowl cut. His attire is essentially a cosplay of his form as a rat. He has a hood that is in the shape of a rat's head. He wears a black shirt then a gray t-shirt over it and black pants. He has a black scarf with the broken heart design. He carries a beige bag and there is a tail that hangs out behind him. Behind him, is a pair of small red wings.
Warechu is foul-mouthed, dislikes being called a rat, and knows when fighting is futile. In order to play this game for free, he managed to get a hold of a ticket. He doesn't like working very hard though, so he hasn't even been raising his levels while playing. Instead, he earns money by selling recovery items at excessively high rates right outside various dungeons. He is also smitten with Compa, comparing her voice to that of an angel.
