クワトロ 亜空

He is a prince of deposed by UHOS Rojio Dynasty, Haspar. The dynasty ruled Russian Kingdom before it's fall. He couldn't fulfill the duty of an imperial family member and now reproaches himself for this, so using a pseudonym "Colonel Quattro Akua" and wearing a mask. Hates how red color is using by sharists.

Can move a three times faster then normal people, like meteor. He has achieved this by continuous and incessant trainings in the deep part of hidden welded shut prison of the one of Lager's camps and a special mushroom "diet".

Likes: all red things.
Hates: white wood horses.

"Prince?.. No, am not. Before the day of Soviet's fall I am now Colonel Quattro Akua. No more, no less."

"Run away!.. This place is not for criminals to detain, but for this monster to seal off!.." — Some Japanese admiral about Quattro Akua.
