Osu is a supporter of SPOON and the leader of FAKE KNIFE.


Osu is a blue-haired young man who stands at 167 cm (5'5"). He is pale, presumably from his ill disposition. He often wears a long-sleeved turtleneck, pants, and a sort of mid-arm length, two-toned, v-neck robe, which he ties at the waist with a fabric belt.

Background Edit

He comes from a wealthy family, but did not contact them due to a poor relationship with his father. Number 1 was also not on good terms with Osu's father, to the point of throwing a chair at him, even though he and Number 2 cared for Osu when he was a child. During some point, Osu moved away and lived with Number 1 and Number 2.


When SPOON was in danger of shutting down because KNIFE had 'disappeared', it was Osu who intervened and made FAKE KNIFE, so SPOON can maintain its purpose.


He is incredibly kind and polite, even portrayed as an angel in the cartoon. For example, when Naga was depressed that he didn't feel that sad when he heard Venom and Tracey had died, Osu told him that, "You're trying to feel sad, and to remember them both. Only a good person would do that." Even with his kindness however, he doesn't hesitate to speak out his mind.

It also seems he has a positive(?) worldview, as he just smiles and say Dana is full of energy as usual when Dana is beating up Number 1. It is unclear whether this only applies to Dana or not.

Because of his personality, he gets along with almost everybody, except for his parents.

Contrast to his angelic personality and looks, he likes looking at porn magazines. In fact, his hobby is collecting these erotica. He has a shelf packed with them to the brim.
