Onigiri
One of Ikki's childhood friends, Onigiri (オニギリ, Onigiri?) is also part of Kogarasumaru. His head is in the shape of an onigiri. Onigiri is a pervert and characterized as a pig. He has an unusual way of using his perspiration, usually during overall perverted moments, to create illusions. He also has a strange way of using his AT by sitting upside down on it (to the chagrin of his female schoolmates whose skirts he tends to look up while doing this). This way of riding proved to be very dangerous, for both Onigiri and his opponent, as he flails his legs back and forth(doing damage if he's close enough), but can also fall off, landing directly on the point of his head and streaking on the ground until he stops (this, however, is never shown, only an image of an actual onigiri in said position). He is in the same class as Ikki, and follows the "Smell Road." (the authenticity of this road is arguable, since one can't really tell if this was just another one of Oh!Great's jokes. However stated by Akito/Agito in Kyoto, there are "hundreds" of roads. But out of those only 8 roads can be called Road of King.) He can also go as fast (or possibly faster) for short spurts than Ringo, when the right motivation is present. At chapter 171 Onigiri is seen trainning with his friends in order to get stronger than before, most of his techniques have the ability to affect the enemy's senses, create illusions. On many chapters he's seen as an upside down buddha with supernatural powers.
