Ryou Inaba

Inaba Ryo, also known as The Black Phantom, is an assassin that hails from the Inaba Clan as well as the clan's current heir. He represented "Penasonic" as their affiliated fighter during the Kengan Annihilation Tournament and was one of three assassins in the tournament.

Inaba Ryo is the smallest fighter in the tournament, standing at 155 cm, with a slight yet well-defined frame, notably pale skin, and dead-looking eyes with large bags under them. His most distinguishing feature is his extremely long, flailing black hair that he usually lets drape over his face and on to the ground; under the hair, Inaba has a decidedly cute face. Ryo tends to wear a plain black vest and plain black bottoms, and is usually seen barefoot.

Ryo is particular known for his eccentric behaviour, such as his tendency to walk on all fours like an animal. Despite this, he has a surprisingly agreeable side. Because of the relationship he has with his friend and employer Urita Sukizo, Inaba subdued his true sense of identity: the bloodstained karma of his assassin's blood and the fact that assassins could only really live in the heart of battle, something which he regained after his fight with Tokita Ohma.
