Seiji's got a lighthearted and playful personality, always having a witty crack on standby. he's outgoing for anyone, even the strangest of strangers. He was raised as a fighter, spending most of his childhood being trained by his grandfather, Akuma.

This tug of war between his two elders is a huge aspect of Seiji's path in the story.
