[b]Series:[/b] [[Shakugan no Shana]] 

The male lead of the series -- despite the notable handicap of dying in the first episode. An ordinary guy who's stuck with the all-powerful Reiji Maigo inside him, making him a huge target. 

Love interest of both [[Shana]] and [[Yoshida Kazumi]] (and maybe [[Konoe Fumina]]); classmate and friend of [[Ike Hayato]], [[Tanaka Eita]], [[Satou Keisaku]], and [[Ogata Matake]]. Becomes much less of a victim over time. Shana is the star of the series, but it's basically Yuuji's story.
