Mouri Motonari

Motonari is the leader of the Mouri House. He was cursed by a youkai named Daidaara which halved his lifespan but as a side-effect transformed his body into super large size. While most human beings would not be able to withstand the curse and would just die, Motonari lived with it and in fact enjoys the side effect which made him a formidable fighter on the battlefield.
