Samurai Shodown IV - Sogetsu Kazama [Slash/Upper Grade] (Neo Geo MVS) サムライスピリッツ天草降臨風間 蒼月

Sogetsu is a stoic and reserved youth, locking away his emotions so he can serve the part of a ninja faithfully.
He values his family and loves his siblings and shows his care by sparing their lives and remaining distant. He quietly watches over them, careful to steer other members of the clan away from their locations. Despite saying to Hazuki that she is dead in his eyes, he never implied abandonment at all. This is further emphasized in Kazuki's ending in Samurai Shodown VI where he helps his siblings reintegrate into their clan.
His ambitions for power are never clearly explained though it is implied that he maybe driven by ulterior and personal motives. Should opportunities to be the leader of their clan present itself, he will rise to occasion.
