Sogetsu Kazama is one of the heroes from Samurai Shodown series.
History
When Sogetsu and Kazuki were infants, they were found underneath a bridge. It's unknown if they are truly related to one another but they became ninja of the Kazama clan. In Samurai Shodown V, Sogetsu is ordered by his clan to defeat a powerful water-demon named Suija. After much searching, he encounters the demon and engages him. With the help of his younger sister's powers, Suija is sealed away in his weapon.
When Kazuki leaves the clan to save Hazuki, the elders of the clan order him to execute his brother. Sogetsu eventually finds Kazuki at Amakusa's castle and allows Kazuki to rescue Hazuki while he stays behind to fight Zankuro. Soon after, he is slays Zankuro a second time and returns to his clan, telling his superiors that Kazuki has been taken care of; in truth, he allows Kazuki to fake his death so he and Hazuki can run away. Sogetsu was keeps a watchful eye on them in secret so they may continue to lead a carefree life. He continues to serve his clan, loyally following their orders and meeting his brother by coincidence from time to time, as well as eventually becoming the clan's leader in Samurai Shodown 64-2.
In Sen, his leadership is retconned and he is only a candidate for the position. However, fellow clan members has become torn at the thought of Sogetsu becoming leader, with one side respecting Sogetsu's abilities and the other being envious and distrustful of him. Genshinsai, the ailing leader, requests the youth to prove his worth to other members of the clan to dispel the conflict. Sogetsu agrees and is ordered to investigate the mysterious foreign ship.
Personality
Sogetsu is a stoic and reserved youth, locking away his emotions so he can serve the part of a ninja faithfully. He loves his siblings and shows his care by sparing their lives and remaining distant, despite saying to Hazuki that she is dead in his eyes. He quietly watches over them, careful to steer other members of the clan away from their locations. This is further emphasized in Kazuki's ending in Samurai Shodown VI where he helps his siblings reintegrate into their clan.
