The now dead Ronin who disgraced the Tetsugai, father of Kuen Sun
A tall man in his mid thirties, Okoshima was a strong samurai with jet black hair and eyes.
Okoshima fled the battlefield during an enemy assault, resulting in the death of a superior officer in the Tetsugai clan. When his clan discovered this, they expected him to commit Seppuku, but Okoshima refused, and became Ronin. Taking on mercenary work to feed his family, he made the mistake of accepting a lucrative contract to assassinate the son of a Tetsugai warrior. In retaliation, the Tetsugai killed Okoshima, his wife Sayumi, and his son Kuen, or so they thought. Kuen sun survived and was nursed back to health by martial arts master.
