Hiruma Eriko was a samurai-ko of the Crab Clan. A talented student of the blade, she was sent to the Hundred Stances Dojo. Eriko challenged the sensei as soon as she felt ready, as it was tradition, but was defeated. She spent more years to perfect her knowledge of the Hundred Stances style, becoming one of the oldest student of the dojo. Eriko taught junior Crab students, attempting to train the perfect student, one who could win the position of sensei. Her advancing age and lack of outstanding results have led her lords to suggest she should retire to the Hiruma lands to teach a new generation of warriors.
