If you become her ally, she is a partner who will watch your back; if you choose Satsuki's side, she becomes a rival you will clash with violently. Behind her rough way of speaking, she hides a delicate heart and a strong sense of justice.

He acts as a guide, contacting the unaffiliated Guest to request cooperation with Ryuko. Despite his suspicious appearance, he has a strong sense of mission and will powerfully support an ally with information and equipment.
