The member of the idol dream rabbit sacrifice group is Nito Nazuna. He is radiant, really white and purple, and the captain is "Nito Nazuna"
Nito Nazuna is cheerful and sunny, originally belonging to the Valkyrie group, but later left the original team because of events made in Tenshouin Eichi. So I formed a rabbit team and took the post of captain. Then I trusted my teammate and gave him the captain.
