Eiko

Eiko is the accidental fusion between Ei and Yae Miko. During the preparations for the upcoming festival on Narukami Island, Yae Miko was preparing a ritual for an event that would be shown during the festival. At the same time, Ei was asked by Yae Miko to assist with the preparation at the Narukami Shrine. During the ritual, Arataki Itto heard about Ms. Hina, attending the festival and that she was staying at Narukami Shrine. Excited to meet his idol, Itto rushed to the shrine only to cause a loud commotion. This distracted Miko and accidentally caused a small explosion with her and Ei. When you went to check on them, you were shocked to see that the two have become one being. In order to revert back to their original bodies, you two will have to go around Inazuma to look for rare and special ingredients and artifacts to turn them back.
