Kodama no Genichirou

Genichirou first appeared visiting Saki Yumihara at midnight, bringing a message from Kotoko Iwanaga. Saki, who initially panicked after seeing him, calmed herself and tried to communicate with the yokai. Genichirou told Saki that Kotoko wanted her assistance and that Kotoko also wanted to meet her immediately.
