캐릭터 프로필 이미지
Kureha

Motionless and cold. Not moving, not breathing, without her usual smile, Kureha just lies there. Only a cold shell of Kureha remains.

캐릭터 프로필 이미지
Yomi

The listless Yomi is looking down slightly, weeping. It must be because someone close to him died. His usual apathy is gone; he is crying.

Creator Comment

4 = Shi (Death) 9 = Ku (Suffering) It could also be read as "shiku-shiku" (sobbing). Try reading April 9th in hiragana. Yongatsu Kokonoka? Shigatsu Kunichi? Is that a bit of a stretch? 🥀 April 9th The day death arrives.
