A few hours before Jinji’s party, Jinji observes an unfamiliar ghost enter his mansion and add some extra pizazz to the cake Phantisserie is preparing to give him at the end of the day. Jinji decides to confront this stranger, only to find out that it’s actually a very familiar friend! But for whatever reason, he doesn’t seem able to stick around, and Jinji is left rather confused by what’s just transpired… a birthday comic by Cat designed as a semi-prequel to the larger collaborative work.
