@22_Vanitas Yeah, thinking about it in Nasu collabs (excluding Mahoyo, which is basically more of a Carnival Phantasm) they never add MCs, not even as NPCs
Arc is a guest to advertise Tsukihime Remake. While Ciel... I still don't understand why she's there.
@22_Vanitas TBF, they did the first when they were still broadcasting the anime and for the rerun they did the classic limited 4-star, without changing the event much because they're too lazy. They could have done the collab with the movies but they preferred to do the Riyo collab instead.
@22_Vanitas I only remember him doing this with CCC collab (probably because he preferred to give more focus to writing Melt's character).
Still fuck him for not including Shirou
