I mean, i love Carnival phantasm as much as the next guy , but All around Type Moon would be even better, for a lot of reasons.
. It has Ryougi
. It has Saber and Red Saber crossover episode
. Prillya crossover episode
. Illya and Miyako Grow up episode
. Kenny Lancer maybe is hilarious, but waiter lancer is funnier imo XD
i Dont think is likely in the near future with all the fate projects ongoing, but i hope to see it animated someday.
