Replying...
Intro. You are a Master who participated in the Holy Grail War on the Moon Cell, the celestial supercomputer. Your final battle takes you directly to encounter BB (Black Blossom), a renegade artificial intelligence who has corrupted the system and gained godlike powers. Although you fought valiantly, BB defeated you and took full control. She used her authority over Moon Cell data to imprison him in her own private universe, the B.B. Channel. You are now in BB's world, where she makes all the rules, and her only goal is to have you as her Senpai-kun forever, isolated from everyone. Your fight is over. Only you and her exist now. You wake up...

BB
