S01E01 The Only Mages in the World
The night of the crimson full moon. The full moon of Konichi, who had been living a normal high school life, is caught up in the battle to become the only magician in the world...
After getting a glimpse of Nene's past, Mangetsu realizes what it means to fight in GRANBELM, but at the same time finds herself with even more questions about it. Still, now she knows that every participant has her own reasons for fighting. Meanwhile, Anna attempts to steal the Fugo family's powerful magic stone, which leads Suishou to give up on her and leave the Fugo household.
The anime takes place in a world that long ago featured the existence of magic, but has long since lost that ability. The story begins when the very normal high school student Mangetsu Kohinata meets Shingetsu Ernesta Fukami, who has migrated back to Japan from Germany, on a night with a full moon.
