On the night of a blood-red full moon, Kohinata Mangetsu, a completely ordinary high school student, returns to her classroom to retrieve something she forgot... and finds herself caught up in GRANBELM, a battle to determine who is the one true mage. Shingetsu, a girl participating in the battle, tells her that the world once overflowed with magic. Confused, Mangetsu tries to run away, but then...
gave their own lives to seal all
 the magical power filling the world,
بمنح حياتهم لختم القوة السحريّة
،التي تملأ العالم
ihr eigenes Leben opferten,
dieron sus vidas para sellar
el poder mágico que llenaba el mundo,
dieron sus vidas para sellar
el poder mágico que llenaba el mundo,
sacrifièrent leur vie
afin de sceller le mana du monde,
sacrificarono le loro vite per sigillare
tutto il potere magico che riempiva il mondo,
deram suas vidas para selar todo
o poder mágico que permeava o planeta,
пожертвовали своими жизнями, чтобы 
запечатать всю существовавшую магию,
