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...
It's all a dream... A dream,
 a dream, a dream, a dream...
...هذا حلم... حلم، حلم، حلم، حلم
Ich träume.
Un sueño… Un sueño…
Un sueño… Un sueño…
Oui… dis-toi que c’est un rêve…
Sto sognando... Sto sognando,
sto sognando, sto sognando, sto sognando...
Sonho... Sonho, sonho, sonho, sonho...
Я сплю... Сплю, сплю, сплю, сплю...
