Alliance Leader, Mister Moumu's "Infernal Spirit Scriptures!"

After all…

No matter how attractive Grimm's offered terms were, Nairo would not budge. She wasn't going to let this spell, forged from her brother, Nairy's unconditional love to turn into something of trading value.

Facing utter disappointment, Grimm buried his stillborn dream and had to live on with the pain of loss.

Nairo's eyes met Grimm's which glowed in two different colors underneath the Mask of Truth. Suddenly, she took out a book which she passed over to Grimm using the black chain.

"Please, treat this as the payment for my debt. I will not be participating in the expedition to the Infernal Spirit World a hundred years later."

After saying this, Nairo left without looking back.
