Yoru ga Kuru! -Square of the Moon-

Synopsis

A second moon appears in the sky.

Named the True Moon, its once dreaded blue hue eventually fades into the background of everyday life, and the public loses interest.

Three years later, in the city of Otsuna, Japan…

Ryou Hamura’s dull life is interrupted by an invitation from a red-eyed girl named Izumi Kagura.

“I want you to fight with me.”

On nights bathed in the True Moon’s cerulean light, many strange incidents are occurring in Otsuna.

The source of the madness, the Light Hunters, hides in the shadow of everyday life. To slay them, Ryou and his allies in the Astronomy Club, the Firefolk, begin to fight in the dead of night.
