After saving his opponents from their assaulters, Raishin cancels the duel but is forced to search for a new way to gain access to the Party. Driven by the tragedies of his past, Raishin fights alongside Yaya to rise to the top and claim the title of Wiseman. [Written by MAL Rewrite]

Ikaruga Natsuki, a boy who lost his mother and his leg in an accident some years earlier, returns disillusioned from a harsh life in the big city to find his old countryside home half-swallowed by the sea.

They take Mahito out of Tokyo to seek refuge in his late mother's rural family home. There, Mahito is constantly taunted by a strange gray heron, who seems to have taken an interest in him.

He soon finds himself falling into another world below his, where life and death seem to be entwined. As he navigates through this foreign realm to find Natsuko, Mahito must understand what it means to live if he wants to safely return home.
