Okubashi Mutsumi

A man dies alone after living a stagnant and fruitless life — but that's not where his story ends, as a boy named William is born into a land of fantasy and magic.Raised in a city of the dead by his new family — a mummy, a skeleton, and a ghost — he can remember glimpses of his past life, enough to know his time on Earth was wasted, and he vows not to let that happen again. Schooled in magic and combat, Will sets out on a journey to see the world. Along the way, he'll meet beings of all shapes and sizes. Each of these people has a story to tell and a lesson to teach Will about how to live his life to the fullest.Character Designer: Rin Kususaga

On his way back from a business trip, negotiator Shindou Koujirou witnesses a large cube appear out of thin air, which swallows the plane he was riding, along with all of its passengers. Inside the mysterious cube is a being in the form of a human man, named Yahakui Zashunina. He is from a place called the “anisotropic”, and he wants to “advance the world”.

Living isn't easy. When Haruhito awakens, he's in the dark. He doesn't know where he is, why is he here, and where he came from. Around him there are several men and women who have the same circumstances. Together, they advance forward away from the darkness, and a world they've never seen before called "Grimgar" spreads out before them. Memories, money, special powers — this is the reality we who have none of those things have obtained.
