Project: ABYSS

In the beginning, two powerful beings fought for power over the world: the God of Heavens and the God of the Abyss.

Kano Tadomeki is a 27 year old man who's living his life happily without any stress or problems. He is married to Akari and the couple shares a loving and balanced relationship. Tadomeki's professional life revolves around his job in an IT company, where he opts for a low-profile approach, avoiding the pursuit of promotions.
One day they are both preparing for a meetup with their old friends happening on a festival. The story takes a tragic turn when, on the way to the meeting, Tadomeki and Akari are involved in a severe accident. While he loses his left arm, his wife is taken away by a mysterious man. How much is he willing to sacrifice just to save the ones he loves?
