I Regained My Memories and Became Rich After Getting Divorced - Chapter 604 - : Removal of Toxins

Side story of Kyoukai Senjou no Horizon bundled with the first press release of the 1st, 3rd, 5th and 7th Blu-ray volumes of both seasons of anime.

This side story follows Asama, Kimi and Mitotsudaira aboard Musashi one year before the beginning of the main story, as Asama is considering to create a music band together with her two friends for the next festival in Aki, a territory under the governance of K.P.A. Italia.

A youth crept on the ground in a snowy night. Hours ago, his tendons were cut because the girl he liked plotted against him. A mysterious middle-aged man saved him, and a pair of gigantic purple pupils appeared in the sky. Under the thunders and lights, the rare Demon Pupils and Sacred Body were awakened. That was what he should have been.

However, in this world, strength was the only way to support a man to live. His adoptive father died for covering him. His true love fell into the abyss for saving him. He wanted to rise up, to take revenge, and to protect the ones he cared about.

Occasionally did a strange figure confuse him. Behind the huge demon pupils, he often saw a thirty thousand feet tall black figure. What was it? Who was that?

It was said that the ultimate bloodline of the universe was the Primal Chaos Divine Body. It was a divine existence which could break the heavens and annihilate the world in a second. However, this sort of divine body had been extinct ten thousand years ago.

Could it be that apart from the Sacred Body, there was another body in him?
