After the Master of the Arakawa River Was Taken Away

Seimei tops x Master of the Arakawa River bottoms.

Many years ago.

The first time they met, one of them was still a child, and the other saved him.

The second time they met, he heard Kuro Seimei's wish and went to stop him. His old acquaintance had become a renowned and powerful onmyoji in the capital.

The third time they met, he was saved by him once again, and it all happened so unexpectedly.

Their paths had never been meant to cross, yet somehow they did.

Much later, after Seimei finished drawing his true yokai form, he pondered for a moment and suddenly said, "I always feel like I've known you for a very long time, Arakawa."

"Do you? I don't remember."

Someone lied with a perfectly straight face, unwilling to admit the truth.

Even today, the Master of the Arakawa River has once again skipped out on his territory's business to come steal some leisure time.
