3 Works in Onmyou Taisenki
Kogenta posted an advertisement for a Roommate. A potential candidate arrives while the Byakko is sound asleep . . .
Time passes as Riku continues on with his life, never once noticing Kogenta watching over him from afar. But when Riku's life takes a turn for the worse, not even the threat of ending up in Naraku will stop Kogenta from protecting his Toujinshi and making sure the ones responsible get what they deserve.
After the end of the series, Riku tries to understand his feelings for Kogenta and why he was able to let the Shikigami go.
