Mystari's manga / #Curse(5)

After having his girlfriend stolen by a younger co-worker, Koumyouji decides to 'curse' Sakuragawa so that he turns gay.

Two families are tied together by a curse. Every 100 years, one person from each family must share the same fate for exactly one year. The pair will be subjected to 12 misfortunes where one will get hurt while the other must sustain their injuries in return. When Kagura Izumi was 7, his parents died in an accident. Since then, he has been living an ordinary life. Until the day of his 17th birthday where he meets a mysterious transfer student, Ichijyou Chihaya. However, this fateful encounter between them is only the start of their intertwined fate. For the next year, the two of them will be forced to face 12 misfortunes on the 13th of every month, a curse that has never left any previous pair alive.

In this land, humans and spirits used to live side by side. Taki was born with the mixed blood of both beings, inheriting the power as well as the curse. Now he has to find a way to control it, before it devours him whole.

In Yamane Akio's family, everyone seems to die early, and other relatives talk about a curse. Soon after his grandfather's death, Yamane comes down with an incurable disease, and in desperation he remembers his grandfather's last words -- that somebody was watching over them. After finding an odd fossil tooth that his grandfather kept, Yamane accidentally summons a guardian spirit, who promises to cure him. Maybe he should be pleased, but this guardian has some strange methods for healing.
