Looking for Mangas

Looking for mangas I read long time ago, probably I read them in other site. They had similar storylines but now I can't remember the name. There were some details I may have changed due to lack of memory.

Manga, black and white. Short story, maybe one shot.
Kind of old, maybe 5 years+
it had a shounen-aish feeling but I think it wasn't tagged as that.
They were two male friends who were very close (one blonde and one black hair). They were angels or some type of otherworld spirits that were roaming in the world. There is a corruption happening and they are warned to be careful or they are going to be executed if they are corrupted. The black hair angel couldn't find his friend. But at the end, he finds his blonde friend who got infected by the corruption. I don't remember if the blonde friend is executed or commits suicide.


Other manga, shonen -ai. I think, Old manga 10+ years maybe?
The ML is the reincarnation of the most powerful exorcist from the past, whose power was sealed for thousand of years and now the seal broke. As a child, everyone in the village is happy that he was born.
They tell him not to go into the forest. He discovers there is a cabin with many seals, and a blonde child confined, I think he doesn't have an eye or it is covered. They became friends, until the confined child gets out and somehow the village starts burning. They grow up, and the ML, now in high school is looking for the blonde child who burnt the village.
Looks like the blonde child was in fact the reincarnation of the person who sealed the powers of the ML's ancestor. I started reading that one in another site, but I never knew the ending.

Thank you. I have been looking with every tag possible in mangaupdtes and I think I got cuckoo cuckoo
