Mochi-chan's Questions (2)

I'm trying to find this manga I read once; all I remember is it was a shounen-ai and the two main characters were like adoptive brothers. The one was adopted into the family to serve as the vessel for a demon/curse thing that is effecting his body, like I remember one chapter it really effected his legs and he couldn't really move much. The other guy was actually a member of that family and was really protective of the one with the demon/curse. They were dressed traditionally, in kimonos, if that helps.

I really want to re-read a manga I read awhile ago and forgot the name of. It was a shounen-ai manga about a boy whose family pretended to be exorcists in the past and now supernatural entities are appearing and causing trouble for him. A dragon/god(idk) is freed from a box or some form of scripture and decides to hang around, I'm pretty sure the boy named him "Hisui/Jade" or something like that.
