I'm also confused as well v

so far, aoi was actually part of inugami family line, his father actually has brother that was a inugami's misstres (kind of god servant) and, yuuma brother whose chosen as another inugami's misstres, hakusei is falling in love with aoi.
truth to be told, aoi never knew about his father family, including about the inugami lineage that he has since he lived with his mom only.

hakumei i mean, i forgot his name

Thank you so much~
