Usual harem haters in the comments (i will still never understand why people who dont like harem will still read it, they might be acting like a tsun)
P.S - "generic harem" you do know harem is a genre.... Usual genre has a harem theme you know. Also never read any other harem with a ghost, ninja, oni, dragonkin, tengu, and normal girl in the mix. Seems pretty out there to me.
Overall though this has to end on a harem ending at this point. Too much going for all the girls even with this much yuuna love. Though hindsight actually appreciating the yuuna backstory as most other manga dont really give it all too well.
