After catching up to the latest chapter, I can vouch this manga is a balance between heart warming and fan service.
Kanan-sama features a new twist on the classic trope of romance between demons and humans.
She is so used to "feeding" on humans she has no experience in the natural love aspect.
This manga is somehow managing to work in between pure innocent love and fan service?
Sometimes the fanservice and logic could be a bit..excessive, but this can be forgiven as every single manga chapter contains high quality art.
I would even say the quality here is better than the majority of other titles around the manga world.
This is an entertaining read, why not give it a try?
