Review based on personal opinions and taste:

Spoilers ahead :)


The lead characters got injuried? No problem, just hop on in butterly estate and get all your injuries healed up by skipping the story, what happened in the time we skipped? oh...well the leads were just asleep you see, and the demons being the good guys they are, they didn't do anything while that happened, they respected their privacy and planned their attacks for when they're all healed up and ready to battle, i mean sure the boss demon wants them dead but why all the rush, jeez...anyway, now that they've woken up why not get stronger by playing tag with the butterly estate triplet slaves? :D suddenly the blood shedding plot turns into bonding with the ladies, hurray.

Anyway, now we gotta go the the next bad guy, bad guy does bad things, reader mad, lead character getting beat up, reader in suspense, invoke the secret power within you, reader happy, flashback back to when bad guy was good guy, now reader sad, hop on in butterly estate for that sweet heals, train with the triplets, next to the other bad guy, rinse and repeat.

5/10, didn't hate it but didn't love it. I'm sure there's something much better to sink time in than this.
