Harem, but it's a good harem with unique characters with a masterful mix of drama, romance, and action. Ending was also good. Couldn't have asked for a better story so 5 stars from me.
Finished it 2 to 3 years ago I think. I really like how it started but damnn was that ending disapointing as FUCK! It wasn't the same girl anymore and I hated the fact that he ended up with Kuro, a bland basic girl with absolutely no character development. I just hated it towards the end, it flopped so hard on its face !
