Just terrible. It's over used trope after trope. The generic harem of bro-con sister, childhood friend, the ojou-sama (princess), the man-hater, etc. The MC hides a huge power that everyone looked down on as weak. Need I go on? It's only a matter of time before he accidentally falls in the princess's panties, unintentionally walks in all of them bathing, etc. There is literally nothing that makes this stand out from any other harem and worse, it's poorly written and drawn to boot.
