So this is one of the best Ecchi Light Novels you can possibly find. This actually has a good plot so you can enjoy both sides. If you don't like Ecchi being the important factor in the plot, then try to get used to it or simply don't bother reading it.

The story is interesting once you get into it, slowly learning more about characters pasts and the current situation. The fights can get pretty serious at times but the tense battles cool off once the Ecchi kicks in ;)

The Ecchi parts are too good. If your thinking that letters alone can't arouse you... you are completely wrong. The few pictures and the way the words are used, it's inducing.

Is it worth reading? Of course it's worth reading, I doubt you will get bored. Btw if you watched the anime, oh boy you are going to realize how much content you missed. The Light Novel is much better but I do love the anime :3

Shit will happen. Hot stuff will happen. Even cringe might happen. It's simply a harem, ecchi, action LN at the end of the day.

Hope I helped
