It's a decent, short Harem Manga. The MC finds a Knife that makes him leader of all ninjas and random Girls come for him to retrive it. They all get naked for one reason or the other, hilarity ensues. The Manga is quite short (15 Chapters) and is rather straight to the point - girls getting naked. While there is a backstory (the Ninja leader thing) that's just an excuse for some omnious, faceless Ninja leader to throw more and more girls at MC who just keeps them in his harem. If you like Ecchi Harem stories, this is the Manga for you. If you don't... then don'tread this.

I personally enjoyed it. 7/10
