Here's another series I've been reading recently, and I have to say it's quite awesome. It's hilarious. Fans of GTO and Golden Boy should surely enjoy this. Clearly intended for a mature audience, so you can tell what type of jokes will be in it. There's quite a bit of nakedness, so beware for those that find that offensive, and for those who not... enjoy.

But really, this series has some good comedy and I think the art is quite good. I don't think you guys will be disapointed.

Yataro Sarumaru, nicknamed Saru, is an ace in the locksmith trade and is obsessed with girls. This (almost) average teenager is given a hardly ordinary mission which marks the beginning of his adventures!
