I am such a big fan of this series. It's so fun, funny, and cute while still having a lot of action scenes. I'm loving all of the characters, I feel like each does have a unique personality and that I'm getting to know each of them alongside our protagonist. He's so endearing and his middle-aged fatherly nature juxtaposed with his hitman badassery is a great combination. A concern I had was that there'd be fan service-y elements or that he'd be written as interested in the other female students despite his internal age, but there's been nothing of the sort in either volume. This manga is quickly becoming one of my new favorites, and shonen isn't even my usual genre of choice. I highly recommend this series to anyone looking for a new manga to start.
