This is another manga written by ONE and drawn by Murata Yuusuke, and just like One Punch Man this manga is wonderful. The story is a comedy one-shot that follows a young man new to the school. He accidentally finds out the secret of a classmate, a girl who fights monsters with mechanical weapons. She is observed and supported during her fights by her fan club, composed of male members of her class, but has no idea that there is anyone who knows her secrete. The young man helps the fan-club help her and give her the confidence she needs to continue fighting.
For such a small one-shot, the characters are well written and extremely interesting. The story really is a unique take on magical girls, and ONE is just a great writer. He has a great imagination and really takes cliches to the next level. I highly recommend this manga.
Sorry about how short this post is, but I really feel like this manga is worth checking out. Go now go!
