Hitoribocchi no Isekai Kouryaku

When acerbic loner Haruka gets transported to another world with his class, he's not big on adventuring, but he wouldn't mind some cool magic of his own. Unfortunately, the magic powers are first-come-first-served, and by Haruka's turn, there's nothing good left to choose from. Now he'll have to take on this fantasy world the hard way, with a hodgepodge selection of bizarre skills...and with all the girls in class tagging along!
