An Eroge-induced epiphany leads Hyoudou Issei down a path of hard work, excellence and extreme degrees of trauma suppression. Add to that a grumpy old dragon, an overpowered sacred gear, a frisky succubus and munchkin-worthy tactics that put the capital P in "Power Creep", and you've got yourself a nice mess. Oh, and there's also devils, and angels, and stuff. (Cover by Yutaku)
