I enjoyed both and Isekai Cheat Magician, too. That one started out with the most promise but the storyline kind of petered out. Enjoyable, but nothing special. Retry was quite enjoyable, poked fun at itself a little and had some great characters, but the way they ended it(which was really AFTER the credits) flat out annoyed me. Quit watching at the credits on episode 12 and you'll probably be happier with it unless it's already green lighted for season two. Like i said, Arifureta started out rough, but it got better and better. Not sure if it's going to be an ongoing series, or if they're going to wrap things up next episode, but there will at least be an episode thirteen. I can see it going either way.
