Ah yes, my favorite isekai, “That Time I Unlocked Magic Powers By Flirting With My Sister”. In all seriousness, though, I did find it interesting that they chose to tell an isekai story from someone else’s POV - it felt refreshing and gave the anime a bit of a head start in a very crowded field. However, the plot seems pretty bland and this episode was overwhelmingly devoted to setting up an incestuous ship, so uh, that goodwill only goes so far. I give the premiere a 2/5.
