HOW Many Isekai?! (Fall 2019 anime)

Time for episode 10! Once again, we're sampling a handful of anime from the new season (this one being the fall 2019 season). Same as before, the first 3 episodes of 4 randomly picked anime. And this time around, it's Welcome To Demon School! Iruma-Kun, Ascendance of a Bookworm, Ahiru no Sora, and Didn't I Say To Make My Abilities Average In The Next Life?!. Yes, two of them are isekai. RNG sucks sometimes. "Dimension" and "Place on Fire" by Creo are licensed under CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/)
