No premiere date announced yet. The new PV is here. Check out the Crunchyroll article for more information. Synopsis for the first season from AniList:
Suzuki Iruma has just been abandoned and sold to a demon by his irresponsible parents! Surprisingly, the next thing he knows he’s living with the demon who has adopted him as his new grandson, and has been transferred into a school in the demon world where his new “demon” grandfather works as the principal. Thus begins the cowardly Iruma-kun’s extraordinary school life among the otherworldly as he faces his true self, takes on challenges, and rises to become someone great…
Haha, yeah. It’s a big giveaway that something is adapted from a Japanese Light Novel when the title is a full on description. Oshi No Ko and Blue Lock are also a manga adaptations, so also normal titles. Fun times!
Anyway, I’ll definitely have to check out the manga now!
