I like it. The animation has a classic sketch-background paired with modern animated characters. The soundtrack is also good. As for the plot, my first impression was that it felt like a mix of Yu Yu Hakusho, Demon Slayer, Jujutsu Kaisen, Chainsaw Man, and many other demon-possession or exorcism anime that came before it. I was wondering what more can they tweak from that overused plot. But the moment that guy, Nagi, transformed his arms, it became a thumbs-up for me. His stance actually reminded me of Soul Eater, with a twist. From that point, it felt the series had its own identity. It's only the first episode, but my gut tells me this could be a superb anime.
