If I got a penny for every time I watched an animated commercial by this company I'd have 3, which isn't a lot but its weird that it happened thrice. This isn't an anime nor a trailer for the actual movie, its a commercial with a story that takes place within the summer ghost universe. The animation is good and the story is alright I guess but I find it a bit ironic that this is advertising for a cram school while the main movie portrays cram schools as a evil that is extinguishing all sense of creativity. 6/10 TLDR: Watch it if you want to seea commercial with a story from the summer ghost universe
