This anime is not an anime.
You know those romance/visual novel video game walkthroughs on YouTube that show you what happens when you pick all the best romance options for love interests? That’s what this is. They don’t even try to put in an actual viewer stand in character or stick to one LI per episode. It’s like they’ve literally just spliced all the relevant cut scenes together without attempting to make an actual anime.. It’s not subtle. Or particularly well done.
If you’re interested in the game King of Prism is based on, feel free to check it out. Otherwise, you’re not missing much if you skip it.
