I only started the series at the end of the hype train. From what I gathered from the snippets of texts from the source material vs the animated scene, source material > anime still wins in the amount of detail. If it's just based on the anime, some parts just comes off as plot armor given how conveniently left out some details. The extent of how much they could purchase with their points, you think someone like Ayano would have just purchased someone's dirty backstory instead of going to some mental hoops.
