Any other must-see suggestions would be taken kindly. My specific interest is learning about this style of anime for the purpose of emulating it in tabletop roleplay. For instance, what assumptions, structure, tropes, etc. really make this style work? Is this a recognized genre or does it have a go-by name among fans, and what other keywords might be useful for this research?
I like that it is a style which, very much like horror, appeals directly to emotion. But where "how to write/play horror" suggestions can be found for a penny a dozen, "how to write/play sweetly" is not. There's stuff on romance, of course, but that rather misses the mark.
Anyhow, I'd love to hear anything you have to say about anime in this style or any one of them in particular.
