Rosario to Vampire Capu2

Every once in a while, a much-awaited sequel to a popular anime comes out and baffles the audience with unwelcome anime-original story changes coming as a result of diverging from the original author's style and vision.

Or, in a similar vein, the IP holder decides it's time to resurrect a story that was by all means finished (or close enough to it) with a completely unnecessary sequel or side-story that fails to live up to the original and makes the whole franchise worse just by existing. Even worse if it retcons the original to invalidate a major dramatic plot point just so that the sequel could happen.

In either case we're left with something that many fans will plead you to pretend it doesn't exist, and honestly... you should probably listen to them.

This list doesn't include manga/LN adaptations that started diverging from the original storyline already in their respective first (or only existing) seasons.

This list also doesn't include sequels that people actually asked for but they ended up horribly made (i.e. Berserk 2016, One-Punch Man S2).

It obviously doesn't include sequels that adapt bad source material without changing it (e.g. Food Wars S4 onwards); while a caring adaptation team will sometimes try to remedy the faults of the source, it's not expected of them to do so.

Fate and Gundam franchises aren't included simply because I just can't pick anything in particular from their enormous(-ly bloated) universes as an example of something unnecessary. You aren't losing anything by ignoring most of them.

This list constitutes my personal views and stances. If something isn't on it, it likely means I haven't seen it or don't have an informed opinion on the matter. Feel free to shoot me suggestions via DMs, but make sure you have a convincing argument if it's not something that's already on my main manga/anime list. I don't promise it'll end up here, but I will consider all suggestions.

Some kind of romantic relationship between human and non-human (yokai, vampire, ghost, alien, ...)

It's trash harem but its sum of it is gud and underrated

some of it is ecchi so be a little picky

a small collection of notable vampire animated series worth experiencing

Adaptations that share nothing with their source material but the title, some characters' names, and maybe even the premise, to the point you could change the title and no one would tell it's an adaptation. Remakes/reboots/sequels/localizations also included.

List of anime that differs from its source either because it caught up with the manga and they had to create an original ending or just because the producers wanted to.

I'm accepting sugestions

The most Ecchi of the Ecchi that are mostly vanilla.
