Series that cause what I call "Twisted euphoria"

Series that make me ecstatic to be alive, grinning from ear to ear or laughing like a maniac, despite (or rather, because of) how f***ed up parts of them are, in conjunction with how not-f***ed-up other parts of them are.

Cute girls killing people with a smile,
magical girls committing sudoku,
beautiful worlds full of haunting ghosts,
a shounen-style tournament full of huge perverts, etc.

As an example of what I mean, Doki Doki Literature Club had me smiling from ear to ear the whole way through. Even moreso in the second half than the first.
Fujimi Lovers is a perfect example in terms of manga.
The Mesmerizer Miku song is another good example.
Also, if you've ever watched Murder Drones or The Amazing Digital Circus...
The "Twisted Euphoria" feeling I'm talking about is pretty similar to how Baio Rin from 100 Girlfriends reacts to violence.

The ones closer to the top of the list are generally more likely to cause this feeling, and the ones at the very bottom (Saya no Uta and below) are the manga/novel versions of other media that would be on the list, instead, if it was allowed.

The series on the list are based on my subjective experience, so some other series that could cause the feeling might not be on here, like Madoka, Made in Abyss, or some others.
