One angle I haven't seen discussed much is the fics that treat Yoru's and Denji's relationship as a bizarre, symbiotic partnership instead of a romance. The best ones for me are the stories that lean into their fundamentally broken nature. They’re both weapons of war, in a way, and the most compelling narratives explore the horror and dark comedy of that. I'm thinking of that one fic where Yoru tries to 'collect' Denji as a weapon and he just doesn't get it, leading to this weirdly mundane cohabitation.
These fics often completely sideline the expected romance beats. The 'ship' feels incidental, born from proximity and shared trauma rather than any healthy attraction. It's a mess, but a fascinating one. The dialogue in the good ones is always sharp—Yoru's brutal pragmatism clashing with Denji's chaotic, survivalist nonsense.
I'd skip anything tagged 'fluff' or 'domestic bliss' for this pair. That misses the point entirely. Look for tags like 'mutual manipulation', 'unreliable narrator', or 'psychological horror'. The tension isn't will-they-won't-they; it's more about whether they'll destroy each other or the world around them first.
