Anime Like MARRIAGETOXIN
A poison master who'd rather die than let his sister be forced into marriage decides the solution is to marry a random woman himself, and then actually falls for her. The show commits to the bit: every poisoning attack doubles as a love confession, every combat scene is foreplay, every joke lands because the emotional stakes are real. You watch a hardened killer learn that vulnerability is not weakness, one terrible pickup attempt at a time.
SYNOPSIS
Hikaru Gero grew up in poison and shadows. As heir to one of the Five Great Families of assassins, he knows toxins better than he knows people. That changes when his family declares his sister must marry and produce an heir, willing or not. Desperate to protect her from forced matrimony, Hikaru searches for an escape route and finds Mei Kinosaki instead: a con artist who specializes in marriage fraud and sees through every lie. What starts as a business proposition becomes something neither of them expected. Hikaru needs a fake bride to buy his sister time. Mei needs reasons to trust someone who deals in deadly poisons. Together they navigate a world where bloodlines matter, loyalty is weaponized, and falling for your fake spouse might be the most dangerous gambit yet. It's action wrapped in comedy, murder wrapped in romance. A show that treats the absurd premise seriously while refusing to take itself too seriously. Perfect for anyone who wants their relationships complicated, their stakes high, and their humor sharp as a blade.
