Marriage Toxin Ratings & Reviews
- MikefIixApril 24, 2026Marriage Toxin is a wholesome action anime about the awkward poison master that needs to find a wife to secure the line of future poison masters. It's a nice action comedy, kind of like Sakamoto, with high production value and giving me enough entertainment and surprising turns of action with every episode to make me come back curiously every week for more. The author seems to have many solid ideas and so far does not rely on a single plot loop. Who will be his final choice? Nobody knows but sometimes answers to our questions are closer than we think... I hope.
