## Season 1

### Soundtrack

"Kill or Kiss" being the opening of Marriage Toxin is pretty good. It's sufficient.

The ending song? Forgettable. I didn't really like it. Pretty skippable to be honest.

### Thoughts

Marriage Toxin is an anime about the trials and tribulations that Gero, a Poison Master, has to go through to find a suitable bride so that his sister can be a lesbian. That concept on is already pretty good, and it's also executed quite well.
