What do we know about MARRIAGETOXIN Season 2 so far?

Hikaru Gero’s hunt for a suitable partner for marriage isn’t over yet! He and Mei Kinosaki will continue to hunt for the perfect wife while also delivering some top-notch action in the second season.

Other than the January 2027 release window, not much else was revealed about season 2. However, as the first season concluded with the manga’s Beast User Arc, it’s likely that the second season will put the Teruaki Arc into full gear. With the Gero family trying to foil Hikaru’s plans, he and Mei will have more powerful enemies to fight off. 

The original manga author Jomyaku’s comment for the second season states (machine translation):

Marriage Toxin is getting a second season! When I first heard about it, I was like, “Seriously!?” and was so surprised... I'm incredibly grateful... No amount of gratitude is enough, but it's all thanks to everyone who supported us! Thank you so much (so much...)!! I can't wait to see Gero, Kinosaki and the others again, thanks to the anime staff who have made the original work 1000% more amazing, and the voice actors who have brought the characters to life with their incredible acting skills!! Furthermore, in the second season of the anime, even more charming and outrageous characters will be added and run wild in all directions... so please look forward to it!!!!

The original manga illustrator Mizuki Yoda’s comment for the second season states (machine translation):

Thank you so much for deciding on a second season! This is all thanks to everyone who always supports us. I love the opening and ending themes from the first season and have been listening to them ever since, so I'm really excited to hear that they'll be produced for the second season as well! Many of your favorite characters will be appearing in the second season, so I hope you'll look forward to it!

Poison Master Hikaru Gero is about to take on his most challenging assignment yet—getting married! But after training his entire life to become one of the world’s deadliest assassins, Gero couldn’t be more clueless when it comes to the art of dating. Thankfully, marriage swindler Mei Kinosaki knows everything there is to know about love, and together, this unlikely pair is going to do whatever it takes to get Gero hitched—even if they have to take on the entire criminal underworld in the process!
