マリッジトキシン [Marriage Toxin] #14

by Joumyaku, Mizuki Yoda (Artist)

Gero may be a master assassin, but he’s not exactly killing it in the romance department! Can marriage swindler Kinosaki help him find true love?

Poison Master Hikaru Gero is taking on his toughest assignment yet—getting married! Gero couldn’t be more clueless when it comes to dating, but thankfully, marriage swindler Mei Kinosaki knows everything there is to know about love. Together, this unlikely pair will do whatever it takes to get Gero hitched—even if they have to take on the entire criminal underworld in the process!

Gero and Protector Chinatsu Akakura are partnering up for yet another job, and this time, they’re in real trouble! When their seemingly meek client turns out to be the former head of the Iron Clan, Gero and Akakura quickly realize that this job is much bigger than either of them ever expected.

I liked the Iron Clan boy and it was sweet to see how things wrapped up with Nabe and Gaku, even though she wasn’t my favorite.

VERY nervous to see where things go with Gero’s mentor 😳 He’s terrifying.

I am lost & confused as to what is really going on but I’m excited for the next volume. Do kinda hope it ends soon though, really feels like we have been dragging our feet.

We get to close the story of the iron clan and it’s cute. But the poison clan was involved and that’s haunting. Plus visiting them for the end of the volume has me on the edge of my reading chair. It’s such a fun story and I wish I didn’t have to wait for the next volume. Honestly wish I could give it an extra half star because it really is that close to being another perfect volume to me.

Okay, I have questions and judgement (for yee ol' grandma). Why she gotta be so creepy and why is the doll/other family member interfering?

Outside of the creepiness of his family, we get so many cute moments. Gero gains a new friend/rival, meets a legend and fulfills her last wish AND he gets to take cute ass "pretend" wedding pics with our girl. Then shit hits the fan and Gero does not back down. It's something about seeing him threaten his own blood over Kinosaki that had me cackling.

If Tengen Uzui can have three wives, surely Gero can have like 5.

Thanks to Edelweiss and Viz for the DRC.

4.5/5 stars

The Nabs and Gaku story ending made me emotional, and I love Kirito quite a bit. He finally has his rival with Gero. Also, the chapters with Gero and his grandmother? Mwah, him showing his growth and threatening them if they hurt Kinosaki again was wonderful. But I’m only stressed now because of the ending

“If you ever lay another hand on Kinosaki, you’ll have to answer to me.”

Um. Which could mean nothing.
