Tired of the same old romance tropes? Strap in for a high-octane adrenaline rush where finding a soulmate is literally a matter of life and death. Marriage Toxin, also known as Marriagetoxin or the original Japanese title マリッジトキシン, takes the concept of a dating coach to a lethal new level. We follow Gero, a poison-using assassin from a legendary clan of hitmen who has spent his entire life in the shadows. He is a master of the kill but a total disaster at conversation, convinced that love and marriage are simply not in the cards for someone with blood on their hands.

However, the stakes skyrocket when his clan issues a chilling ultimatum: find a wife and produce an heir, or they will force his innocent younger sister into a dark and horrific fate to preserve their lineage. At his absolute breaking point, Gero encounters Kinosaki, a brilliant and flamboyant marriage swindler who was originally his target. Instead of completing the hit, Gero strikes a desperate deal, recruiting Kinosaki to navigate the treacherous waters of romance. Together, this unlikely duo embarks on the world’s most grueling battle for marriage, facing off against eccentric rivals and deadly foes in a quest for true love. With its breathtaking art style and a perfect blend of high-stakes combat and genuine heart, Marijji Tokishin is a must-read series that proves finding The One is the toughest mission of all.
