Marriagetoxin | GOGOAnime

Synopsis:

For centuries, the Poison Masters have perfected the art of killing. Among them, the Gero family stands as one of the five most powerful Master families, possessing unparalleled skill and influence. Hikaru Gero, heir to this sinister bloodline, lived his life in the shadows of the underworld, far removed from love and marriage.

However, to ensure the Poison Masters’ bloodline does not die out, the Gero family patriarch announces that Hikaru’s sister will be forced to bear an heir. Soon, Hikaru crosses paths with Mei Kinosaki, a shrewd matchmaker who also happens to be his target. Determined to protect his sister and resolve the succession issue on his own, Hikaru makes an unexpected request: he asks Mei to help him find a husband.

“…It’s the first time anyone has ever proposed marriage like this.”

And so, with the treacherous matchmaker Mei as his mentor, elite assassin Hikaru embarks on love’s most difficult task. His goal? The ultimate wedding. An unlikely pair—an assassin and a marriage con artist—embark on the world’s most challenging mission of love.
