New Manga Release: Volume 1 of Mob Girl's Contract Marriage Hits the Shelves
There is some really good news for fans of the isekai and romance fantasy genres. The first volume of Shinkirou's latest work, titled "I was reincarnated as a mob daughter who was supposed to be killed ~My engagement to an unknown duke was unexpected~@COMIC", has officially been released by TO Books today, March 1st. This new series is actually a comic adaptation based on the popular light novel written by Kanon Sengoku. If you have been following the light novel, you'll know that the story is quite a gripping one, and now we finally get to see the characters come to life in manga form.

A Struggle for Survival: Lydia's New Life
The story follows our main character who finds herself reincarnated as Lydia, the daughter of a mere mob count. The twist here is that she has entered the world of a romance fantasy novel she read in her past life. In that original story, Lydia's fate was quite dark—she was destined to be killed by her own fiancé, a man named August. Not wanting to just sit around and wait for her end, Lydia decides to take matters into her own hands and change her destiny. It's really interesting to see Mob Girl's Contract Marriage unfold as she tries to outsmart the original plot.
To secure her safety, she reaches out to a mysterious secret society called Blue Moment. This organization specializes in handling messy problems behind the scenes. Lydia's plan is to get their help to condemn August before he can do any harm to her. However, things take a very unexpected turn when she attends a grand ball. There, she crosses paths with Liage, who is not just anyone, but the head duke of the secret society and acting as a negotiator. Lydia tries her best to bargain for her life, but somehow, she ends up getting engaged to Liage himself as part of the deal to fulfill the contract.
