New Series on Manga UP!: "Cool-Blooded Noble's Marriage Rejection Record" Started on June 17

One of the closely followed manga platforms in Japan, Manga UP!, is hosting a brand new romantic comedy series. The manga titled "Cool-Blooded Noble's Marriage Rejection Record" (Japanese: 冷血貴族の婚約拒絶録~オレは絶対に、結婚などしない~) by author Kosuzu Keiichi and illustrator Tōju Eru officially began serialization on June 17, 2025.
At the center of the series is a young man, heir to a noble family. This aristocrat resolutely rejects the countless arranged marriage proposals he receives. One day, he meets a stubborn young girl who is determined to marry him by any means necessary. At this point, a 'love rejection battle' begins between the two. The story, blending emotional conflict, clever dialogue, and humorous elements, offers a fresh take on the classic 'hero fleeing marriage' theme.
Kosuzu Keiichi is an author who has previously made a name for himself in various light novel projects. In this manga adaptation, he explores the tension between noble family traditions and individual freedom. Illustrator Tōju Eru is known for his character designs and expressive drawings. The duo will bring readers together with weekly chapters on the Manga UP! platform.
Manga UP! is known as Square Enix's digital manga application and has previously hosted popular romantic works such as Kaguya-sama: Love is War and The Quintessential Quintuplets. This new series follows the same line, appealing to fans of both romance and comedy. Reactions after the first chapter are eagerly awaited. The direction the series will take in the coming weeks, especially regarding the development of the 'anti-marriage' protagonist, excites readers.
