I Don't Like You At All, Big Brother!! Vol. 12

I Don't Like You At All, Big Brother!!, known in Japan as Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne!, originated as a light novel series written by Daisuke Suzuki before being adapted into this manga series illustrated by Kouichi Kusano. This twelfth volume serves as a continuation of the romantic comedy narrative, focusing on the complex domestic dynamics between a long-separated brother and sister who reunite under the same roof. The series gained significant traction during the early 2010s, riding the wave of popularity for 'imouto' or younger sister-themed tropes within Japanese pop culture.

The English-language publication of this volume by Seven Seas Entertainment reflects their commitment to bringing niche light novel and manga adaptations to Western audiences. Kusano’s character designs are hallmark examples of contemporary light novel aesthetics, prioritizing expressive, stylized features that emphasize the comedic and sentimental tone of the story. Upon its release, the series was received primarily by fans of the harem and rom-com genres, who appreciated the lighthearted, albeit unconventional, relationship humor presented through Kusano's clean and accessible panel layouts.
