About "Imouto wa Siscon Ani ga Mendokusai"
Yui Hasegawa is a somewhat unremarkable high school student
who has a brother, Yu, known as the school's coolest, academically and athletically gifted ikemen.
The two siblings look so different that rumors of discord circulate between them, and Yui, who has a "perfect brother," has her own worries.
That is...
Her talented and beautiful brother is actually a severe siscon...!
A hilarious home comedy featuring polar opposite siblings: a brother with extreme gaps and a sister with salty responses!
Volume 5 of the comic will be released on January 30, 2026 (Friday)!
