Onii-chan no Koto Nanka Zenzen Suki Janain Dakara ne!!

Shortened to “OniSuki,” this over-the-top comedy follows Shuusuke Takanashi and his possessive younger sister, who harbors strong (and questionable) feelings for him. Her antics push sibling boundaries, weaving absurd humor into the fabric of daily life. A slew of rivals, misunderstandings, and teenage hormones flood the story with comedic tension, exposing how young love can be both clumsy and endearing. Beneath the silly premises, the show also pokes fun at family relationships and the messy wonders of adolescence.
