Summary

I never wanted older sisters. I wished I could be an only child. Born as the youngest of four siblings, my life was an everyday struggle, surrounded by three demanding, selfish, and capricious older sisters. They treated me like a slave. The eldest, a kendo practitioner, tortured me with grueling training sessions whenever she had the chance. The second sister, looking sweet like a sugar candy but with a personality as fiery as a habanero, was a magazine model. Then there was the third sister, a NEET in the making, who flatly declared that she would rather die than work, and used me as her personal assistant. One day, I vowed to make them regret their actions. With revenge in my heart, I clung to the last hope offered by a dubious fortune teller, who introduced me to the power of hypnosis. "From now on, your sisters will be hopelessly in love with you!" In that instant, my three sisters transformed into the ideal older sisters who adored me above all else! ...But what the heck is going on!? Why are they coming on to me so aggressively!? It turns out my sisters were incredibly susceptible to hypnosis. They revealed their hidden, embarrassing fetishes and began to pursue me with fervor. I was left flustered and overwhelmed by their advances. Wait a minute. I only wanted a little payback, but this is way worse than before!?" [Translated from the official website]
