Takizawa Kei

I was accepted to work at the game company that I admire SGO (Sister with Great Onii-chan)! The job given to myself, Keita Majima, a high school student who got such a miracle is "Rental Onii-chan" to make the best sister character! It's a sister-sister contract romantic comedy story full of affection between myself who loves younger sisters and the girls who want to be my younger sisters!

Kazuma, a highschool student who loves eroge, has been confessed to by the honour student and beautiful girl, Misaki Honoka, who's the school's prodigy. What's more, Honoka had declared that she would try her best to become a "heroine" that Kazuma likes?! "Can you… train me?" What kind of eroge is this?
