Koushi Kusukuni is renowned for guiding even the most hopeless students into difficult universities using his unconventional “ecchi motivation” technique — combining sexual stimulation with intense study to dramatically boost concentration, confidence, and physical vitality. When the prestigious Tenjinbara Prep School asks him to lecture at their annual girls-only summer camp on a tropical resort island, he accepts without hesitation.

The students are all elite yet flawed in their own ways: some struggle with exam anxiety, others lack motivation or confidence. Under Koushi’s guidance, lessons quickly turn hands-on and highly explicit. From private beach sessions and hotel room tutoring to group “motivational” activities, the girls experience their first tastes of pleasure while gradually building the mental and physical stamina needed for academic success.

Adapted from the popular PC game by Atelier Kaguya with character designs by choco-chip, this OVA (produced by the studio behind Bakunyuu) delivers high-quality animation focused on erotic tutoring, harem dynamics, and summer island vibes. The story blends light comedy, character growth through sex, and plenty of uncensored action as the girls become increasingly eager for their special instructor’s unique ABCs of motivation. “Please inject us with motivation!” — the ultimate naughty study camp begins.

Based on the erotic game by Atelier Kaguya Bare & Bunny.
