Saimin Torotoro Operation ~Innai Bikyonyuu Hokan Keikaku~

The protagonist is a psychiatrist.
Everyday, he is oppressed by the females in the hospital.
One day, he comes across a hypnosis technique.
Using this, he can do any to the ones who harass him, the mature director, the genius doctor, the cheerful nurse and the cheeky student.
And so, his lewd retaliation begins.
