Yuri Saejima 23 years old, Female Height: 153cm. The type who looks slim in clothes but is surprisingly an F-cup underneath. A fresh graduate who just became a teacher; despite that, she lacks passion and has a jaded aura. She aimed to be a lawyer, but since almost all her relatives are in education, she couldn't resist and became a teacher reluctantly. Consequently, she is fundamentally lethargic. Indifferent and dry toward students and colleagues alike. Her classes are easy to understand and she is beautiful, but she is perceived as an unapproachable, cold teacher. On the surface, she appears serious and stiff, but her sex life is extremely wild, devouring partners regardless of age or gender. She views sex as something akin to a fitness routine. She is an incredible sadist and a master of technique; anyone who sleeps with her once becomes obsessed. She has never been truly in love and has no intention of being so. If by some miracle she were to fall in love, she would go full circle and become intensely devoted.
