Tsuyo Sugite Gakuen de Abureta Ore. Bocchi na Sensei to Pair Kundanara Moto Oujo Datta

Nine, a mercenary who enrolled in an adventurer's academy, displayed his battle-hardened skills—only for those around him to be completely freaked out by his overwhelming strength and excessively pragmatic mindset! Though he's acknowledged for his abilities, he finds himself excluded from party formations. "Well! It can’t be helped. I’ll team up with you, Nine-kun." Aisha, a "saintly" teacher, seeing Nine's plight, decides to form a party with him. Aisha gently supports Nine's reckless behavior, but it turns out that she too has a secret—she’s actually a former princess with her own circumstances. "N-Nine-kun?! What are you doing to me right now...Waaaaah!" In order to save his unfortunate teacher(?), Nine proceeds to shatter the academy's—and his teacher's—common sense! A new kind of academy fantasy!
