▼STORY
Principal Sarunaga Osumitsu of Kanikko Academy is furious. Compared to his hated rival, Principal Inukai from another academy, his ranking in the “Principal Rankings” is inferior.
The “National Principal Sexual Education Guidance Association” (aka the Principal’s Association) has 4,502 principals nationwide as members. To improve your Principal Ranking, conducting “special guidance” to students according to the rules established by the association and submitting “recorded media” of it are absolutely essential.
To raise his ranking this time, Sarunaga sets his sights on Kozakai Mihane, a female student with high facial attractiveness, well-proportioned figure, and—importantly—already has a boyfriend.
Calling her to his office, Sarunaga conducts unrestricted special guidance (sexual harassment), and she cannot resist.
Why? Because he is—
“The Principal!”
▼CHARACTERS
・Sarunaga Osumitsu (Principal of Kanikko Academy)
Known for giving abnormally long morning speeches that cause students to faint (continues anyway). A problematic principal who gropes female students indiscriminately. However, it appears nothing is forbidden when “you’re the principal.”
・Kozakai Mihane (Kanikko Academy Student)
Bright and optimistic. Despite being in exam preparation period, she’s constantly with her boyfriend. She and her boyfriend Toshiyasu frequent arcades and karaoke after school to relieve exam stress. Their relationship is good.
・Asagishi Toshiyasu (Kanikko Academy Student)
Mihane’s boyfriend. Unlike her, he has excellent grades, but reluctantly spends time at arcades accompanying her. Worried about her poor academics and uncertain college prospects.
Editorial Review
A workplace power-abuse fantasy wrapped in bureaucratic absurdism, *Because I’m the Principal!* occupies a specific niche within the NTR and sexual harassment simulation space—one that leans heavily into role-play mechanics and 3DCG animation quality as its primary selling points. The concept of competing principals conducting “guidance” as a ranking system is deliberately tongue-in-cheek, positioning harassment as gamified institutional sport rather than realistic scenario.
The work’s distinctive appeal lies in its animation-first design philosophy. Over 150 3D toon animations indexed to body-part interaction creates a click-and-discover loop where player choice directly determines animation progression and parameter outcomes. This mechanic-driven approach means replay value hinges on experimentation rather than narrative branching—you’re optimizing animations across different interaction sequences. The large-breasts aesthetic and consistent 3DCG rendering suggest production investment, though the synopsis cuts off before detailing story depth beyond the premise.
The NTR element here operates in a specific register: the student character has a boyfriend, which anchors the betrayal component, but the framing emphasizes the power-dynamic transgression over emotional elaboration. This is simulation-first design, where narrative context serves mechanics rather than vice versa. The “Guidance Level” progression system transforms coercion into unlockable content tiers—a design choice that makes the appeal explicit and mechanical rather than atmospheric or psychologically complex.
This will resonate most with players seeking animation-dense, mechanic-driven sexual harassment role-play with minimal narrative ambition and explicit power-dynamic appeal. If you prioritize animation variety and click-based discovery over dialogue-heavy scenario construction, the 150+ animation count justifies exploration. Players wanting emotional complexity or narrative sophistication should look elsewhere; this is pure mechanics fantasy.
A technically competent animation simulation for its specific audience, though one-note conceptually.
