Overview

A Teacher's Sins is a text-based RPG and visual novel for players who want a slow-burn academic setting mixed with adult sandbox play. The tone stays grounded and character-driven, leaning on personal choices rather than spectacle.

Story

As a newly hired professor at the Millennium Institute, the player settles into a school built around brilliant, difficult students. Beneath the academic routine sit hidden mysteries and social currents that the professor must navigate while building a place within the faculty.

Gameplay

Play centers on teaching duties, campus interactions, and steadily building prestige within the Institute. Through a character creation system, players shape their professor and then guide them through a sandbox of school life, using skills like stealth and social leverage to access new opportunities, relationships, and illicit dealings as they arise.

Features

Character creation lets you define your professor's identity, including options for male, female, or futa/trans protagonists
A school-based sandbox where reputation and skills open new routes through campus life
Harem-style relationship building woven into the teaching routine
Blackmail and dealing mechanics that reward riskier choices

Installation

1. Extract and run.
