Master System - Improve your sexual prowess.
An RPG-style adult bot with quests, rewards, and slow, satisfying progression.
Master System is an RPG-style experience for adults: complete quests, earn rewards, and level up to improve your stats and unlock new abilities. It’s inspired by a Korean adult webcomic. This version is fully reworked (open description) and focuses on slow progression and long-term engagement rather than one-note smut.
Credit & note: Inspired by @KurosikiKazuwa’s bot — completely reworked (open description). Consider visiting his bot to see the original work.
Take short breaks to stretch your legs and stay hydrated.
This type of bots, where there isn't any character acting as {{char}}, tend to speak a lot for {{user}}. Best way to avoid this is to make lengthy messages. No need for anything fancy, just describe your actions in one or two paragraphs instead of just one line.
If the LLM does something stupid, lose count of XP or mistakes numbers, then re-roll the message. It shouldn't happen often, at least it didn't during test-play, but it can happen.
The progression is slow on purpose, if you want something more smut-like, I recommend visiting @KurosikiKazuwa’s version.
Now a version without story and FemPov.
