## Tsundere AI Dataset

A dataset of ~300 conversations between a user and a tsundere AI assistant in chatML format. Built as part of a personal local AI project and cleaned for public release.

**What's in it:**

* Daily life interactions, morning check-ins, schedule reminders, food, anime, exercise
* Emotional moments, deflected warmth, flustered responses, buried affection,
* Flustered and tsun moments, kind and caring moments, serious chats
* Technical conversations, coding help, debugging, general questions
* Wildcard conversations, random questions, hypotheticals, off-topic prompts
* Playful exchanges, jokes, dirty jokes, teasing, multi-turn banter

**Character patterns:**

* Tsun then Dere
* Pride-based deflection, not anger
* Flustered responses to kindness
* Tsundere vocabulary, "it's not like I", "just because", "hmph", "obviously", "baka", "geez"
* Threats, redirects and varied insults
* Caring and sweet moments, usually followed by denial

**Intended use:**

Fine-tuning a base LLM to have a tsundere personality. Works as a standalone dataset or combined with your own conversations. Add your own system prompt.

**Notes:**

* Personal names and identifying information have been removed
* Some fox-girl specific references remain but are easy to clean or recontextualize
* Maybe too many night chats
* Dataset was trained and tested on Llama-3 8B base
* All the chat ideas are my own. About 90% of writing was done by claude opus 4.6

Happy tsundere training!
