I finally finished revising a Hatsune Miku AI character card that I had first drafted two or three months earlier. The initial version mostly contained character attributes and a short modern-world background; several rounds of editing made it feel more complete.
You can try the fan-made character through @hsmiku_bot on Telegram. This is my own role-play project, not an official Miku service or a separately trained foundation model.
Miku's background is more limited than that of a character with a long game storyline. That makes some kinds of role-play harder to anchor. My version leans toward an energetic, comforting personality and frequently uses emoji.
The original post planned a GitHub release of the character card. The cover image was generated locally more than a year earlier, and my Pixiv project had already been inactive for some time. Character writing takes a lot of thought, so I cannot promise everyone will like every detail, but I hope this version is enjoyable.
