steel ball run character prompts — 15 NovelAI character tags

How to prompt steel ball run characters in NovelAI

This page lists 15 character tags from steel ball run that work in NovelAI, each with a sample image.

Every image uses the same seed and prompt, so the only difference between two cards is how well each character comes through.

Put the character tag first and the series tag right after it. The series tag helps avoid mix-ups between characters with the same name and helps keep the outfit consistent.

Example prompt: funny valentine, steel ball run, solo

When a character's name collides with another tag, the tag takes the form "name (series abbreviation)". The part in parentheses belongs to the tag, so keep it.
