Think I have a good idea on how to train characters now, this one looks really good so far.

Triggers:

Main: HokusaiPonyXL

Appearance: katsushika hokusai (fate), short hair with long locks, medium hair, purple hair, hair bangs, blue eyes, sidelocks, twintails, hair ornament,

Outfit: swimsuit, bikini, bare shoulders, white bikini, goggles, goggles on head, floral print, sash, thigh strap, jewelry, bracelet, collarbone, belt, obi, beads, red sandals

Strength: 0.8 - 1

You can prompt other outfits as well, remember to use a strength lower than 0.8

Current issues:

The katanas are a whole mess, would just avoid them, seems even Pony doesn't know how to create them properly.
