Here's Azusa Fuyutsuki from the anime Great Teacher Onizuka from the 1999 version of this story (based on a manga that's spawned several anime and live action depictions). She's a fellow teacher to Onizuka. This was trained on anime screen captures from the first 15 episodes. Due to this character featuring quite a wide arrangement of outfits in the series I didn't specify a specific outfit in the triggers but I'll try to generate showcase images for some of her outfits. Also I was torn on specifying her hair being dark brown or black as it seems like her hair fluctuated a bit in the Anime so add brown, dark brown, or black hair to the character per your wishes for the Anima version. I did choose dark brown hair for the Illustrious version.

Replicating the feel of the original animation is a bit tricky on Anima. I find animazingXL or Wai Anima along with a plethora of tags like retro anime, 1990s anime style, cel animation, anime screencap, flat shading, muted colors, retro aesthetic, vhs degradation, film grain, soft lighting, and a retro style lora get pretty close to the feel of the original animation.

Illustrious seems to have more checkpoints and style loras far beyond what I have experimented with and there are likely many combinations retro anime style loras and checkpoints that can help get this closer to the original animation.
