It's pretty impressive what you can do with Illustrious, using just 3 short comic pages of a one-shot. This character (+ a small bit of style) is from a certain one-shot comic from Ie.

It doesn't seem as though she had a name, but I thought Akari fit well.

It's another one of the loras that's more on the side of an experiment, but it turned out really well in the first run, so I'll go with this for now.

Trigger word for the character is: ak@ri_chara

Trigger word for a general comic influence is: r@ram_kom (it changes the style slightly)

It knows two outfits to some extent, the shirt with a pinafore dress, and the blue pajamas outfit.

You can also use "ie \(raarami\)", which is natively trained in Illustrious already, or use one of the (I believe there's two of them) loras for the style of the artist to reinforce the feel.
