漫画プラスチック姉さんから、辰姫。

素顔は素朴な美少女。戦国大名の娘で、岬から身を投げた過去がある。

ネズミファイター時よりも容姿が幼くなっている。

最近のエピソードではこの本来の姿を描かれることが多い。

サチ、菊池、山田関連のエピソードで多く登場。

negativeにmonochlome, positiveにanime_coloring,などの品質プロンプトを入れるとモノクロが出にくいと思います。

Tatsuhime, from the manga Plastic Elder Sister.

Her true face is that of a simple, beautiful girl. She is the daughter of a feudal lord during the Sengoku period, and once threw herself off a cape.

Her appearance and physique have shrunk and become younger than when she was a Rat Fighter.

She is often depicted in this form in recent episodes.

She appears frequently in episodes related to Sachi, Kikuchi, and Yamada.

I think it will be less likely to produce monochrome if you enter quality prompts such as "monochlome" in negative and "anime_coloring" in positive.
