I've noticed a recurring original character in ms._tsu 's posts. They frequently refer to this character as "A girl from the dream" (E.G. post #8330485 , post #8150708 , post #8097371). Furthermore, this character has some consistent details, blunt bangs, the red color, a mole on her chin, the shadow figure alongside her, and hidden words. A motif of this character seems to be hidden words, repeatedly "Unnamed", "Dream", and "Girl" like in post #8330485 and post #8318632, so "Unnamed Dream Girl" would be an appropriate name for her. Although it's a trait of the artist to hide words in their art, these three words seem applicable to the character.
I can propose this as a wiki for the tag.
An original character from ms._tsu that has red_hair, mole_under_mouth, blunt_bangs, black_eyes, and is frequently accompanied by a shadowy figure with a wide smile. She typically also has words written in the shine of her hair, typically "Unnamed" and/or "Dream girl".
If this character tag is made, it should be available for the following posts.
