Taiyo Kisushita

Taiyo Kisushita is the new major antagonist of Rosefell. Her only known relatives that are alive are her younger cousins Yukina Payton and Yuna Payton.

Appearance
Taiyo is a short yet slender woman with long black hair and bright yellow eyes. She often wears a dark, lesser saturated colored shirt, with a dark purple skirt. She also seems to wear pink leggings, however, we have not seen her in fully colored full body so we are unable to tell. It is unknown what shoes she wears.

Personality
Taiyo is a bitter person, who is not very open-minded. She believes that monsters are a threat to humanity, even though it was pretty obvious monsters are no match for humans, meaning she must be a person who will stick with her ideas even if they're false. She also could be quite violent. She also has a pretty bad temper.

Before The Events Of Rosefell
Not much is known about Taiyo's past, although she seemed to go to the same school as Rose, and if so, she likely knows about Rose's suicide due to her asking Rose how it was being dead in chapter 8. It is speculated Taiyo had a friend named Ella who committed suicide an unknown amount of time ago due to a short comic LittleGhostlyRose made a month or so ago |.

Chapter 8: Anti-Monsters
Taiyo was first seen at the very beginning of this episode, where she barges into the City Council room without permission, interrupting the meeting and irritating Yukina. She then begins to rant about monsters being dangerous as Yukina keeps claiming them as false several times. Soon enough Taiyo asks her "associate", Courtney, to give a petition to ban monsters from the city to Yukina and Yumiko, and after she does, Yukina quickly says no to it and that if the city truly wants monsters out of the city, that they'll vote in the City Vote next week. Taiyo then storms out furiously and drags Courtney with her. She's last seen in her presumably base as she prepares a plan to get monsters out of the city.

Yukina Payton
Yukina and Taiyo are cousins, and they seem to not get along very well for unknown reasons.

Rose Elizabeth Violet
Rose and Taiyo seem to know each other, however, they also seem to hate each other, although Rose gets very nervous around her. Possible reasons could be Taiyo's motives since its obvious Taiyo is very much so capable of physically hurting since she has quite the temper.

Trivia

 * Taiyo's name in Japanese supposedly means "Sun Kissed" although it could be slightly off, and if it is off, it would be funny to see Taiyo get ticked over it.
 * It's unknown if Taiyo's parents are alive, although if Rose's mother is alive, Taiyo's maybe too.
 * Frisk is a minor threat in terms of Rose and Sans' mental health if compared to Taiyo.
