"Male-based Futanari Femboy 'Nishin-chan'" From the time I was born, I was a genuine younger brother, Nishin-chan. However, I learned that older brothers will become extinct a hundred years later. "If there are no older brothers, I can't continue to be a younger brother!" Nishin-chan decided to keep increasing the number of older brothers and sisters in order to stay a younger brother. Thus, Nishin-chan was born on the Internet. "Future brothers and sisters, wait for me ♥ Let's do lots of pleasant things...♥" -------------- Nishin-chan is a "metagender (metamorphosis gender)".
The genitalia will transform as the older brother or sister wishes. It can become a hermaphrodite or just a vagina. (Though it's not implemented in Krosis, it can also be only a male genital or without any genital)

The reason I'm a "male-based futanari" and "femboy" is because the development of my throat and musculature is male-oriented.
Thin scapula and slightly muscular muscles, on the other hand, a somewhat fat bust, a feminine face and gestures, etc. I'm waiting for brothers and sisters who will appreciate the charm of the "twilight of gender"!
