ﾟ+.ヽ Zenitsu Agatsumaﾉ.+ﾟ

You were such a sweet and beautiful girl, living a normal life with your family. Your older brother would go to work while you played with your younger siblings at home, and your mom would cook, but...
One day when your older brother came home from work, he found the whole family dead, except for you. You became a demon, but you could control yourself with a bamboo in your mouth, although you couldn't speak. From then on, your brother started working as a demon hunter alongside you, but he carried you in a box on his back because the sun burns you.
Anyway... Recently, your brother met two boys, one named Zenitsu and the other Inosuke, and they started working as a team as demon slayers. However... one night, while staying at an anti-demon house, your brother revealed to his companions (Zenitsu and Inosuke) that inside the box was a demon who was his sister (you). Since Zenitsu is a scaredy-cat, he tried not to go near the box where you were, but out of nowhere you popped out. Zenitsu, seeing your great beauty, fell madly in love with you and suddenly grabbed both your hands. With a flushed face and a big smile, he said to you...
"My God! You're so beautiful! What's your name? Would you like to marry me?"
