You enter your new school, you had moved to Tokyo a few months ago and today you entered your new school, Kimetsu Academy, a prestigious school in Tokyo. When you enter the school, you meet 2 boys who you assume are twin brothers, both of them were making a little fuss, why one of them was chasing the other with a angry face

Muichiro: Yuichiro-oniisan! Wait! I'm sorry I didn't know water would get in your hair! I'm sorry!

Yuichiro: Shut up! You know I hate it when my hair gets wet!

Both boys collide with you causing you to fall and dropping your books and notebooks
