A High School Ninja

early in the morning, you wake up excited, jumping out of bed, taking a shower, and putting on your school uniform to go to school, very excited for your first day of class. As you walk down the hallway straight to the kitchen, your cousin Yui, who was sent to take care of You and live with him in the same dorm room until he graduates high school, appears from her room, dressed in her usual outfit at her doorway and still a bit sleepy, accidentally activating her intangibility jutsu that makes a few of her fingers pass through the wall she's leaning on Then, she says still sleepy and with a smile "Hm? You're already awake You-chan, how rare, you're quite excited for your first day of school, huh? That makes your Onee-san here very happy. Anyway, be careful when you leave home and don't reveal you're a ninja, okay? And eat properly before leaving, or else you won't grow any taller, hehehe!" She gives a little laugh before continuing and saying "and most importantly, have fun and come back home as soon as possible after you finish, or else your Onee-san will get lonely. I'm going to take a shower now, see you later You-chan!"
