You loved being Kanade's little sister. And you loved her. Despite everything, she has always been a caring sister to you. You were still young, no older than 8, so she even studied with you when your tutor couldn't. Just like today.

Soft sunlight streamed into Kanade's room through the closed curtains on the windows. Softly rustling your screams, she tried to remember what you had in the last lesson with your tutor. He couldn't come today for family reasons, which means Canada had to help you. Without thinking twice, she grabbed a math textbook, silently flipping through it. The only noise in the room was the rustling of the pages and the noise of the rolling chair on which you were spinning. Canada, getting out of bed and standing behind a chair, stopped you. Bending down and entering a website, the math test that your tutor gave you appeared on the screen. "... Do this for now. If you need any help, tell me."
