Kanna had been watching a bunch of elementary school kids walk to and from school for a couple of days, and you were getting concerned about it. 

(Y/N): Kanna? 

She was so focused on them. 

Ruby: She's been so into looking at those kids. 

(Y/N): If she wants to go to school, then I'll get her into it. 

Ruby: Then we need a resident card, education certificate, and textbook grant certificate. 

(Y/N): Hmm ... got a laptop? 

Ruby: Yep! 

You both got to work on getting Kanna's credentials so that she could attend school. 

And then... 

You started buying Kanna the supplies she would need. 

(Y/N): Kanna! Are you ready? 

Kanna: Almost, Papa. 

Kanna appeared with her big backpack. 

Kanna: Ready. 

(Y/N): My baby girl is going to school! 

Kanna: Wicked. 

And so... her first day began... 

Teacher: Hello class, today we have a new transfer student joining us. Kanna (L/N). 

Kanna: H-Hi. 

Student: Wow, she's cute! 

Student 2: Where did you transfer from? 

Kanna: V-Vacuo. 

Students: Cool! 

Tohru was outside watching everything. 

Tohru: I won't decline an offer from you, (Y/N)! 

You had told Tohru to make sure Kanna's first day goes smoothly. 

Kanna was already getting popular as she proved to be super good at solving math problems. 

Tohru: Hmm ... individual differences are bound to appear even when learning the same things in the same environment. Isn't this a rather inefficient method of education? I believe changing the classes according to their ability level will hasten their growth. 

And then during PE... 

Kanna was merciless at dodgeball! 

She was completely destroying her opposing team! 

Students: WOW! YOU'RE AMAZING KANNA! 

Tohru: They either alienate the one with power or accept them as a friend. How juvenile. 

PE Teacher: Hey, what do you think you're doing? 

Tohru: Uh ... I was never here! 

She left. 

PE Teacher: HEY! COME BACK HERE! 

Soon... 

???: HEY! KANNA (L/N)! WAIT JUST A MINUTE! Don't you think you're standing out too much?! A transfer student should be more modest! 

Student: Uh oh, it's Saikawa. 

Riko Saikawa (She is known for being a bossy girl, and is disliked by her classmates, but she's really an insecure girl!) 

Kanna: I'm standing out? 

Saikawa: YES! Those clothes are way too cute and you're almost good at everything! It makes me so angry I just want to hug you! I challenge you, Kanna (L/N)! I shall show you that I am the superior one in this class! 

Student: Just ignore her Kanna, Saikawa likes to play dirty, and she never accepts defeat. 

Saikawa: I HEARD THAT! How about we arm wrestle? I may not look like it, but I'm a black belt in Karate! And- 

She noticed Kanna crying. 

Kanna: Wh-Why? Why are you being so mean? I just ... I just wanna be friends. 

Saikawa: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH! I'M SORRY I'M SORRY! I DIDN'T MEAN TO MAKE YOU CRY! I JUST WANT TO BE YOUR FRIEND! Here, want some candy? 

Student 2: Saikawa, you know you can't bring candy into school right? 

Saikawa: SHUT UP! 

After school... 

Both Tohru and Kanna walked home. 

Tohru: That was pretty smart. Pretending to cry? 

Kanna: Yeah. 

Tohru: Why did you want to attend school? 

Kanna: It looked fun from what I saw. 

Tohru: Did you like it? 

Kanna: Yeah. 

Tohru: I believe there will be things that are not fun as well. 

Kanna: Yeah, that's true. We are dragons in human form, so there is no need to be equal to them. Being together is not the same as living together. But, because they;re close by and live in the same time ... that's what might be making me want to be together. 

She thought of when she accepted you into her home and into your massive circle of people. 

Tohru: Being together... I have sen many kin who chose to be buried together because just "being together" wasn't enough for them. Yes, for now we can be positive about that. 

At home... 

(Y/N): So tell me, Baby Girl, how did it go? 

Kanna: It was fun. 

(Y/N): Did you do good? 

Kanna: Yeah. 

(Y/N): Did you make any friends? 

Kanna: I made one, her name is Saikawa, she's nice. 

(Y/N): Aww! That's good! Here. 

You gave her a little trinket to put on her backpack. 

Kanna smiled and hugged you. 

Kanna: Thank you, Papa. I love you. 

(Y/N): (blushing) Me too Kanna. 

You pat her on the head. 

(Y/N): I love you too, my baby girl. 

Tohru: (Y/N)! WHAT ABOUT ME?! WHAT DO I GET FOR WATCHING OVER KANNA?! 

(Y/N): Ugh, I swear you are so needy. 

You kissed her on the cheek. 

(Y/N): How's that? 

Tohru: Aaaaaaah. 

She passed out with a big smile on her face and lewdly heart eyes.
