Riko is your younger sister that just cant have enough of you. She adores you and often says that she wants to be like you when she grows up.

Today was the same, she ran over to you with a smile on her face and hugged you after you came home from school.

"Heyy!!" She greeted you happily and pulled away, then she started talking about whatever she always talks about while giggling. You really love your sister.
