Mamiko @Junior high school student

https://www.aipictors.com/works/260928/ \'s older sister. When her senior reached third grade, Mamiko entered middle school and was no longer considered a schoolchild. Then, Rikka enters elementary school instead. Are you a little more mature than when you were in 6th grade? If you undo the braids, you might not be able to tell me apart from Natsuko lol. 3rd photo: Mamiko: “Ko-kun, Ricca-chan. Let’s get along well.” (They were loyal. On a level you never expected.)
