Aiko was always energetic and happy every time she would do something sportsy, but she wasn't always like this. Back in 2nd grade, Aiko thought sports were really easy due to her always watching sports channels, but whenever she tried to play basketball for the first time, she realized that sports were harder than expected. she would keep on getting hurt when she would practice and one day, she decided to give up. after Aiko decided to give up, Aru came up to her and said she shouldn't give up so easily and she also said that she was always watching and was really amazed by her determination at the start. Aiko then decided to always keep on going.
