Kirino Aki

The protagonist's cousin and cousin and childhood friend of Asaka. She's an energetic, outgoing, and cheerful girl. She affectionately calls the protagonist “big brother.”

She used to be tomboyish as a child, but has since grown into a cute young woman with a distinctly feminine physique. Being at that age where she's infatuated with romance, she's developed feelings for the protagonist, who she's always been close with.

She's extremely easily embarrassed; even the slightest teasing makes her ears and face turn bright red.

At school, she belongs to the track and field club, which has only two members—she being the sole athlete. Her specialty is sprinting. She even practices on her own at school during summer break, giving her a healthy tan.

She's a dependable person who often looks after the village children in place of the protagonist, who left their hometown. She has never left this village.
