Kotone

Haruto’s average-breasted younger sister who lives in his home town. Because the Average Chests are of low social standing among both the Big Breast and Flat Chest tribes, the Average Chests have gathered in that isolated village to escape them. She’s extremely polite, so much so that it’s hard to believe she’s Haruto’s sister. She’s terrifyingly strong and is better with a sword than Haruto, but she loves her brother dearly and works hard every day to catch up to him. She saves the enslaved Average Chests, but both countries have put bounties on her head and nicknamed her the ”Scarlet Crow.” She has a complex about her average-sized chest.
