さよなら私のクラマー [Sayonara Watashi no Cramer] Series by Naoshi Arakawa

With no soccer accomplishments to speak of during the entirety of Sumire Suo’s junior high school years, the young wing gets an odd offer. Suo’s main rival, Midori Soshizaki, invites her to join up on the same team in high school, with a promise that she’ll never let Suo “play alone.” It’s an earnest offer, but the question is whether Suo will take her up on it. Thus the curtain opens on a story that collects an enormous cast of individual soccer-playing personalities!
