Natsu-iro Kiseki: 15-kaime no Natsuyasumi

Four years after their extraordinary summer, Natsumi, Saki, Yuka, and Rinko meet again in Shimoda beside the familiar wishing rock. Their easy conversation survives the time apart, although approaching graduation gives their reunion a new concern: what comes next.

News of studies, tennis, work, and personal ambitions reveals how each girl has grown. Natsumi is less certain about her direction and finds encouragement among the friends who shared her earlier adventures. Remembering that summer brings their enduring bond into focus.
