Blue Period manga volume 4 features story and art by Tsubasa Yamaguchi.

Yatora now has new materials in his tool box and a wider range of expression under his belt. But a week before the first exam, Ooba-sensei says he’s missing a crucial edge… With so much at stake, Yatora’s self-doubt brings him lower than ever before. Still, he has his fire, his resilience—and he might just get a lucky break, too.
