"Rainy Season Sky: Quartz Rainbow"

Title : "Rainy Season Sky: Quartz Rainbow" "Tsuyu no Sora: Hari no Niji" (梅雨ノ空・玻璃ノ虹)
Summary :
Kanata goes with Noël to get more parts for their tank, the Takemikazuchi. They visit a glassworks shop run by Naomi, the lady who helped Kanata when she first arrived, and she takes interest in a glass dolphin. Later on, they run into Yumina and a couple of kids. The boy, Seiya, gets angry at them, since he hates soldiers due to the death of his parents. Kanata and Noël then go to a glassworks factory, where they are having trouble replicating the optical lens needed for the tank. Having noticed Noël feel down following the argument with Seiya, Kanata tells her it's not the machine that's good or bad, but the person inside it. After speaking with the workers, Carl and Maria, they give Kanata advice that allows her to become better at playing the bugle. This in turns helps Noël determine the effective lens samples by having Kanata check their sound. The tank works and Noël smiles for the first time in a while.
