The missing crystal - S1.E18

Aiko was taught archery by Seiya Tsukahara. However, even if Spank has mischieved and broken the bow, Aiko doesn't have enough savings to buy a new one. Spank tries to work part-time and buy a bow. Staying at home, and selling ice cream, but it doesn't go well. When Fujinami and Osaki saw it, they knew the feelings of Spank and gave him money. Spank is overjoyed to buy a Western bow and deliver it to Seiya Tsukahara. Seiya allowed Aiko to practice again because of the hardships of Spank. Thanks to Spank!!
