Noticing that the rubber on Koyori's paddle has worn off, affecting her play, Hokuto suggests that she buy some replacements, only to find she has no allowance. To this end, Koyori starts working part-time at Hokuto's family table tennis store alongside Hanabi in order to earn money for new rubbers. While trying to work up the courage to deal with customers, Koyori ends up serving a rather peculiar customer. As Koyori gets used to her job by the time Agari and the others come to check up on her, Hokuto recalls how she became friends with Hanabi.
