Kana participated in meetings such as the "New Product Tasting Party" and began to get used to the workplace, but caused some trouble. Kana made a mistake in shipping and sent a defective water purifier with a stupid note to the customer. Unfortunately, the buyer posted the defective image on facebukko. The situation has come to the ears of the manufacturer of the purchaser. Kana is a big panic! Meanwhile, the trouble is settled by a secret weapon of the uncle's boss. Kana becomes a little more respectful of her uncle.
