K-ON!! Season 2 episode #2
The Light Music Club members decide to do a spring clean, finding an old guitar of Sawako Yamanaka in the process. While selling it, it turns out to be more valuable than expected.
The episode starts with Tsumugi Kotobuki starting cleaning the blackboard after the english lesson. Ritsu Tainaka and Mio Akiyama are surprised about Mugi being responsible for the day's duties, to which Mugi replies that the actual person in charge is Yui Hirasawa, who is peacefully sleeping on her desk. With the aid of Nodoka Manabe, they try to wake her up, but even luring her with fake sweets isn't working. At the moment Ritsu orders Mugi to get a real cake, their teacher Sawako Yamanaka shows up with the request to turn back the animal costumes they were using to attract freshmen for their club earlier.
Arrived at the clubroom, they search for the costumes in the terribly cramped storeroom, a sight which greatly shocked Sawako. After Ritsu got buried under a junk-landslide, Mio decides that the storeroom needs a spring clean.
At first, Yui and Ritsu struggle with the idea, but since the cleaning personal is not able to do it for them because the whole personal stuff hinders them, they decide to do seriously. After finishing cleaning the room, Yui finds an expensive looking case which was overlooked at first. Inside lies an old guitar, which turns out to belong to Sawako.
Azusa finds out that Sawako was once a member of the Light Music Club too and starts to ask for personal lessons until Yui shows her a picture of Sawako being a member of the band Death Devil, leading Azusa to withdraw her request. Sawako, unwilling to take the guitar back home, offers the club to sell it for her and use the money for the club's deposit.
On their way to the music store, Yui has to tow the guitar alongside her school stuff and personal belongings since she keeps on loosing in "Jan-ken-pon". Mio brings up the idea to buy a shelf for the storeroom to prevent it from getting confusing again, so the club stops by a hardware store.
Inside, Mugi expresses her enthusiasm about being the first time inside a hardware store and starts adoring every common article she can find. Ritsu and Yui however use every item they can find to annoy the others, especially Mio and Azusa. After some time passes, Mio calls Sawako to ask her about the shelf, which is accepted.
Meanwhile, Azusa visits the animal section and is currently watching a Pig-nosed turtle when Yui shows up, just to instantly fall in love with the turtle.
After their visit at the hardware store, the group visits the music store which is run by Tsumugi's family. While the employee is estimating the guitar's worth, Azusa is secretly expressing her wish to know how the sound of their band would sound like if they would have more members. Before Mio could respond, the employee finishes his estimate and is willing to buy the guitar for 500000 Yen which greatly shocked the group. Ritsu asks the employee about the high price, to which he responds that the guitar is in a marvelous condition for its age and was also made out of very rare material, making it an highly valuable guitar.
Afterwards, the group visits a local fast-food restaurant to disuss what to do with that much money. Despite trying to resist at first, one by one (exept Mugi) is eventually corrupted by the opportunities the money could offer them.
The next day after school, the shelf is delivered and fits in perfectly. Just as Ritsu and Yui are scolded again for still having personal stuff inside of the room, Sawako appears to check out the new shelf. Wondering why everybody appears panic-fueled after she showed up, she asks about the price of her guitar. Every attempt to change the subject fails, so Ritsu lies to her that they've sold it for only 10000 yen. At first, the lie seems to pass, but eventually, Sawako asks for the receipt since she needs to file it for the club's budget.
Out of options, Ritsu tries to chew it down right in front of Sawako while the four others cheer her on. Sawako however stops her with a single glare. Happy about the actual price, Sawako decides to keep it herself since the girls lied to her. After granting Yui's only wish (to be slapped in the face with it), she backs down and promises to buy one single item for the club.
On their way home, the band discusses which item would be the best choice for eveybody. While seeing the new members of other sport clubs starting to get serious, Ritsu notices some grief in Azusa's look and tells Mio, Yui and Mugi the day after at school. While everybody wonders how they could satisfy Azusa's wish to have some freshmen under her, Yui gets an idea.
The next day, Azusa stands in front of her new freshman, the Pig-nosed turtle Ton, which she observed soem time ago at the hardware store. As Azusa did not react much, Yui justifies her idea by telling that she thought that Azusa might have liked the turtle since she stared at it intensely, to which Azusa responds that she simply thought of it looking weird. Nevertheless, she contented agrees to take care of it and directly tries to deter Yui from helping her, who was about to state she will take care of it too.
