Titre original : Crisis!
When Ritsu is reminded by Nodoka to fill in her gym-use application, the band notice they don't have a name yet. Azusa notices rust on Yui's guitar strings, and it becomes apparent that Yui has never given her guitar maintenance before. They take it to the guitar shop where Mio gets entranced by a Lefty fair. However, Yui doesn't realise she has to pay for maintenance, and when Tsumugi tries to pay, the staff refuse to take money from her. They tell her to consider it as a free service. Later, Ritsu starts to become jealous of Mio spending time with Nodoka and begins to fall out with her. She ends up with a fever, so Mio visits and smoothes things over. Afterwards, Ritsu gets in trouble for still forgetting her form, but Nodoka backs her up. Since none of the members could decide on a name for the band, Sawako chooses the name "After School Tea Time" to get it over with. However, Yui ends up catching Ritsu's cold.
