|Episode 11 - You See, Girls Wearing Yukata Are Extremely Cute|
Wikipedia summary: <spoiler /><spoiler>
Although Yozora brings up the upcoming summer festival, she but declines to attend due to crowds. Rika also demurs due to her past experience with a summer festival. When Sena mentions takoyaki, the entire club decides to go for the purpose of getting takoyaki, which Kodaka is passionate about. As they walk to the festival, Kodaka and Kobato change into yukatas at Sena's request. Yozora declines to change into a yutaka, disappointing Kodaka. After changing, Sena finds Kobato attractive, but also decides that Kodaka's hair ruins his appearance and wants him to dye it. Kodaka replies that he cannot dye his hair color since it is a legacy of his deceased mother, impressing Sena. After having their fill of food, Yozora and Sena compete with each other at the games stalls while the other members enjoy the other stalls on their own. Later, everyone gets together to set off fireworks. After the last one is set off, Yozora's hair catches on fire, forcing Kodaka to throw a bucket of water on her to put it out. Soaked and humiliated, Yozora leaves and stays away from the club for the last week of summer vacation. On the first day of school back from vacation, Yozora arrives in class with her hair cut short. The change in appearance leads Kodaka to finally recognize her as his childhood friend, nicknamed Sora. </spoiler>
My comments: <spoiler /><spoiler>
It's very obvious by the beginning of this episode that the childhood friend is Yozora. Kodaka probably didn't know her very well and didn't realize that she was a girl acting like a boy... and yeah the end confirms it. Yozora decides to cut her hair, and Kodaka finally go back to calling each other by their nicknames, Sora and Taka.
I liked that little bit of lore about why Kodaka doesn't dye hair black to avoid being seen as a delinquent... It's because that hair color, and Kobato's appearance, are the only things he has left that remind him of his mother.
Most of this episode was just boring cliche festival stuff.
