Summary:
As Summer rolls in, Kodaka asks Yukimura to provide Maria with her lunches in his place, though Yukimura misinterprets what qualifies as 'healthy food'. As the group decides to exchange e-mail addresses so they know who's coming into the clubroom over the summer, it is revealed Sena doesn't have a cell phone. She ends up getting the same model as Kodaka's, only to get spammed by a jealous Yozora.
