Sekine invites Chiyo to a sleepover at her house, and the other two invite themselves as well. They deepen their bond while Rikka learns more about the quirky cultural activities that take place on Earth.
The ultimate dedication 
to the "girl with glasses" trope!
Ein Brillenträger-Musterbeispiel!
¡Cuánta dedicación para los lentes!
¡Cuánta dedicación para las gafas!
Comme tout personnage à lunettes !
Che dedizione al cliché
della ragazza con gli occhiali!
É muita dedicação pra
ser a "garota de óculos"!
Поразительная приверженность образу!
