Love Live! School Idol Project - episode 10 - 09 Mar, 2013

Honoka suggests that the group go on a training camp to the beach, with Maki coerced into letting them use her family's vacation home. Wanting to break down the barriers between underclassmen and upperclassmen, Eli puts in a rule that no one is allowed to call their upperclassmen 'senpai' for the duration of the trip. The girls spend the day playing around on the beach, though Eli and Nozomi are quick to notice Maki doesn't seem to be participating. After dinner and a bath, Nozomi helps Maki become more sociable by initiating a pillow fight. (Source: Wikipedia)
