No "Senpai" Allowed!

No Upperclassmen Allowed! (先輩禁止) is the tenth episode of the ''Love Live! School idol project'' anime series. It was aired on March 10, 2013.

Summary
As the weather is hot, 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 creates a rule that no one is allowed to call their upperclassmen with the honorifics 'senpai' for the duration of the trip. From this rule, almost everyone is able to do this, except Hanayo, who still sometimes spontaneously calls her upperclassmen with the honorifics 'senpai'.

The girls spend the day playing around on the beach, although Eli and Nozomi are quick to notice that Maki doesn't seem to be participating. After dinner and a bath, Nozomi helps Maki become more sociable by initiating a pillow fight, blaming it on Maki. However, when a pillow accidentally hits a sleeping Umi, she begins to throw "supersonic pillows" at the girls out of crankiness, frightening Hanayo. Maki, however, ends up participating, and she knocked Umi out with a pillow. Umi falls back asleep due to this.

At the end of this trip, μ's somehow manages to completely break down the barriers between upper and underclassmen in the club. The episode ends with all the members of μ's holding hands and watching the sunrise.
