SoniAni: Super Sonico The Animation - episode 9 - 02 Mar, 2014

Sonico and her classmates participate in a college fair, starting off by helping out at a sailor maid café. Her schedule soon becomes busier when she is asked to fill in for both the Light Music Club's guitarist and Ouka's modelling work, due to both of them falling ill. She soon learns she has been entered into a beauty contest, which coincides with her mini-concert, whilst the café suddenly requests her help at the same time. With Sonico torn between the three jobs, Suzu and Fuuri disguise themselves as Sonico to fill in for her at the café and contest, whilst Sonico herself performs in the concert. With all the commotion settled, Sonico holds her marine biology exhibit for all the children. (Source: Wikipedia)
