Trying to prank Mikan.

While she may appear to be cute and innocent on the outside, the truth is that the Ultimate Traditional Dancer, Hiyoko, is a very mean and rude girl, who likes to bully other people around to do her bidding, and to put mean pranks on them whatever she wants.

And it just so happens that the favourite victim of hers, Ultimate Nurse Mikan Tsumiki, is currently having swimming class, meaning that her clothes are in the locker room, just waiting to be destroyed.

Deciding not to waste a good chance to play a mean prank on her, Hiyoko began to plan her nasty scheme. First, she will fake being sick to avoid going to the swimming class, then, once Mikan and the others had changed and entered the pool, she will go to the locker room to hide and/or destroy that Pig barf's clothes. Truly a master plan.

"Alright everyone, it's time for the swimming class, please go over to the lockers to change", said Chisa as the class ended.

"Heh, that dumb bitch won't know what's coming to her", said Hiyoko to herself as she began to put her plan in motion.
