Pyrrha

After about a half hour of exploring the courtyards of Beacon, Ruby realized orientation for freshman was soon, so she started running to find where the assembly hall was. Briefly tapping into her Semblance, she ran far faster than the average person, but she was so focused on getting to orientation on time, she accidentally bumped into someone. Ruby fell to the ground as a result of the impact, her fall thankfully being cushioned by her diaper.

"I'm sorry!" Before Ruby had a chance to apologize, the person she bumped into said what she wanted to say. She had red hair and was dressed in Spartan-like armor. Ruby couldn't believe she ran into THE Pyrrha Nikos. Surprisingly, she looked very apologetic, and didn't even seem to be that bothered by essentially being rammed into at high speed. Then again, this was the Invincible Girl Ruby was sitting in front of. "Are you okay?" Pyrrha asked as she offered a hand to help Ruby up. "Do you need help picking all of this up?"

Ruby was going to ask what Pyrrha meant until she looked around and realized that the contents of her diaper bag had been scattered to the ground. Her wipes, powder, and rose-printed diapers were fully on display. "Uh... I can explain."
