Natsumi, finished with the school day, had taken the time to go to the locker room and change out of uniform and into something more comfortable--though it was anyone's guess if a crimson furisode could [i]really[/i] be considered sensible casual wear--before repeating a daily ritual: it was time to hunt down Akiko and lead her home. The white-haired girl had learned that the younger girl would stubbornly try and find her way home, then get lost almost immediately. 

So she'd stopped going home before changing, and just gotten used to changing clothing first. That way, if the other girl was [i]too[/i] lost, she didn't spend hours upon hours more in attire she would rather not wear.

Fortunately, today she found her friend almost immediately, though most people would have missed her.
