Yumi
"Good!" Yumi said, dodging as Keiko slashed at her. It was a meager swing, one without too much effort, but that was exactly how Keiko had to move. Any further exertion would result in her throwing up.
"Ah," Keiko said, breathing heavily. "Uh, give me a moment," she said, walking over to the nearest bench and sitting down.
"Still feel alright?" Yumi asked as she sat next to her, putting a hand on her shoulder.
"Yes," Keiko nodded. "I'm just tired."
That was understandable, as they'd been at this for several hours. Not to say that they'd spent every single second of those hours fighting, but rather, Keiko would swing her sword a little, the two would take a long break once she tired herself out. Then, later, once she'd feel ready, they'd go at it again.
