"Do let me know if you feel sick, at any point," Yumi told her.
"Yes, yes," Keiko nodded. "I will."
"Then, let's start."
Without Ash around, the day played out in the Manor in a fairly boring way. However, when Keiko decided that if she sat around any longer she was going to go crazy, she approached Yumi and the two decided to resume that makeshift training that the other Zayama had been providing her with. It made for what Keiko could consider the most fun she could have nowadays, when Ash wasn't nearby, anyway.
"Good, good," Yumi told her as Keiko swung her sword. "I'm surprised your attacks are still so precise, Keiko, good job."
At that, Keiko chuckled, a little embarrassed.
"Thank you."
The two of them went at it for a while, as Satsuhiro began muttering something to himself nearby.
