"THE WHISTLE"
"What have you got there, Masataka-kun?" Sonken asked.
"It's a whistle Minmei gave me. She told me to blow on it if I ever need her," Masataka answered.
"Does it work?" Sonken asked.
Masataka blew the whistle and Shuutai appeared out of nowhere.
"You called, Zangetsu-sama?"
"Shuutai, you were following us again, weren't you?" Masataka asked.
"Well, it's my job, Zangetsu-sama."
Masataka patted her head.
"Good girl."
Shuutai purred happily at the praise.
