His head jerked up, and he saw no one inside the hall when he suddenly heard a clapping sound inside the hall.
Clap! Clap! Clap!
Now he could hear that the source of the clap was very near to his right ear, but when he turned his head, he saw no one. "Who are you? Show yourself?" he shouted in full vigilance.
"You've grown up to be a great seedling, a great sensei." A mechanical voice echoed inside the hall and a silhouette cloaking in all black appeared in front of Kemino.
Kemino took out a fountain pen from inside his shirt and the next moment, the pen enlarged and abruptly transformed into a black Katana with a rubber handle. "Who are you? And how are you sneaking in here?"
"Ho-ho-ho, you have the Katana of Enlightenment, too. Good, good." the man in the cloak praised him with a light chuckle.
"You know about my katana?!"
