As the headquarters of the Mingyue Society, although it was originally a commercial building, after the Mingyue Society took over, it was remodeled, so there is still a very professional kendo dojo. It usually serves as the place for Kojo Kyoko to practice kendo, and now, it can be used as the venue for the duel.
"Girl, don't say I didn't warn you, I am a Kenjutsu Seventh Dan, not just any Seventh Dan, but a Transcendent's Kenjutsu Seventh Dan. Although Okuyama-kun over there had been instructing in the United States, his current level of kendo is only fifth dan. If you think I am on the same level as him, then you'd better be careful."
Before the duel began, perhaps influenced by Imahon Okayama pleading on her behalf, he decided to give Kojo Kyoko a chance to admit her mistake, intentionally displaying his strength.
