In this chapter, the young swordsman tells his grandfather that he is training him to be a better swordsman than he is, so that he will be able to protect him from criminals. He also tells him that he has permission from his grandfather to use the school's dojo as a place to train non-members, so long as it is done in a proper manner. He tells his grandson that his grandfather had said that he had used his contacts in order to get permission to do so, but he is sorry that his request was not granted. He thanks his grandson for his hard work, and tells him not to worry about his time, as he knows that it is hard for him to find the time to train his students. He adds that he does not go easy on his students, and he will make his grandson proud of his efforts. He asks if he did the surprise attack on the commander, and zeroichi says that he thinks he may have done so under the butt of his butt. He then asks why his mood is so bad. He says that the gym is full of pent-up sexual urges, and that he wants to use hibiki as a stimulant to help him get rid of them.
