After the initial introduction between Kichiro and the man called Hanzo, Kichiro tried to pry in more deeper into his identity. He was forcing Hanzo to tell him about his real name instead.
Hanzo only looked at Kichiro and replied, "Maybe one day, but not for now. I believe calling each other names like this is way more beneficial for us rather than for you to know my real name. Don't worry though, I'll call you Ioki to be fair!"
Seeing the logic behind his reasoning, Kichiro decided not to pursue the matter further. Hanzo asks Kichiro to follow him closely because of how big this building they're currently in; Hanzo is afraid that Kichiro will lose his way and end up in a place where he doesn't want him to be.
"By the way, isn't this still too early in the morning? What about your school?" Hanzo asked while looking at Kichiro.
Kichiro replied, "Ah, don't worry about it! I already have my parent's permission."
