(Yep, this chapter goes forward in time again.) Hiro decides to scoot after Da5id's crash. However, one of the Nipponese men stops him and asks about his swords.
It's pretty obvious that the guy thinks Hiro isn't worthy of carrying the swords and is itching for a fight, so, you know, they fight (we like to imagine this as though they're tiny plaid ninjas).
Hiro is not only a great swordsman, but he also wrote the software for sword duels in the Metaverse, so he cuts off the businessman's legs and beheads his avatar.
This essentially boots the businessman from the Metaverse; what he sees on the screen is a list of the top ten swordsmen of all time. Hiro's name is number one on the list.
