Two.
[The scene is clearly a dark part of the city, and Mifune is currently walking slowly towards where he had been last night, gaining bounties through members of the mafia. He had been a bodyguard for one before, so he knew how they worked surprisingly well. He had to cut apart rival families, after all. Either way, he had victoriously gained quite enough money to last him awhile with Ashura (though the kid did sure seem to eat a lot), but when he had looked over his artillery of swords, one had been missing. Not wanting it to be in the wrong hands, he was forced to go back and retrieve it. While it may seem ridiculous to go back to the scene of the crime so soon, there was still the chance it was stuck somewhere no one would notice it. Even if it was gone from the area, he was going to get it back. He was rather attached to the large amount of katanas he wielded at once. Which, of course, he had on himself now. Though to anyone watching, it would only look like he had one on hand.]
