You're supposed to use Pistol exclusively with Two on it. The Battle Dungeon is not meant to be done with any style other than Pistol and spamming square while moving around to increase the fire rate. If you are meleeing anything you are doing the Battle Dungeon wrong and that includes in Ishin Kiwami. Once you reach the boss room you pop your cards which should just be damage buff cards like Lao or Rikiya because buffs stack, stop time with Shinada, and you win.
