I'm playing Yakuza: Like A Dragon lately so I've been hearing the battle theme a lot these days.
I had no idea the track was titled "Yokohama Crackhouse" but it seems fitting for all of the oddball Sujimon on the streets of Ijincho.
I like the heavy synths they use for the battle system in this game. It's modern, but also reminiscent of the square waves that Ichiban probably remembers from playing Dragon Quest.
