One of the ways Like a Dragon: Infinite Wealth builds upon its predecessor is by expanding the party with more playable characters. While Like a Dragon: Infinite Wealth newcomers like Tomizawa and Chitose were welcome additions, what's more exciting was getting to play as Seonhee for the first time after she appeared as an NPC in Yakuza: Like a Dragon. If Like a Dragon 9 follows a similar formula, it's likely to include an NPC from Like a Dragon: Infinite Wealth as a playable party member, and there is already an obvious candidate for this role.
