Substories are optional side missions that offer unique stories and often provide significant experience point rewards. They are typically marked on your mini-map with a question mark icon. Some substories require specific conditions to trigger, such as visiting a certain location at a particular time of day or having a certain amount of Charm experience. Always talk to people with speech bubbles above their heads, as they often initiate substories. Completing substories is an excellent way to gain experience for all five categories, making Kiryu stronger for the main story challenges. There are over 50 substories in Yakuza 6, each with its own charm and challenges.
