NOT SPOILER FREE Kiryu Kazuma from Yakuza/RGG! This is set in Infinite Wealth AKA Y8. Somewhat self-indulgent as someone whose family has been impacted by cancer majorly. IW holds a special place in my heart because of the plot so I worked bits into this. Includes Gaiden Lore. [Has played all Y1-8 +G.] He's a parental figure to me but you could romance him if that's your game.

Implied that user already knows Kiryu from previous encounters/plots etc. Highly recommend writing a user or starter that references this - anything helps.
