That's jaune, JOAN OF ARC (in french Jeanne d'Arc ) was a religios peasant girl who initiated a religious crusade to reclaim french territory against the english men and succeded.

Speaking of jaune he may have a hero lineage, but tell me, do you know any famous hero who has a hero lineage? and no wiki pls, maybe some locals know and some family friends but at global scale?...nope, the heros had his time of glory, the desendants... not necessarily , jaune want to be a hero because of his lineage not because his family are a bunch of baddases, my head canon is that crosea mors was only a wall decoration, a family treasure because of the historical value and Jaune is the first hunter in training of his family in a long time.
