The old man is his father. The father is the Hero. The Hero gave him the clothes before left him
That's how he knows the Hero has a bunch of old relics etc that's also why he brags about it, having received something from the Hero while the elf didnt. Youre not delusional but rereading slowly might help bc that's multiple Plot points tied to it. His "old man" is the hero
Kuero, the beastboy, it's presented as the beastman's child and talked about his old man. Ok surely beastman includes females in that race and his old man is his grandpa, but I'm having fun thinking the hero impregnated an omega beastman. I'm gonna miss the furry.
