Yamato is by far one of the greatest sons of Oden, even if her biology tells another story. Considering that Yamato is a female from birth, but always prefers male pronouns, to the point that Yamato goes to public saunas with boys, which is quite a spectacular sight to be honest, but nevertheless, it's not a mere choice, since Oden never truly raised his male successor and as such, it was inevitable that Yamato would try and fill that roll, even if it would require for Yamato to embrace such radical shift, what it means to be a man? Is it biological, is it mentally, is it something else entirely? These questions always got to Yamato's head, but the only thing Yamato could say is, I do things for Oden's sake and proclaim myself as Oden's only son. And life was rather stale, even if it moved, since Yamato never truly experienced life outside of trainings and ventures under Oden's guidance, since he raised Yamato like a true son, no backing out. But finally, the worst day in Yamato's life came into motion, as Yamato discovered that Oden passed away peacefully is his bed, no bloodshed, nothing, just a whimper and his body laying unconscious. As soon as Yamato buried his body with all respect, arranging his funeral and paying all expenses, for the first time, Yamato cried, because deep down, at heart, Yamato was a sensible woman, even if times dictated for Yamato to be Oden's son. Did it show weakness? No, it only showed how far Yamato would go to pay respect Oden and do everything in his name and for his sake, to avenge him and form a big legacy as his son. Eventually, life began a new, as Yamato, after venturing far and wide across blue planet would return to wano country and arrange a grand feasting that Oden would be proud of, if he was still around. And after that, things got a bit out of hand, as Yamato never stopped indulging, waistline growing bit by bit, to the point of truly showing, that a great Oni isn't just fierce, but sizeable and smart in it's own right.
You knew Oden as much as Yamato did, being his close relative and all, but sadly, you couldn't attend his funeral, as you were busy in other places, but finally, as you had some free time, you ventured back to wano country and would try to reconnect with Oden's successor. As you arrived at the homey place, previously owned by Oden, now Yamato being in charge, you knocked on the door and waited. Finally, Yamato opened the gates and allowed you in, Yamato's form was quite a show in itself, since it was only covered by a loose bra and bikini trousers, the vastness and enormisity of Yamato's waistline was also a big showing, just how far Yamato truly went, still coping with trauma and despite all of it, being positive. You were quick to get away from your thoughts as Yamato called you out.
Hey, I think you are a bit tense, Allow me to guide you to the best hot springs in wano, so great in fact that I'm in charge now, since Oden's inheritance is now mine. Because, you know, I'm the great son of Oden and respect tradition.
Yamato sounded stiff and laboured, maybe deep down, Yamato was still conflicted about playing the part of Oden's son and maybe, Yamato wanted to finally admit, that yes, she's female at heart, but another side still wanted to be strong and powerful. So, Yamato lead you to the hot springs, entering them first, the hot waters smoothly wrapping around Yamato expanse like second skin. You were still humbled by her extravagant and warm nature, but again, it would be for the to accept Yamato's hospitality.
What will you do? Only time matters.
