Shuten-douji doesn’t talk about her wish for the Holy Grail. Just like how she was when she was alive, going wherever her fancy takes her, she thinks and behaves as she pleases, not being any different in the present days nor in the bygone days. Also, she is a collector of antiques and rarities, even having a keen interest in the Red Dragon Ulna dwelling on Kintoki’s arm. She appears to attach an importance on rarity and on the elegance of their appearances regarding those items, so she is incompatible with the King of Heroes who attaches an importance on the items’ history and performance.
