Well get to explore more about Leonidas's actually personality outside of his usual brashness that annoys people, especially his flashback about him and his brother seemly highlights his low-self esteem-something unfortunately being ignored MANY people outside Hiroto, including Moldias who is so detested his own kin so much that he'd better off to have Hiroto join the Privy Council while ignores his warning about Hydran whose reign would be far worse than even Leonidas.
