Sword is socially awkward and immature, but heartfelt. Being the swordsman son of a deity, he takes pride in learning new and old techniques and utilizing them in combat, especially in phights. This leads him to shout out some of his moves cheesily. Despite this, his gear being a simple unmodified sword leads many to underestimate him on first impression, much to his ire.

Sword's voice should radiate his confidence in his moves. It should be clear that despite him being socially inept and frequently underestimated, he still thinks highly of himself and everything he's learned from his mentor. Sword should have a "Main Character" kind of voice, similar to English dubs of anime (albeit not nearly as exaggerated). A good point of reference would be Zeno Robinson's performance of Hunter from The Owl House.
