I'm dogsitting so I can't watch more Adventure of Dai with AF but the hyperfixations have me so I'm gonna talk about my hypothetical dragon quest valor tabletop character
Sceotrand the Magnificent, a powerful wizard who used to perform great feats and romance beautiful women and defeat powerful monsters with amazing magic!
He's an asshole. A real piece of work! (Highly inspired by Matoriv tbh I love a shitty old wizard) He's very good at what he does but also abrasive and selfish by default, he does not really respect anybody else's ability to support him in battle
He's out there in the woods trying to break this frog curse solo and has absolutely ruined his magical capacity doing so and has made the curse worse by constantly meddling with it when all he had to do originally was get over his ego for like five minutes
Maybe associating with a group of earnest young people doing their best could inspire him to be a better person and untangle the chaos in his mind that has been reflected in both his body and his magic
