There are plenty of cool magic weapons allowed by the rules. It's the DM's job to deal them out.One thing I noticed about a lot of these that I could think of offhand: they have a cool magic weapon. That’s something the official rules seem resistant to granting. Even Pact if the Blade grants a technically nonmagical weapon, you just receive it via magic.
Or play an artificer. You could make a good approximation of an anime character with a battlemaster artificer. I've seen enough anime to know cute pets are a thing.
