Akira would be perfect for any kind of rogue/thief, and I'd love him as a arcane trickster if we're specifically talking about dnd. Warlock would suit him as well! With a fey patron. There are so many possibilities for Goro, I'd have to narrow it down, but I feel like it'd be possible to explore a lot. A warlock would be interesting. Something like Percy's gunslinger in cr could fit him, maybe leaning more into the pact. I've seen a few paladin concepts, which are also interesting. Maybe even a warlock masquerading as a paladin?
