[POLL] What should Nerd & Ash cosplay as? (Patreon)

I have the others costumes already hahah but Nerd and Ash are up in the air. I do have a slight idea of what they can wear but I want to hear your opinions as well since their costumes doesn't really have much to do with plot XD But the others does XD

Let me know in comment what you think is nice to see them in?
