Arjuna is fully aware of everything in Mifune city

Spreading your mind outwards to comprehend the fullness of reality around you is far easier with your AC Organ, but it wasn't like you couldn't handle your full awareness before. You just didn't like using it all. It made everyone else look...flat. Like they were missing massive chunks of what should constitute an actual person compared to yourself. They weren't hyperdimensional like you, nor were they achronal or transplanar. They were just normal people, and to you they looked like barely functional caricatures of actual human beings when you had your senses open like this. But...for the sake of avoiding another Araya, you practice keeping yourself fully aware. (Now fully aware of everything occurring in Mifune City at all times!)
