Well, my point was if they played as Mirai & made that claim about HER specifically, I could see where they're coming from, considering her small physique. Still a rather young age to guess, but she easily looks the youngest, so whatever. Guess "valid point" was the wrong choice of wording.except it's actually nowhere near a "valid point"
Now saying EVERYONE is the same age (mainly freakin' 12), especially considering we've got characters over 20 years old (i.e Daidouji & Rin, but I'm sure they weren't in the E3 demo) is flat-out wrong.
