Pudding, the initial group got shoved in the mirror world by forces unknown themselves, and our new buddies claim other people have been too, so we know full well something's going on with it. I believe the plan was that this thing right now would be a bit of a demonstration on how mirror world stuff is supposed to work, THEN Noboru would be kidnapped, and THEN it would be dungeon time. But anyway... Sho. I know it's less than ideal that Savo decided to have Kami bugger off to make puppy eyes at Ayano, but come on man, this can be worked around. If you were paying attention, you would know he set it up like Kami was going to be late and that happened at the end of his collab with Haru. There's no need to treat this like the end of the road, so let's just pretend Kami is an idiot, that he showed up late and THEN we can all move on with our little happy happy joy joy fun time training nonsense. Blech.
