Ah, if only. Too bad your MC is kind of an idiot.
Then again bringing her along might just means putting a target on her for Mita. But at least you could try bring her out of that hallway.

Helping her or, heck, playing with her a little would have been nice.
But considering our situation leaving her there, away from us, is probably the kindest thing we could have done for her :(

I watched a playthrough with photo mode active and she appears in chibi Mita's level for a second then disappear.

I would've liked to play with her a bit, but something tells me the enormous spider-demon-thing would've gotten in the way of that.
