A maze of fire - Sayaka's initial reaction was to just jump through it instead of wasting time navigating, but after ducking through one wall of flame and having her body erupt into a mess of noisy chimes as the resultant burns were healed away... she realized that was a bad idea.

There is something to be said about bull-headedness leading to mistakes, there.

She could still rely on magically enhanced speed, however - Sayaka dodged and weaved through the fire with sharp, unpracticed movements.
