[Riku can't hold the barrier any longer, letting it flicker out of existence as he draws in a deep breath; rather than to focus on the walls, he focuses on the lasers and his instincts, and draws the magic in short bursts rather than to concentrate on continuously maintaining it - he knows which of those is more draining on him.
It takes a good bit of judgment and luck to invoke the spell always exactly the moment before he is in danger of being sliced by the laser, but Dark Shield is Riku's second most practiced spell, one he's practiced over and over again under Mickey's careful supervision in those weeks before they had separated (it feels like a lifetime has passed since that time), and the spell itself hasn't changed, only the form he's drawing it into.
At least that means there isn't any danger of it exploding into his face.
There is enough hazard going around without him adding to it on accident.
Still, he hopes this will end soon. The room can't keep up spinning the whole time, can it?]
