[That phasing in and out worries Soma. He's seen it before - he's DONE it before, albeit in a very limited way. He draws some conclusions - some correct, some not - based on that and her appearance, and places a hand on Hanyuu's forehead. NOT the one with the ring on it.]

I'm going to give you some power, to try and stabilize your form. This is probably going to feel a bit weird, but it should be painless.

[So saying, he focuses inward, delving into the well of power provided by the ring. It's flickering, maddening, intoxicating and mind-bending, but he steels himself against it and takes from that well what he needs - what Hanyuu needs. Within himself he transmutes that power, drawing off the corrupting forces and tucking them away - his own soul is already dark enough, a bit more isn't going to hurt him - before transferring the clean, pure magical energy into her.]

[He staggers a bit when he removes his hand, looking bone tired but satisfied. He's done what he can, for now - the rest is up to Hanyuu.]

We should get her someplace safe and soft. I think Tau is just about drained, and I know I am.

[Aaaand that's about as far as he gets before he collapses. Face first, right into the grass.]
