He sighs quietly, hand reaching up to push his bangs of his hair out of his face, he's not sure if he really can help Shion, doesn't know if his method of controlling his Darkness can be applied to anyone who's Darkness isn't manifesting in magic, but... he can't leave Shion like that either.

"...I can't make any promises that it will work, but if you want, I can try to show you how to control Darkness."
