Yukke's singing has a kind of "raw" feeling to it. His vocal techniques definitely are quite different from a dedicated singer, but the emotions are extremely strong. I got nonstop goosebumps starting from 3:09 until the end. Especially the part from 3:24 to 3:34, where he basically "talks" to the character in his mind and looks up at the ceiling, it pulls me into the scene immediately and deeply. That's the same kind of feeling that I sometimes get when watching the performance of very experienced singers. I can only say さすがはゆっけ氏ですね!
