Part of Kaworu wants to shy away from the call, like a lost kitten who didn't know warmth and safety from the cold and the wet and so shied from all contact, fearful it could be worse than what they've already felt.

But he can't resist the softness in Midoriya's voice, he never really could, not even the first time they spoke in a warm hot spring. Izuku's presence is warmer than that hot spring could ever hope to be.

"I'm here."

Kaworu's soft voice calls out. It's no siren call, or a cry for help, just an uncertain acknowledgement that he exists in this space. "I'm here, Izuku...-kun."

Does he have the right to call him by his given name?
