Hiroki pours himself into it, too.

Ziggy might now noticed that, even though it's not visible (but can be felt), Hiroki's spirit had been badly damaged. Can spirits be scarred? This one is, and when Hiroki shares himself with Ziggy, Ziggy can, surely, feel that. Like one would feel hundreds of distinct, jagged scars. Each one from the battle he had once waged against Honerva's possession.

I love you more, Princess Ziggy. Ziggy! I love you. I adore you. I'll always cherish you. You're perfect. And worry naught, love. I'll have a body again. I can feel.
