Yes, I think it's like dying, though from the sounds of it, you come back. It's just not a pleasant experience, very painful like starving yourself and wasting away.

[Well, that is cheery Shizusumi, geeze. He does not think it is a constant need for touching but more frequent touching than he is used to.]

If we're going to survive on me petting you and you hugging me, I think we'll struggle. We have to generate it daily or close to it. Chroma is how we pay for everything and stay alive. [Meaning they need it and not in small amounts. Shizusumi pulls his hand back and activates the device. He pulls up his chroma to show Hiiragi. As they stand there not touching after a while, it depletes, not by a great amount as it is a short period of time. Then he reaches out, ruffles Hiiragi's hair again, and it goes up, not as much as it lost, however, as it is a simple, friendly touch. He closes it.]

I think a hug would get more; from what I heard, the longer or more personal the touch, the more it generates and the longer it is before you have to get more. Some people do what they call moonlacing with a lot of people, some with just one.

[Which means they could scrape by most likely on their normal routines. But it would get slim, and they would both probably end up on the cusp of crystallization, finding themselves more sluggish than usual.]
