Stiff
You feel like a stone that’s been renewed. How do renewed stones feel? Stiff. Very stiff.
Think of a stone being renewed like it is having something like a spa day. Pedicure, manicure, the whole shebang. It’ll come out all stiff and hardened, cause that’s how good stones are.

You remember how you used to cure these stiff body times: your old friend こういち would just massage them out for you.
If only you could ask こういち to give you massages again, but he's too busy for you, now (being emperor and all).
