I did wonder if it was caused by the Vessel of Sin. That night, I used the Spring Onion to contact Elluka.
"Exhausted all the time, eh? But it's not as though he's stopped working?"
"I think maybe Mr. Keel is just sick, but there's also been something odd happening with his children and Mrs. Mikina. They keep feeling like someone's patting them."
Elluka seemed to be doing some writing on the other side. "…Ehh, doesn't really sound like the work of a Vessel of Sin. But keep a close eye on them anyway—and Keel, too. Tell me if you find out anything else."
