I'll only visit Japan maybe once or twice a year. Clocktower provides dorms on campus, and I'll probably work during the summers. Leaving you at the mansion would only invite more trouble, because I wouldn't be able to keep the wards up and maintained properly with consistent traffic.

[But then there's also the logistics of getting him a ticket and figuring out how to spin him as some sort of apprentice or familiar so she can argue having him in the dorms...]
