[@makarov] I'm not sure...maybe some sort of exception on school days? It isn't likely that he will be killed at the school so he wouldn't need the exception a lot but it could happen so he needs away back so not to miss a whole day of classes.

How about a ring that when he's wearing it in the real world and gets killed he instantly regenerates in the graveyard...it'll be incredibly painful...so he'll only use it to make sure he doesn't miss school?
