I've got to say it finally, but "debutante" != "debut".
The debutante is the lady on the day of her debut. You can't say "she has her debutante", because she is the debutante. Rather, you'd say that she has or had her debut.
Johannes looks like he's seen some shit. I still wonder why he so specifically picked out shuli: a then-14 year old girl from a weak family. If he simply wanted a guardian he didnt need to pick up such a young girl.
In the beginning he says that "if its you, you can do it..." does he know about the time relapse?
