not at all. for me a writer to just "ask" the readers to accept that as fact without any explanation because its the "genre" is just poor writing. to illustrate,

Spoiler for examples:

Strike Witches gave as the thesis that witches power goes down as you grow older. Nanoha was actually more of an accident becoming a Magic user at that age. the adults in their universe were even amazed she was powerful at that age, and there were a lot of adult magic users there of BOTH sex. mmm for others CC Sakura was the only one (in their world) and is a special case being the reincarnation of clow, sailor moon et al are also special since they are also reincarnations of their former magical selves. they're not really your random regular girl around the block. and so on...
oops are these spoilers?those are old series right.... mm just to be safe ill spoiler it.

point is QB is making contracts with minors, who most probably is not even matured enough to understand the consequences of their choices. and there aren't any explanations yet why he cant make a contract with someone older and yes if you prefer why not a boy/man
