* Shouldn't Choco be going to school?
** Why would she? She already has a book that contains all the knowledge she needs.
* Why is nobody amazed about Choco's sudden appearance?
** They are. Its just that nobody around knows much about Haruma, so they probably never asked if he has siblings. When one of his relatives come to visit, that was a big problem though.
* How does Haruma go about the problem that Choco has no birth certificate? Getting dental care or health insurance would be a problem, for one.
* Of course, "Santa" could have seen to it that Choco has a birth certificate, identifying her as Haruma's sister, but why is that never mentioned then?
** Do we need to know all the details? He just got a little sister, packed with everything he needed of her. Being healthy and insured was also part of his wish.
