The personality AND body types both X and Yvonne are depicted with do not correspond with that of a 12 year old, you should be looking at Largo or Manon for the real appearance of a 12 year old (in childish clothes but a 12 y/o still). Kusaka can only slap an age on the characters after his editor's approve it, and given the audience of CoroCoro Comics, it is evident they cannot relate much with late teens/young adult characters. And even if you were to pretend that such decisions aren't a thing, the way were written also doesn't correlate with the personality of a 12 year old. It just doesn't make sense for somebody that age to react to life or take life-or-death decisions the way they were doing it because guess what? Adultlike, mature behaviour is seen as something cool and heroic by kids.
