Kids develop at different rates. Some are early bloomers, some late. But they're all still kids. We know the protagonist of SM, Hau and Lillie are 11. Lillie is depicted as being friends with Lana and Mallow suggesting they're fairly close in age. Ergo, Lana and Mallow are still kids, like Lillie and Hau.
This isn't rocket science and I don't know why people get so desperate to age up any character whose age is even slightly ambiguous.
>>53242081Like this retard. There's nothing to suggest she's much older than the main group and yet he buries his head up his ass like Bulbapedia personally gave him permission with that 11-19 bullshit. Use common fucking sense. And you don't have to be literate to make for a good example.
