>>41837668Most of the story either focuses on her or something involving her, whether it be her family or the very legendary itself. She's an easily marketable cutebait character who takes the focus of the games away from actually being about the main protagonist, what with interrupting the main story countless times and telling you where to go for reasons that delay the game artificially and dumbs down the user experience. So, yeah, she's a Mary Sue alright, designed to be a waifu for virgins and a character for e-girls who thrive off of clout and attention to project themselves onto.
