I don't care about ages of virtual characters, but... Aina is part of new arks and she's just 15, also looks at the outfit she's wearing.
No more revealing that that of Margareta's "royal wardrobe" from EP.5, who is suppose to be what 14?
There are a cluster of NPCs ranging from modest to very little to the imagination in outfits they wear while being from a varying degree of ages with their designs of short to tall.
Comparing Aina to any of the current or past characters of near to similar age range, what she is wearing is seemingly modest - including thematic, given how the introduction starts off and ends. Not including how the other NPCs are designed in that specific region of the game / introduction hold similar aspects, not the same but similarities. Versus say Manon, Ran, Liu Li, Rossa and Oranje who if it wasn't for the difference in name and hair could all roughly be the same NPC with a generic wardrobe that doesn't stand out against the others. As well, outside of Manon looking like generic ARKs member, Crawford's gal pals seeming appear shorter than or close to her height Aina while being more ARKs themed in clothing.
If there wasn’t issues with something, this topic wouldn’t exist cuz the restriction wouldn’t have happened.
I just question who did it: ESTsoft, Sega, or maybe even Microsoft...
I'll assume it is most likely Microsoft's direction to ESTsoft working with Online R&D in collaboration with Sega to have the idea of a more westernization feel / approach versus letting the product do the work as intended, self imposed restrictions probably got placed during the first talks after given the time frame then. Focus Groups - who probably (I assume) made snark and snide of what was shown of the Players versus the content, but as well showed interest in in the game - which drew to what we have now versus what is in JPN.
