I found another anime doppelganger for Celestina other than Yu Mei Ren from FGO: Sakuya Kaguya from an anime called Shining Blade. I know nothing about it, but now I can collect more waifu merchandise.
@Tfmonkey Sumireko Sanshokuin from Anime Oresuki is a Doppelgänger for Celestina
@Scubbie her eyes are the wrong color. Celestina's eyes are a light copper brown.
@Tfmonkey just use the techniques modern women do to change the eye color filters,dyes contacts figures you could paint
@Tfmonkey womp womp
@Tfmonkey This is Aria Wintermint, she appears in a webcomic and has the look of an asian waifu
@Lorgar She looks like a loli based on her head-to-body ratio, but that may just be the art-style. Gives me Tim Burton vibes.
@Tfmonkey she's not a loli (big boobs). And yes the world she's in is fairly dark.
She is a good asian waifu.
Update: the anime is called "Shining Hearts" and the character looks different in the show, dressed like a pirate. The version I thought looked like Celestina was a "professor variant" which was made as a figurine but has nothing to do with the show or game. Disappointing.
