>>49866691If it's fan art by a Japanese artist, no. Art like what you posted strikes me more as the aesthetic sensibilities of an artist having some fun, vs depicting the characters as weeaboo. Or when characters are shown in Japanese festivals, the artist is just depicting celebration in what is familiar and comfortable to them.
But Grimsley, wearing a kimono in canon in an established setting with established cultural aesthetics, is cringe-ass weeb behavior.
