Homogenizing of characters, especially from media from Japan, ESPECIALLY media that is meant to /take place in/ Japan, have characters that are homogenized because, well, that’s how Japan is
Unfortunately, what you have basically said here is “all Japanese people look the same”. Which is… bordering into comically offensive. Homogenous doesn’t just refer to race, it can mean things like body type, or facial features as well. If a cast is comprised entirely of pale, slender, pretty, feminine characters, it is a homogenous cast. All of the men in Japan are not pale, slender, pretty, and feminine. Some are! But not all of them.
A WINDOW INTO THE THOUGHT PROCESS BEHIND MY HATOFUL GIJINKA;
Anghel: Is not Japanese. Luzon bleeding heart doves are from the Philippines, and the character himself is frequently referred to as Filipino by the other characters in the game. The other characters mention he’s in the anime club and he goes through life pretending he’s an RPG hero, as well Luzon doves are rounder and stubbier than the average rock dove or fantail. So I choose to draw human Anghel as a chubby little Filipino fanboy LARPer.
Sakuya and Yuuya: I put a lot of thought into these two because they’re supposed to be at least part French, but they have Japanese names so I wasn’t sure which direction to take it. What we know in game is that Sakuya calls Yuuya a mongrel and a half-breed, so for the sake of interpreting them as humans I took that to mean Yuuya looks mixed-race European and Japanese. If the story goes that the two have the same mother and different fathers, Sakuya being of French Pedigree would mean that their mother was the French (or at least European) of Yuuya’s parents. Since (**Spoilers for the full version here**) there’s the big revelation that Sakuya is actually Yuuya’s full brother, I figured that would mean Sakuya would look vaguely Asian, but still European enough for his “father” to accept him as the true le Bel heir. It is not uncommon for multiracial families to produce children who appear to be completely different races, so I’ll just go with that to explain why Sakuya seems to be European and Yuuya looks mixed. As far as their appearance goes, Yuuya is often portrayed as flirty and roguish. The pigeon photo they used for him is in the middle of doing a mating dance, so I figure that translates to easygoing, flirty, hip-jutted masculine body language. The way he calls you “little lady” and then interjects random French words into sentences makes me think of a teenage John Wayne throwing bad French around to sound more worldly or something. So I think of him as the stereotypical “bad boy”, the amorous slacker with a heart of gold. Sakuya has a very stiff, posh nature, and the game stresses that he’s this perfect manicured Nobleman, so I imagine him pretty in kind of a fine-boned French way.
Shuu: Everyone calls him fatbird, he’s gotta be a chubby dude. The bird has markings that look like a goatee and male pattern baldness. The character is a creeper. The bird has an especially nose-y looking beak that doesn’t translate well into typical Japanese facial features. However, Chukar partridges are native to the Middle East, where aquiline noses are more common, so I went with that.
SOME OTHER CHARACTERS I WAS PLANNING TO DO;
Azami as a stout Indonesian woman because Java finches are stubby Indonesian birds!
Blaster as a scrappy androgynous Japanese biker with bleached hair because lutino budgies don’t have pigmented ceres that differentiate males and females like regular budgies!
Nageki as slight, shy black kid because the main character remarks on how rare mourning doves are in Japan and talks about how they’re more common in America!
Urushihara as a small, well-dressed, distinguished older Japanese gentleman!
Ryouta as a feminine-side-of-average Japanese boy because he’s always getting jobs that involve cross-dressing!
Kazuaki as a gangly, awkward Japanese man with stringy slicked back hair because fuck that’s a weird looking quail!
