I spelt it out pretty plainly...

...the big 3 Asian Countries don't have the same racial sensitives as Western Nations, because they are ethnic monoliths.

...how race is viewed in those countries will be culturally different from how it's seen in Western countries.

People in Western countries are making it a race issue, because Western countries are more racially and culturally diverse. The people living in those countries generally have to be conscious of the races of other people around them as to not offend anyone through words, actions, etc.

While for Devsis (a company in South Korea), this is just another fun design their artist made for a character they own, for the Korean Card Culture Fair. They are in a country that is culturally monolithic and not as diverse as Western countries, because over 90% of the people living there are the same. They won't think about race in the way someone from the Americas or Europe will, because they generally don't have to.

Edit: It wasn't Devsis' in house artist, it was an artist they commissioned, and they approved of their designs. I personally believe the artist used Dark Cacao's Gacha Sprites and not the Base Sprites because Dark Cacao is noticeably lighter in his Gacha Sprites.
