DR. STONE - Chapter 16 - Kohaku

lol Amber/Kohaku is in love with Senku. Still blue-eyed half-japanese is impossible. Manga authors do this half-japanese that look like entirely different ethnic groups stuff because “something that’s different but only a little bit different is easier to accept”. It incredibly racist and scientifically unsound.

Putting all that aside. I’ll let the blue-eyes slide since it is possible after 4k years of a inter-breeding. However, their speaking dialect should have considerable change over 4k years, to the point of being nearly impossible to understand. Especially without books that standardize the language (dictionaries).
