>Frieren is anime equivalent of Tolkien
This is silly statement. Tolkien created the basis for modern fantasy. Dungeons and Dragons, Witcher, Song of Ice and Fire, Warcraft, etc., are based on Tolkien's works. He introduced elves, dwarves, and other archetypes. Tolkien created a vast world based on Celtic, Nordic myths and legends, and Christianity. He created several languages used in Middle-Earth.
Comparing Frieren to Tolkien is silly. Frieren is a generic-looking (as well could be AI generated) anime full of fanservice.
