Of course, they never saw that. Even though humans are classified as weak creatures, they have high self-esteem, so they are reluctant to eat each other or even wrena just to become wrena and be free from the curse of racism.

Even though there are not a few types of humans who dare to do that in order to mingle with Wrena and release their suffering.
"They will feel a complex change," said Wiralaya as he sprinkled something on the head of the sleeping man in front of him in his palace on earth. "Initially, they will start to get addicted to the taste of the meat; they will start rejecting other types of food because their sense of taste has changed; and eventually, they will greedily eat each other in order to quench their thirst."
