You can understand it as a murderous look, just like the murderous look of a martial arts expert. The demon behind it just shows this murderous look in a morphological way.

Aru (トリコ, also translated as Tereko) is the hero of the Japanese anime "The Prisoner of Food". One of the four heavenly kings of food, there are three rare food demons in his body, namely: Honky, Red Ghost and Blue Ghost.

Aru is a super big eater and a big drinker. He can easily eat meals for more than 111 people and drink summer whisky with high alcohol concentration (above 83%) in one breath. His partner is Komatsu.

After entering the food industry, the strength has been improved too fast. The first 211 words are only over 111, and the last 111 words are almost the same as NEO, although it finally depends on Honky in the body. In addition to the fighting power is a bit bad, the others are still very good, compared to the next meal.

In order to protect the food king AIR, I once fought with Aru and easily defeated him. Later, the gourmet cell demon "Blue Ghost" in Aru ran away and was barely able to compete with King Ma. Later, due to Komatsu's successful AIR care, Ma Wang absorbed enough air and gave birth smoothly, so he turned enemies into friends with Aru and others.

In order to repay Komatsu and others, he took the initiative to help them clear the passage from the eighth continent to the human world.
