[Comprehensive] Negative Wishes

Hello everyone, my name is Quan, and I am a bird that can make wishes come true. Yes, that's what you guessed. I am the gas life form from the dark continent, known as one of the five major disasters - Ai! Due to an accident, I not only got a human body, but also fell into a different world. As a rare mutant in Egypt, my diet is much broader than that of others of my kind. Desire and strong human emotions are my food. Although their energy is slightly inferior to that of life, eating them several times is enough to fill my stomach. I am the goodwill ambassador to mankind in "E". But unfortunately, humans in this world are not friendly at all. There are always many humans in uniforms calling me "ghost" and then trying to chop off my head with knives. I'm just eating a little emotion! At best, I can only make people angry! I! No! Eat people! That short guy with black and green gradient hair! You have been chasing me for three towns. Can you calmly listen to my explanation? (Privately set up a mountain of early warning.) (It is assumed that the protagonist and Naniga are both Ai, I hope Togashi will not slap me in the face.) Intention: goodwill
