Foreigner: I Use My Eyes to Exchange Light with the Devil

This person is originally a guest from heaven, wandering into this human world. The human race in this world is declining. I am a pure-blooded human being, and all sentient beings regard me as nothing more than an idiot. Fortunately (or unfortunately), I met a "devil" who made a deal with me. I give it treasures, memories, emotions... Even these eyes. It gives me strength, longevity, knowledge... And the ability to see the true face of this world. When our eyes are forever plunged into darkness, the "truth" in the world is brighter than ever. It turns out that the suffering of all living beings stems from the "light" above our heads. ——This is a story about loss, transaction and rebirth.
