Romantic Dark

I will exorcise all that has cursed you. With his band about to make its major debut, Neo's present problem is his terrible misfortune. He got in traffic accidents three days in a row, he lost his wallet in a burglary, he developed a mysterious fever, and he kept falling down the stairs... To escape all these disasters, he was ordered to go get an exorcism. When he arrived, he found a lovely young girl—Yomi. "I'll help you find the mystery of your destiny." With those words and a sparkle in her eyes, she barges into Neo's life. (Source: J-Publishing, translated)
