Shitsuraku no Miko

During a rare visit to his estranged father's grave, our hero catches a glimpse of a "phantom girl" that he vaguely recalls from dreams. Dismissing it as a late-night hallucination, he returns home, hoping to resume his peaceful college life. But the ethereal woman follows him, introducing herself as Raine—and only he can see her. As they begin to coexist under the same roof, his tranquility shatters as the landlady, her daughter, the grave keeper, a professor, and others pry into his new reality. Who exactly is Raine?! From White Masq.
