Kimagure Temptation 2: Yuuyami Kaikitan

After the economic collapse, cheap second-hand properties in an abandoned housing development attracted buyers who then disappeared without a trace. The development became a literal ghost town, the area enveloped in a thick and unnatural miasma. When the police reached the limits of what they could handle, the Onmyōryō agency — which manages and eliminates non-human entities — sent the young onmyōji Haruhisa Tatsumi and his partner, the demon Anneliese, to investigate. The moment they arrived, a bizarre phenomenon charged with intense malice made it clear that this case was not ordinary. Something of extraordinary power was behind it. Haruhisa, armed with a mystical katana capable of cutting through unseen threats, steps with Anneliese into the Reverse World — the hidden realm between the present and the eternal.
