Hoshikuzu no Ring (星屑のリング)

"Hoshikuzu no Ring" (星屑のリング) is a single by Asami Imai and the opening theme for the 2012 OVA Corpse Party: Tortured Souls, part of Corpse Party (コープスパーティー). Released by 5pb. Records on July 25, 2012, it became Imai's 10th single, with "Days" issued as its B-side.

Built as a polished J-Pop theme, the song pairs a clear, steady vocal line with a melodic rise that gives the chorus a luminous pull. Tsukasa composed the music, while Imai wrote the lyrics, and the writing emphasizes contrast between a clean pop surface and an undercurrent of tension.

That balance suits asread.'s OVA adaptation, which traps a group of students inside the cursed Tenjin Elementary School. The song's brightness works as a sharp counterpoint to the series' claustrophobic horror, framing the opening with unease rather than blunt aggression. As a release, it reached No. 26 on the Oricon Weekly Singles Chart.
