Leviathan リヴァイアサン/終末を告げし獣

Leviathan リヴァイアサン/終末を告げし獣 (Leviathan/The Beast That Tells of the End) is an image album released by Absord Music Japan and momo+grapes on March 2nd, 2005. With 10 tracks, it retells the story of the horror manga リヴァイアサン, written by Eiji Outsuka (大塚 英志) and drawn/illustrated by KINUTANI Yuu (衣谷遊). Serialized by "Monthly Dengeki Comic Gao!", it spans 12 volumes and was published from 1999 to 2005.

The manga takes place in a future version of Tokyo that has become ethnically diverse, with many refugees and immigrants coming from all over the world. Many supernatural and psychic occurrences happen. The shamen 三溝耕平 (Samizo Kohei), after being missing for years, returns with their four colleagues. He comes with a prophecy telling of the beast of the end. However, they have all been mysteriously stitched together, with each body part retaining their personalities. He returns to his home in Shinjuku-ku (新宿区) where he works as a psychic healer for an unlicensed clinic. Soon he becomes a sort of mystic detective, solving paranormal mysteries with aid from several human/sub-human allies. The world at large, his friends, his enemies, the government, and the poor immigrant class wonder if he has come to prevent the prophecy's apocalypse or to fulfill it. The author uses his knowledge of urban legends, occultism, and 手塚 治 (Tezuka Osamu)'s manga, hiding Easter eggs and homages throughout.

The Image Album features five vocalists, Sizzle Ohtaka. RIKKI, Aramary, Hawk Spencer, and Geila Zilkha. This was the first work RIKKI collaborated on with Revo and the last work Aramary collaborated on with him. It also featured 若本紀夫 (Norio wakamoto), who would later appear on Roman, Moira, and Nein, and ゆかな(Yukana), who would appear on Roman and Moira. This was also the first work to feature 斉藤"jake"慎吾 (Shingo "jake" Saitō), a staple in later releases.

On December 9th, 2020 the album was reprinted by KINGRECORDS. It retailed for 2,800 yen and had a catalog number of KICS-3965.
