Animetal Marathon IV (アニメタル・マラソンⅣ Animetaru Marason Fō) is the fourth full album by Animetal. This album focuses on the theme songs of anime from the 1980s. It also marked the return of Animetal after a two-year hiatus. However, it was also the last to feature lead guitarist She-Ja, who was then replaced by Syu on the band's subsequent releases. This was the band's only album released by Cutting Edge Records, a division of The Avex Group.
