Frontiers (Psycho le Cemu album)

The CD contains "VISITOR", the ending theme to the anime コロッケ!(Croquette!).

The first press of the album came with a random figurine of one of the band members in their costumes from the "Ai no Uta" single.

Several songs were previously released as singles: Gekiai Merry-Go-Round and Shunkashuutou originally appeared on the Gekiai Merry-Go-Round/Shunkashuutou single; Roman Hikou and BLUE AGAIN appeared on the Roman Hikou single.

VISITOR was released on a single under the alias of サイコロ・コロッケ(Saikoro Korokke) containing the opening and ending themes of the anime コロッケ!(Croquette!).

Ai no Uta and Aquaria were previously released on the Ai no Uta single, but the versions that appear on the album are new remixes.
