This would be the followup to 2011's The Enemy Inside, which was the last album to be exclusively released in Japan, and the predecessor to 2015s Vena.

The Revelation would serve as a departure from their earlier punk rock sound from Final Destination and The Enemy Inside, which instead got heavier and was more influenced from metalcore on the album that tracks a little over 43 minutes long.

Following the release of the Through Clarity extended play in 2012, the band would go into the studio with David Bendeth once again to record the followup to The Enemy Inside in December 2012.

[8] The band would end up doing an exclusive acoustic Christmas performance of "Carry On" in the studio to showcase the progress of the new record.

[17][7] The debut worldwide studio album, The Revelation, received a polarised response from critics as a whole.

The main praises for The Revelation consisted of the melodies and clean vocals by frontman Masato Hayakawa.

Max Barrett of Rock Sound, who rated the album a 6/10, noted that: "With the quality to fuse a mature, melodic approach with their ear for a clean and catchy chorus ("Given Up On You"), the Nagoya-based quintet make it virtually impossible to simply sit still and listen.

Chuck in the more venomous, metalcore-esque sections (the title track), not to mention the odd ripping solo ("Time Bomb"), and there’s enough variation here to formally introduce Coldrain to the world.

"[18] This point was reiterated by Kersten Lison of Twilight Magazine, "The metalcore is extremely dynamic and energetic.

"[22] Many of the songs were strongly praised by DJ Robintje who wrote for Avo-Magazine, who would comment on the anthem like sing-a-long "The War is On".

"[21] However, on a more negative review, Rasmus Peters of Metal.de would highly criticise the lack of originality on the record as a whole.
