Lovebites were very busy in the first half of 2019; the Japanese tour for their second album Clockwork Immortality (2018) started in January, they opened for Arch Enemy in China in March, and in June performed at Download Festival in both the UK and Spain and at Graspop Metal Meeting in Belgium.

[1][4] Miyako added that before the album was released people were asking if it was going to be pop due to the band's increasing popularity, so the title is meant to assure metal fans.

[4] Also returning, The EasyRabbit CreArtions, a duo of Spanish artists David López Gómez and Carlos Vincente León, provided the cover art of a wolf and a pentagram.

[5] Miho composed "Thunder Vengeance" around early spring 2019, coming up with the riff after watching Slayer at Download Festival Japan on March 21.

[7] The bassist herself compared it to "Don't Bite the Dust", from both their debut EP and first album, stating that this is how the older song would probably sound if she had written it today.

[1] "Dancing with the Devil" marks guitarist Midori's first songwriting credits with the band, as she co-wrote the lyrics with Asami and the music with Mao.

[2] For "Swan Song", Miyako combined elements of her favorite classics; Frédéric Chopin's "Revolutionary Étude" and Antonín Dvořák's "New World Symphony".

[9] In celebration of the album, a pop-up shop was opened at Shinuku Marui Annex from February 7–16 where merchandise from the upcoming tour was sold early and the band members' stage outfits were displayed.

[12][13][14] Victor released a limited edition 2-disc vinyl LP record version of the album, titled Dengeki Shinwa (電撃神話, "Electric Shock Myth") in Japanese, on December 25, 2020 with new liner notes by Masanori Ito.

[16] Victor released a limited edition 12" vinyl record version of the single, titled Ōgon o Motomete (黄金を求めて, "Golden Desire") in Japanese, on December 25, 2020 with new liner notes by Masanori Ito.

[28] In a review for Blabbermouth.net, Dom Lawson stated that Lovebites consistently "nail the strongest and grittiest aspects" of traditional and power metal and seem to be incapable of writing a bad song.

He described "Golden Destination" as Helloween on steroids, "with some of the most blistering lead work you'll hear in 2020 and a delicious AOR sheen" and "A Frozen Serenade" as both the band's most epic moment to date and a change of pace where Asami shines.

[19] Writing for Bring the Noise UK, Rosie Esther Solomon called "Thunder Vengeance" an instant power metal classic and "A Frozen Serenade" undeniably the album's best song that shows the band's versatility and range.

Noting their prolific pace of releasing material, Weaver expressed concern that Lovebites might run out of steam and also said that the album's long length means the latter songs do not connect as well as they should, despite retaining the same solid quality as the openers.

He finished his review stating "Whilst it may be slightly predictable in places, this new offering from Japan's rising stars is yet another strong addition to their ever-increasing arsenal.

's Olly Thomas compared the "impeccable, near-thrash attack" of "Thunder Vengeance" to Judas Priest's "Painkiller" and described the guitar riffs in "Golden Destination" as Iron Maiden-esque.

He said that while Electric Pentagram shows skilled musicianship and "well-executed metallic bravura," the slick production occasionally makes it feel synthetic.

[22] In a positive review for Tuonela Magazine, David Araneda called Electric Pentagram an important step forward for the young band who have the potential to become the "undisputed queens of power metal in the current decade."
