Spira Spica performing The Hidden Dungeon Only I Can Enter theme song — ‘PYRAMID Daigyakuten’

Japanese pop rock band Spira Spica will be the artist performing the opening theme song for the upcoming new anime The Hidden Dungeon Only I Can Enter it has been announced this week.

The theme song is called ‘PYRAMID Daigyakuten‘ (aka Pyramid Great Reversal) and, while a sample of the song has not yet been released, it is highly likely it will be a powerful one.


Especially when you consider the music Spira Spica has provided for hit anime series in the past.

Those songs include powerful themes for Gundam Build Divers and Gundam Build Divers Re: Rise Seasons 1 and 2, as well as the ED for Warlords of Sigrdrifa, the ED for Ao-chan Can’t Study! and the opening theme song for Do You Love Your Mom and Her Two-Hit Multi-Target Attacks?
