角醒ハンター オメガホーン

Shout of Flame (Sei Narahara), a treasure hunter well-versed in ancient scripts, spends his days deciphering ancient manuscripts, setting off on expeditions and unearthing ancient artefacts. One day, whilst at an ancient ruin, Shout discovers the ‘Horn Awakener: Omega Horn’ and ‘Egorgia’. Although puzzled by the Omega Horn—which differs from the Horn Awakener used by modern hunters—he tries setting the Egorgia into it, only for a gigantic horned beast, the Flamehorn, to appear!

The Flamehorn recognises the qualities of a ‘King’ in Shout’s ego (i.e. his unwavering resolve to follow his own path), takes the name ‘Captain Omega Horn’, and demands that Shout fight alongside him…!?
