Testa-Rossa, the Vermillion Knight (《緋の騎神》テスタ＝ロッサ, aka no kishin tesuta=rossa), known in legends as "a crimson demon said to wield a thousand weapons", is one of the seven Divine Knights of Erebonia. It was found in the depths below the Imperial capital Heimdallr, where it was sealed away after the capital was recaptured by the imperial family in the fifth Century.
