Just put the name in Google Translate, and from the sound of it the name of the Gundam might be Gundam Flauros or something like that.
Gundam Fraurosu or ... Gundam Flawless?
Is "Flawless" a demon name? Nope
It's Flauros, as previously stated. Expect the full name to be ASW-G-64 Gundam Flauros, since Flauros is the 64th demon in the Ars Goetia.
It should be Flauros according to Ars Goetia wiki
