Entirely off-topic but I swear this game series is getting the same treatment as Guilty Gear. You get a game with the soundtrack, and a damn good one at that! I'm excited for the next arc!
Not permanently, no. Every sinner in the game has E.G.O in some form, but it is not ‘effloresced’ like the E.G.O of xiao, Angela, etc, but also isn’t like the E.G.O equipment of lobotomy corporation.
While there is no official name *yet*, a name I’m a fan of is ‘budding’ since this whole game seems to just be the sinners overcoming their flaws, therefore moving closer to effloresced E.G.O
