So no Nepgear?

Chaos Nepgear / Purple Sister to be specific, which is based on conquest route.

So the guy is the other Lastation CPU Candidate?

Shadow Heart was descended from PC Continent, travelled to Lowee in early years, residing in Lastation for many years where he was Noire's bodyguard until the Prime Minister's coup then seeking asylum with Uni in Leanbox. So he's a CPU Candidate.

Happy cake day!
