It's gotta end up being three. No way Chris doesn't fight her way back, and Serena seems like she's one noble plot away from jumping ship.It's actually a nice joke in this series' case when Hiro wanted to stay away from nobles, to avoid getting tied into their power plays and politics, in order to remain an unfettered mercenary. Instead he's associating with them all the time, receiving awards granted by nobles/royals, and even his harem turns out to include a noble daughter. Or possibly two.
