I'm glad you're enjoying it! :)The kunoichi won't be moving into the Manor - I mean, would you if you had that awesome hot spring to hang out in, way away from all the nasty war stuff going on? ;)
That's a good point, but will they be making another appearance since they are so tight with grandpa and now with you?
Absolutely, yes. In fact there's a strong hint as to their involvement during a certain character's action-filled re-introduction...
