IIRC this is what happens if you pass by the two of them in the arcade game when on your way to meet your new kanmusu. Jintsuu greets you while Sendai just go on doing her stuff =3

Seconded, I also recollect that as well. They should really make a "walk through my naval base" feature for the browser game sometime down the line. That would be insanely dope.

Really, Sendai.
