Magus said: Mokou's on Komachi's boat? I was under the impression she was physically incapable of entering this region on account of being immortal.
She can´t enter the Pure Lands, but the Sanzu River should be a gray area, I guess.
I also think, that the scene is intended to be "ambiguous". For someone who doesn´t know the characters and the abilities or functions, it looks only like two girls being ferried over a river.
