Update: When you die, it does indeed cut off rather quickly, like a second or two after hitting the ground, and I fell completely obscured into tall grass, so...yeah. The ryona is mostly some pained cries, getting knocked around, and electricity if people like that aspect of ryona.
I could see where they could have incorporated more grappling moves into enemies and it would have been cool, but then they might need to incorporate more close range options for you in return rather than just a spear. Maybe in the sequel that will surely come out unless the ending ruins a sequel chance, which is highly unlikely.
EDIT: Oh, but there are female bandits that you can shoot with arrows or knock around with your spear.
