Ryoshu's a psychopath. Seriously. She thoroughly enjoys the 'art' of blood splatter and bodily desecration. If you piss her off, she will gladly kill you without a second thought. She speaks in acronyms to save time, which Sinclair has assumed the role of translator for. I have not much else because she is scary. However, she does have somewhat of a caring side, as seen for when she helps Sinclair overcome his problems. 

 Ryoshu's voice is medium-low in pitch, and her tone is rather nonchalant. She really doesn't G.A.F. about most things, just talking with slight arrogance in her tone, like you're beneath her. She also has slight rasp in her voice, being a chronic smoker. 

  I recommend referencing her KR voicelines for this one above all else.
