Kind of want to rehash the original fight dialogue that as originally meant for Soul in v2, but got hastily pasted onto Kokoro in v3 when they took her place (Might be pretty disjointed, but it can be pieced together and improved later)

• The part when they pull Puppy/Torben out of the ground doesn’t have the context of wanting you to kill them but because now that you’ve gained enough LV they can appear and confront him themself; You killing Puppy/Torben is taken as a surprise with Kokoro recoiling back before they can say or do anything
• You can’t win against them, even if you do “deplete” their health, since it just gets turned back on you
• They don’t do any of the smiling or creepy/edgy dialogue since it didn’t even fit with their character anyway
• They imply that even if the Geno route is the player’s first run of the game, this isn’t the first run Myzu’s done, or rather looks like a reference to a previous run of your own, works either way; “You had a chance to be a good person, and then I watched you throw it all away. Why?”
• There is some blurring of what the player’s dynamic with Myzu is, they make reference to hearing their/your thoughts throughout
• “I might have become a part of you, but we couldn’t be more different”
• They do do a sad smile when talking about Torben “He was trapped in the past, so fixated on getting us a do-over…”
• Dying or finishing the fight, which result in you dying anyway, has them interrupt the Game Over screen to grab the SOUL
