WMG / Shadow Hearts

The Koudelka manga takes place after the ending where she beats the Final Boss.

  • Koudelka is emotionally scarred, but stronger and more independent.

Both good and bad endings for Shadow Hearts and Shadow Hearts: Covenant are all canon

  • Shadow Hearts: Covenant: Some people believe that the proper play-through is first game: bad ending, second game: good ending, first game: good ending. It helps if you prefer the many-worlds explanation of time travel. This has a benefit of explaining Anne's Cross. Yes, it goes through a time loop, but it's only a single (open-ended) one. Others wonder why Anne's Cross doesn't get more battered with every loop, apparently thinking there's a stable time loop going on.
    • This comes with the added plus of providing a solid premise for another legit sequel starring Yuri.
    • If a sequel is possible, it could have the diverging point where Yuri and Alice meet Karin.

Koudelka turned Yuri into a polyglot

  • Yuri seems decently intelligent, but not book smart or studious, and is always moving around too frequently to pick up languages through naturalization. Despite this he can walk up to any man, woman or child in the streets of Tokyo, Paris, Wales, Chengdu, Florence, Moscow, and many other places and strike up a conversation. This is because while Koudelka had access to Yuri's head she shoved a ton of language comprehension in there, so any time you're talking to someone in France, it's in French and so on. She didn't bother to give him multilingual reading comprehension, though, probably because the more she messed with his head the more painful and dangerous it became for him, hence his persistent confusion with Russian lettering.

Unhanded style Edwards were the basis for Yuri
It's become a thing where Edward is the frontline DPS and tank and in a game where weapon durability is random, it was easier to just have him go barehanded even all the way up to the final boss. That ended up being the basis for why Yuri uses fists as a weapon.
