Koroshiya can only eliminate bosses related to the main story.
Fiji is a sub-event, so it cannot be defeated.
If you absolutely cannot clear it, look for the Shake Shop in the fake space.
What is the fake space? And what will the snake shop do?
Sorry, I missed your comment.
The fake space refers to the hub area in front of Basel Castle.
Who is Koroshiya, and how does this affect the main story? Like, are there different cutscenes?
