I've found the way to meet Mikail in day 3 without getting killed:
- Go to the study, choose "Browse the books" (save before you choose), make sure you are reading a book mentioned about thread (this is very random so I have to save/ load a lot)
- Then go to the training grounds, choose "try to do magic" to complete the mission about improving threads.
- After that, just go to the forest and choose "use vision thread". This time Noctisee can dodge the knife and survive.
However, I'm stucked at the reading in day 4. Although I have visited all the places, I can't complete the reading mission
P/s: For the thread mission in day 4, make the same steps in day 3
