As the guide suggests:
CHARACTERS WITH NO CONTENT AS OF NOW
NORAH (Alice’s mom) Found at the church.
NADIA (Pool Safeguard) Found at… you guess it, the pool.
Any other's not mentioned are from incomplete or dropped quest/event ideas. Posting them will only confuse people or mislead them to think these events will happen. Nobody is going to be upset with you poking in the Unity data, but please do not post them on itch.
