When Erica Aurelia knew that Ann will come hunt her if she dies, Erica realized that Ann didn't come after her for revenge, but she came back because the spirit, Zaratan, wanted the Aurelias to be dead.
The spirit later on realized that he wasn't killed by his creator, but that the creator was killed separately from him.
given the fact she was killed three days after getting the game, and she was only able to capture two main leads in game.
When Klaus Harvan, one of the main leads, venture through the Ruins of Visitor, Erica thoughtfully collected wands and items she knew she'll need when going into the unknown.
I mean there's a bathtub scene with one of the oldest girls in the group, but I like the fact that the main character didn't overly exaggerate and just kept calm.
He literally kept calm enough to deceive the girl which I find adorable because of their relationship XD
and if anyone's curious, read through around Roslia arc (maybe ch10 to ch18)
