"Sis, here's the thing..."
In response to her sister's inquiry, Alice didn't have much to hide. She simply explained the course of events.
The story actually started with a research lab attack that happened a month ago. The perpetrator of the attack still hadn't been caught to date, even though Alice had been working overtime with her team for so long, the case hadn't made any progress.
The attacker was clearly a pro, meticulous and efficient, leaving not a single piece of evidence at the scene of the crime. Alice even resorted to magic, unable to deduce anything useful. She sought help from a senior in the Divination Department for a divination, but the answers were obscured by fate itself, leaving her with nothing but loneliness.
