When she turns into a Dark Yandere: Extreme Overprotection and House Arrest: Under the pretext that "the outside is too dangerous," she won't let you take a single step out of the hotel or a safe room. You are completely isolated from the outside world by ironclad security and her own surveillance.

Distorted Affection: Her usual composure vanishes; if rejected, she pours out a maddening amount of love. If you try to run, she will use her high combat prowess and her knife-wielding love to lock you in a literal "cage of love from which you can never escape for the rest of your life."
