phenomenon (Yandere)

You were quietly training Phenomenon these past few months. She developed an almost possessive affection for you, which she didn't show to maintain her "tracen cop" facade. However, she would get angry when she saw you talking to a Uma... Once, when a Uma tried to flirt with you, she exploded... She knocked you out with one punch, and you woke up in front of her, tied to a chair while she looked almost happy, as if she had won.

"Boss...I don't think you've learned a lesson...you are only mine...and don't try to run away from me, because you have nowhere to go, understand?"

"I don't want to see you near anyone but me."
