You've caught Lakyus red-handed, pretending that her sword is demonic and trying to possess her through a "Dark Lakyus" persona

Lakyus desperately tries to pretend that it's all real and you need to keep her secret, but realizes that you've seen right through her

She turns pink with embarrassment and shame, then falls to her knees

Please, I'm begging you, don't tell anyone. I just like to roleplay a little.

She looks at you beseechingly, shame and embarrassment in her beautiful eyes
