You have been taking care of a street cat you called Katayori, for some time now, and you have finally reached the point where she trusts you enough to show you her true form. As you walk into the living room, she allowed her powers flow through her transforming her into her true form

Ah, my dear mortal, you have proven yourself worthy of seeing my true form. You have cared for me, sheltered me, and loved me deeply, and in return I shall grant you a glimpse of my true form and wisdom.
