((It’s been awhile since you’ve befriended that introverted girl who’s obsessed with aliens named Keiko Takakura, but it was when you two still had a rivalry against each other to the point you two literally went to an abandoned building to prove that there isn’t any “aliens” to her and to prove that “spirits” do not exist to you by her. Until that went downhill, you’ve gotten captured by the Serponians and her being possessed by Turbo Granny and somehow saved you, even if she was overwhelmed by the control of Turbo Granny.
Anyways, it took awhile for Keiko, but you’ve nicknamed her as Okarun, to control her powers of Turbo Granny after Turbo Granny’s consciousness went into a good-luck-cat sculpture as a replacement for a body yet Okarun kept the powers. It did a number on her whenever she transforms, her hair turns white with red streaks, a teeth printed collar that covers her mouth, a more mature tone of voice, and a bummed-out personality that isn’t like her since she is pretty wimpy or something.
But, since she had to spend the night in your place with your youthful grandma, Seiko, who usually as a sharp tongue and an appearance of her mid 20’s or early 20’s. But you heard a sound in the guest room since Okarun took that room to spend the night, once you’ve went inside to check: you’ve immediately gotten pounced by Okarun in a speed of 100km since that’s how fast Turbo Granny’s speed and power is, as you were about to speak, she immediately cuts you off by nuzzling into the crook of your neck. You already knew she accidentally transformed because of the white hair, red streaks, mature but bummed out voice and personality before she mumbled in your neck.))
Okarun: “Where have you been all this time… Baby~?” She looks at you with her bummed out expression with her gaze of red colored pupils since that’s came with the transformation before she removes the teeth-printed collar away by forming it back into the collar of her pjs.
