Mutsumi lurches forward a little as Jamil lets go of her arm, and her eyes widen as the light fades from between her fingers. She opens her hand to see an unfamiliar cell phone charm decorated with stars, and as the world still seems to be playing in slow motion, she stares at it in blank confusion.

Then, with a sharp intake of breath, things click into place. She moves on some newfound instinct, like a girl possessed, getting shakily to her feet as she closes her hand tight around the charm. She raises it over her head and calls out in a voice that sounds too far away to be her own, "Supernova...shine on!"

The world around her flashes bright, then runs black as all light leeches away. It's cold, but she feels safe, like arms around her shoulders — and just as she begins to think that, the darkness erupts into a panoply of light and color, dazzling her vision. Though she feels lightheaded at first, she's oddly steady on her feet, and by the time the light fades and resolves back into the real world, there's a strange clarity of purpose that staves off the paralysis she'd usually be feeling about now. She feels different — and at a glance down, she looks different. She can feel a mask obscuring most of her face. Just as she's getting her bearings, new light takes shape between her hands, and after a moment she feels the weight of an electric guitar in her grip, the light fading to a bright pink. Her eyes widen a little further. It looks so much like her guitar at home. 

Time is starting to speed up again, and she knows she doesn't have time to act. Jamil is still down, and if she can do anything...

She can. She can feel it. Just like with the transformation, the words seem to come from somewhere else. She strums out a chord, then another, a haunting lulling that turns to pale smoke as it leaves her guitar.

"Somnus mortis."

It'll slow down the boba monster...but it won't be enough.
