Amamiya's whole body felt like it was on fire. Correction: it was on fire. Her eyes closed from the pain, and Akiha's voice sounded in her ears but it seemed like a million miles away. She felt herself being hoisted into the air...

Let your big sister take care of everything, the voice in her head said, and she gave into it.

Her skin tone instantly darkened, and the expression on her face changed from one of pain to one of glee. She actually giggled, despite everything, and then used her Burst powers to block the flow of heat away from her body, turning off the tap fueling those fires.

"Don't care~" Abyss - for it was Sakurako no longer, her alternate personality was in the driver's seat - sing-songed. And then a pair of blades grew from her back, whipping around like scorpions' tails to slash at Akiha.
