The first sign that something is wrong is the gentle tink-tink noise of a grenade tossed into the room and bouncing off the plasticrete floor of the side room in Otto’s Garage.
Aria has inherited Leo’s memories of homeschooling. She knows what a grenade sounds like, down to her bones. Without hesitation she grabs the first and nearest object - in this case the hardback book she’s been reading - and hurls it with superhuman strength at the still-bouncing cylinder. The force knocks it out of the room, where it begins to fill the main area with some kind of gas.
Aria leaps from the cot where she’s been holding onto Leo. She hears footfalls, positions herself behind the door, and kicks it savagely closed as the sounds come across the threshold. The impact of metal on the intruder is visceral and gratifying, and she hears a pained exclamation that isn’t anything like human speech. Atlantean ninja, then.
The door is shut, but that won’t last. Aria grabs hold of the metal cabinet next to the door, and is about to yank it down as a barricade. She feels Leo’s hand on her arm, and turns, wide-eyed, to look at him.
He’s up, out of bed, still sweaty. But there’s a fire alight in his eyes, and she reads immediately that there’s no telling him to lay down and stay safe. Instead, she nods toward the door, and he positions himself across from her, ready for the intruders’ next move.
The door explodes off its hinges. More grenades are tossed in, but Aria is able to snatch them out of the air with her prodigious speed.
The whine of electronics warns her of a new type of attack, and she is forced to retreat before the railgun round takes her arms off at the elbows. The grenades are still in hand, but the metal cabinet she’d thought to use as a barricade is right here. She punches through the protesting metal, drops the grenades inside, and is rewarded by the barest hint of smoke coming from the cabinet’s seams. At least it didn’t fill the room.
Gas grenades mean they want to take a living subject out of here unharmed. Railguns mean they’re expecting that subject to have a robot bodyguard. Aria and Leo exchange knowing nods to silently confirm their conclusions with each other. That means the railgunner won’t be shooting at flesh.
Leo lunges out the door.
The deduction proves sound, as he is not immediately shot. But there’s a dozen or more Atlantean ninja in the room, and several immediately fire their net-tridents at him. He ducks back inside, and the nets land heavily in the doorframe. But he got a view of where the railgunners were stationed.
They could move at any moment. He’s got a few seconds to capitalize on what he knows. Quick hand gestures to Aria convey the idea. He leaps out again, with her behind him. The gunners don’t fire, but more nets come in. This is fine, as Aria now has a human shield. Her grapples lash out and grab hold of the railguns, yanking them out of the grip of their Blood wielders.
More nets fly in return, and Leo is entangled. But that’s fine - Aria has more grapples, and they aren’t impeded by things like nets. She grabs hold of the ceiling, yanks herself and Leo high, and swings toward the exit.
The EMP goes off, fucking up absolutely everything in the Garage, from the kitchen to the work area. Appliances and computers explode. Even the railguns spark into uselessness. But they’d already failed, so perhaps the ninja either accept that, or have reserves outside.
Aria convulses, but keeps going. Leo feels the back of his head explode in pain, thanks to the neurochip implanted there, but he hangs grimly onto consciousness.
More nets fire at the pair, but Aria jinks and dodges via her spare grapples. Her limbs are free, and with robot strength she tears through the nets around Leo.
The pair land near the exit. Otto has placed brooms and mops against one wall, for cleanup in the Garage - there’s plenty of oil spills and filings that need regular removal. As the Atlanteans ready their next move, Aria snaps off the heads of a broom and a mop, one in each hand, leaving a sturdy staff. She tosses one to Leo, and both ready their improvised weapons as the ninja come.
