Nomanalive

Sam Sanderson is envied by many for his job, however he himself didn't seem to like it much.

Due to his expertise in nanotechnology he was tasked with monitoring the state the Valkyries, humanity's strongest weapons who all just happened to be made into gorgeous females.

Forbidden from even touching any of them, Sam spends his days in agony watching flowers he couldn't hope to touch. However one day all of that seemed to change.

His luck recieves a massive boost, but with it came new dangers, more responsibilities and conspiracies knocking on his door one after the other. 

Finding himself diving head first into an inter-dimensional mess, Sam realizes that sleeping with robots was the least of his concerns.

Valkyrie Smash

"But seriously, how did you do it, Doctor?" Venti asked. She had landed near them a few seconds ago but remained silent, enjoying watching Nino receive her punishment.

"Ah," Sam turned to look at the orb in his left hand then answered. "I just copied something I saw in the recordings of the previous battle."

The orb itself was a spare Valkyrie heart he had brought with him just in case. Using it he's able to create preprogrammed formations of runes, just like what he did when he discovered how to modify hearts for the first time.

"I noticed that the guy named Perseus never created a halo of his own and instead used his staff." Sam explained. "I concluded that, if he had to rely on tools to make use of the runes, anything he used most likely didn't require any mental power, which also meant I could copy it without a problem."

I just copied something.
