A roar struck Alkeides’ ears.
It signaled that the police officer called John had poured all his strength into a desperate strike... and by the time it reached his ears, John was already upon him.
The blow momentarily broke the sound barrier.
It created a shockwave that sent Flat and the nearby rubble flying.
It took just an instant.
An impact ran through Alkeides’ side, feeling so weak to him that he almost doubted it.
It may have been a supersonic blow from a prosthetic hand transformed into a Noble Phantasm, but that was all it could do to Alkeides’ superhuman physique.
As a matter of fact, the impact had broken off the prosthetic hand’s blade at the base and the recoil had sent John tumbling to the ground several meters away.
But it had been enough.
John had put all his might into that blow of his prosthetic hand—a thrust of a blade dripping with hydra venom.
It would have been a fatal wound to almost any Heroic Spirit... but there was a reason it ate into Alkeides’ Spirit Origin with especial ferocity.
Death.
The pure curse of deadly poison.
The thing that had once driven Alkeides to end his own life coursed through his veins.
As it entered his body, Flat spoke the phrase that concluded his spell, signaling that his stratagem was complete.
“...Game over.”
