That “human”, Aleister Crowley, had a few pieces of magic viewed as great achievements,
but one of those was based on a magic phrase that may have been the most famous in the
world.

Abrahadabra.

The phrase was well known in the context of mocking those who believed in the occult,
but very few people knew it was more often included in magic charms and magic circles
than in spoken incantations.

Its effects could be described as a curse reversal.

When an enemy cast a curse, such as the Eye of Horus or an ankh, it would divert it or
send it back toward that enemy, so it was widely known as a protective charm.

However, just as all techniques are neither good nor evil, it came down to how the magic
was used.

Think of it like light.

If a light-reflecting mirror was curved, it could focus the light on a single point. Then the
supposedly harmless sunlight could be used to start fires or even spark a wildfire that
covered the entire landscape.

This was the curvature of a curse.

The concept had naturally arisen in all cultures, eastern or western. Someone might have
a doll take their place, or someone might divert an enemy’s aim by escaping inside a magic
circle drawn on the ground.

The curse itself might not be that rare.

There were curses that took undirected resentment or jealousy and used a spell to create
an invisible arrowhead or bullet. Countless numbers of those were traveling all around
the earth like the high speed connections of the internet.

The “human” did not even need to refine his own magic power.

He did not even need to reveal that he could use magic.

He only had to capture one of the invisible curses flying around like a wireless LAN signal,
slightly twist it, and redirect it. Since he was using someone else’s curse, there was not
even the slightest chance of the curse being traced back to him.

Abrahadabra.

That “human” drew out an upside-down triangle with the same letters arranged in a
regular fashion.

That magic circle had been widely known since ancient times, but he had found a new
interpretation and successfully built it into his own magical system.

The true name he had given the curse-reversal circle said the following: I supply lightning
for thy death.

It was a truly ironic phrase for the strongest of the Electromasters.
