The laser sword, confined by an electromagnetic field, flashed past, leaving wounds that looked as though they had been melted through by intense heat.
The corpses of slave traders lay piled around the Great Angel.
Using light energy naturally consumed more of Sephiroth's stamina than using lightning directly.
By his estimate, nearly three times as much.
(The conversion efficiency from electrical energy to laser energy was 38%.)
Fortunately, Logia powers consumed little stamina to begin with, so ordinary battles hardly caused any noticeable fatigue.
Putting away his lightsaber like a Jedi, Sephiroth swept the entire slave ship with his Mantra again.
There were no enemies left on deck, and the slave traders inside the ship had mostly caught on. They huddled in the cabins, trying to return fire with muskets.
But against knights clad in adamantine power armor and wielding Electromagnetic Rifles and electrothermal heavy swords, their resistance was practically nonexistent.
As Sephiroth led the advance into the ship, several spheres of light floated beside him, firing laser beams at targets like floating gun turrets.
They were essentially plasma confined by magnetic fields. When the excited electrons reached their highest energy levels, stimulation from the magnetic fields caused them to emit high-energy photons, producing lasers.
Perhaps because they noticed he wore no helmet, the slave traders hiding in the cabins began shooting at his head.
But their bullets bounced away as though they had struck some invisible force field.
Sephiroth mainly went without a helmet to present the Great Angel's public image. There was also his personal hot take that only grunts wore helmets.
Still, to complete the look, he had fitted a decoration resembling an iron halo behind his custom armor. Of course, it was merely decorative and served no practical purpose.
"Damn it-why-why?! Why did we have to
