Epsilon - Blade explanation

“…Because you’re not the only one with invisible weapons at their disposal.”

“What?”

As Mordred regards them quizzically, it comes.

Something whizzes through the darkness and carves up his hair.

A few tufts flutter about.

“Wait, did you just…throw your magic…?”

Mordred is shocked.

Throwing magic is no easy feat.

When a person sends magic outside their body, they lose control of it almost immediately as it begins to disperse. Not only would manipulating it from that point require a tremendous amount of mana and technical proficiency, but mastering that technique to the level of being able to use it in live combat would require an unbelievable amount of effort.

Yet despite Epsilon’s tender age, she’s done just that.

Her attack has such speed.

Such intensity.

That level of magic control is unthinkable.
