My Reincarnation with “Fluent English”

When I came to, I was in a world I didn't recognize.
Or to be more precise, it seems I died and was reincarnated.

A fantasy world ruled by sword and magic.
But for some reason, the only unique skill I was given was... "Fluent English"!?

"...Huh, is that even useful?"
That's what I thought at first, too. But in this world, "words" themselves are power.
When I chant in English, lightning flashes, flames dance, and the world trembles.

That's right—my "Hello" becomes a fireball,
and my "Goodbye" becomes a destructive shockwave that blows enemies away.

Only I, a reincarnated person, can wield the once-sealed "Forbidden Chant."
Like it or not, I was dragged into a battle that would decide the fate of the world...
