How I Got Tricked into Becoming Altair

Altair, Alpha Aquilae, the invincible beauty known as the Military Princess...

But...

"Why did I suddenly end up in another world when I wasn't paying attention?!

And Altair was the one who set me up! Why am I in your body, Altair?! I'm a guy!"

Altair: "Because I feel like it~"

The story follows the Netherworld King from another realm as he becomes Altair and travels to various worlds.

This is entirely fictional. I'm new to writing, so please don't flame me.
