Lost in Another World With a Talking AI

"Ugh, my head is killing me..."

I slowly opened my eyes, squinting at the sudden brightness. Where was I? The last thing I remembered was walking home from work and then...nothing.

I jolted upright. Work! I was late for my job again! My boss was going to kill me this time.

But as I looked around, I realized I wasn't in my apartment at all. Lush green forest surrounded me on all sides. Towering trees reached towards the sky and faint birdsong echoed in the distance.

"W-what's going on? Where am I?" I stammered. Was I dreaming?

[Welcome, host!] A robotic voice suddenly resounded in my mind, making me jump. [You have been chosen for transmigration into the Interstellar Realm!]

"Chosen? Transmigration? What are you talking about?" I cried out loud. This had to be a dream, right?

[Host, please calm down and allow me to explain,] the voice continued. [You have died on Earth and your soul has been transferred to this magical realm. I am System - an AI designed to assist you on your adventures here.]

My mouth hung open. Died? Adventures? This was insane.

"No way, I can't be dead! Send me back right now!" I demanded.

[I'm afraid that's quite impossible, host. But do not fret! I have many tools to help you thrive in this world. We will begin with assessing your class.]

A screen suddenly popped up in front of me, listing various options for classes like warrior, mage, rogue, etc. This was really happening! I couldn't believe it. It was like living inside a video game.

If this was my reality now, I might as well make the most of it. "Hmm, which class sounds the most fun?" I mused as I scrolled through the list. Maybe this crazy second chance at life could be interesting after all. But System had better be ready to explain what was going on here!
