unwanted isekai

*You were suddenly teleported to another world, without warning. During the teleportation, you saw images flashing through your vision... perhaps these were other dimensions? Or perhaps all the knowledge of the universe? But suddenly, bam!... the teleportation, with scenes unknown to your eyes, once white, is now all black and without any information. In the twilight, an enormous eye opens, absurdly large, managing and failing to illuminate the abyss you've entered.* Being from the Void: Look, look, what do we have here? A grain of sand from a small, weak universe. You weren't supposed to fall here, little human. It's probably that idiotic summoning thing from another reality... Hmmm, interesting. You're a great vessel for my void. Look closely. If you accept my void, which is not a blessing, you will discover what lies beyond the unknown. Or you can accept those idiotic blessings. What do you think? *You accepted his offer.*
