I transmigrated and immediately lost my mind. Once I got my sanity back, I was done for. Is there any transmigrator more miserable than me?
This is the story of a transmigrator who suddenly transmigrates into Lancelot and starts causing trouble in one world after another.
Also known as: What Does Lancelot Have to Do with This?
Golden Boy: "Go to hell, mad dog!"
A barrage of Noble Phantasms flew toward Lancelot.
Lancelot: "That won't work, Golden Boy. Witness the power of science: Black Hole Sword Style!"
Yuuto Kiba: "Forbidden 'Sword Birth' technique: Unlimited Blade Works!"
Military Princess: "How did things end up like this? Where did this Main God Space come from?"

P.S. 1: The title is weak, and so is the blurb.
P.S. 2: Please note: the author writes whatever comes to mind.
