Good news: I transmigrated. Even better news: I became Absolut Tarunas, the younger brother of the Golden King, Tartarus.
With his big brother leading the Kingdom, Tarunas naturally lived a life of comfort and luxury. He was one of the Kingdom's most prominent figures, too.
He had been living peacefully in the Kingdom when, one day, his good-for-nothing big brother Tartarus suddenly came looking for him:
"Tarunas, if the Kingdom ever faced the threat of annihilation, would you put yourself on the line for it?!"
"Absolutely! The Kingdom is our home, and protecting it is everyone's responsibility!"
"Good! You're truly your big brother Absolut Tartarus's brother. Then I'll entrust you with the arduous task of infiltrating the Land of Light!"
"Huh?"
Tarunas had only been making polite conversation. He stared blankly at his completely serious big brother, but before he could explain himself, the Golden King sent him away through a little Golden Gate.
When he opened his eyes again, a huge green-glowing planet loomed before him. His big brother's solemn voice rang in his ears:
"Tarunas, my foolish little brother! I'm counting on you to infiltrate the Land of Light! Once you're in place, we'll work together from within and without, and we can definitely conquer it!"
Fine, you want me to infiltrate the place. Fine, you forcibly teleported me there. But what era of the Land of Light have you sent me to?
What do you mean, the big-horned guy is still only medium-horned?
Belial is still White Belial right now?
