Protagonist travels between different anime worlds to right wrongs and uncover his reason for being along the way.

“I don’t care about how people in this world live, whether they have enough to eat, whether they can wear warm clothes, whether they have dreams and hope. I don’t care about their likes and dislikes.”

“It’s just that if you want to go to the sky, you need a complete advanced industrial system, a set of related research institutes, the most advanced materials science laboratory, and a big government that can coordinate all departments. It needs countless people who don’t have to worry about food and clothing. Dedicating wealth for this requires millions of high-level intellectuals to contribute their minds, and tens of thousands of different supporting manufacturers supply the best parts.”

“In short, it takes a world of abundance, and a great civilization to accomplish it.”
