After settling in Edo on Earth from Royo, you played an otome game.
It is said to be a masterpiece set in Edo, a future 150 years in the future (without Celestial Beings), and filled with various super high school-level genius characters.
Here, you can conquer the scientific boy who started making rockets at the age of eight, the rich second-generation young man with a pocket money of hundreds of millions, the eloquent and mysterious magician of the mind. If you find these boring... You can even travel across the ocean to another country to conquer NASA's genius scientist, and the dangerous and charming special forces captain.
In this regard, only children make choices, of course you as an adult want them all!
You played the game with great interest, maxed out every line's favorability points, reached HE and obtained their confession CG.
Then you uninstall the game and play something else.
One day, your unlucky neighbor accidentally broke Master Gengai's new invention. Unfortunately, you next to him were involved in it. When you opened your eyes again, you found that you had traveled through time.
You traveled back to the game you once uninstalled, PS: 3700 years later.
After humans were petrified for 3,700 years, they woke up again from petrification and finally found their long-lost girlfriend who had been inexplicably missing.
But your "girlfriend" and my "girlfriend" seem to be the same.
In this regard:
You: ... Retreat from the Shura field, retreat! What's wrong with the Queen hugging you from left to right?
But - how did the promised otome game turn into the revival of civilization?
If you do this, you, the great inventor of Edo, will not be sleepy.
……
What? You said I wasn't that good at fighting before? Nonsense, how can a mere otome game load the universe's strongest Yatsura bloodline?
What? You ask me how we created a time machine and a spaceship that can go to any planet? Isn't that simple? Don't underestimate the name of Oedo's first inventor (self-proclaimed)!
What? You say this is unscientific? Then ask Sorachi the orangutan:) Besides, you are obviously very unscientific, okay?
Stone Age + Gintama
The heroine is a night rabbit who has traveled to the Stone Age. She is a god with full martial arts and Gintama-style science fiction inventions.
It's a silly otome novel, and I can't write about any hard-core science. The question is about science fiction, jokes, and whether you want to compete with the funny ones!
