Republican Era: I Awakened a Pocket Dimension to Save My Life

A modern-day couch potato lands in the Republican era with nothing but the clothes on his back. He has a pocket dimension, guns and cannons, and cheat-like advantages. The Japanese end up running around naked. Is this the start of wild escapades, or a round of love-making? No! It's selfish desire at work! It's unrestrained lust! It's the many faces of the world. No! That's not it! It's a revolution of the self! It's the elevation of love! It's the warmth and coldness of human relationships. No! Not yet! It's freedom of the soul! It's the cultivation of the human body! It's finding one's true self. Everyone, be patient and read on. Is that chuunibyou version of yourself the one who lost their soul? Does that dream from your youth still echo in the dead of night? Every story ends with regrets! Every broken thing will one day be made whole!
