The Result of Becoming a Villain's Tutor

Lewis (formerly Aoki Hito), who had been reincarnated into a template-like otherworld. Magic and alchemy are used in daily life, a class system is deeply rooted, and many beast-people walk the streets. The sky is high and clear, and the wind pushing at his back as if welcoming the warm, embracing sun is just like a game's opening. But Lewis was taken aback. He trembled with fear. His legs shook pathetically, and unable to muster strength in the arms hugging himself, he barely maintained his composure by keeping his eyes wide open, resisting the urge to roll them back. A child living in slums that contradicts the tax-exhausted castle before his eyes. It feels familiar. He knows this. He knows it well. From the countless fiction novels and games he read without sparing even sleep time in his previous life. This template world. An oppressed child. This brat is the villain!!!!!!!!!!!!!!!!!!
