My Everyday Life in Another World (Tentative)

I am a person with memories of being Japanese, and 15 years have passed since I was born in this different world. Born as a commoner, I have not used my Japanese knowledge to create a harem, nor have I been overpowered with cheat abilities. I have lived a peaceful life. However, that peace crumbles when I enter the academy. Surrounded by a selfish princess, a girl swordsman known as the academy's strongest, a girl genius mage, and the daughter of a great merchant, I get caught up in trouble. Where has my peaceful daily life gone? A post-school life story in another world and an academy. There will be no adventures. There is no purpose. It's a laid-back story using knowledge from Earth (food, toys, manga, novels). (Posting is extremely irregular, depending on my other works)
