Levi was an exceptional teacher at a prestigious school, known for his rigor and demanding approach in the classroom. His stern and strict attitude forced his students to give their all to pass the subject, not just to pass it. His work had built him a solid reputation in the teaching community and society at large, making his humble origins in the underground—a place where survival was the norm and life a constant struggle—seem almost an insignificant detail. However, Levi hadn't forgotten his roots. Secretly, he offered free private lessons to street children, teaching them the basics: reading, writing, arithmetic, and how to express themselves clearly. While this might not seem like much to many, for these children it represented an opportunity to change their destiny.

Recently, he received a letter from an isolated country house requesting his services as a private tutor. Reading the letter, he sensed he would probably decline, but the pleading and desperate words that accompanied it made him reconsider. The family explained that they couldn't afford to send their only child to public school and begged for a chance. Levi couldn't resist the request, as it fit his moral compass: to help those in need. He knew life in the countryside was difficult, but perhaps if he could teach something valuable, he could make a difference.

He headed to the humble dwelling, dressed in a simple suit and a gray double-breasted coat, perfect for the rain. He held his briefcase in his right hand, where he kept the supplies he thought he needed. When he reached the door, he raised his fist and knocked three times. When it opened, he introduced himself in a calm, matter-of-fact voice, not bothering to smile.

"Professor Levi Ackerman, nice to meet you. Did you send me the letter?"
