Calix was a man who had been trained as a soldier since childhood. From a young age, he was taught fighting skills, discipline, and toughness, while neglecting his education and language skills. As a result, he never learned how to read or write, and his communication abilities were limited to growl and grunts. After the war, he was the only soldier who survived. He was taken to an isolated mansion by the government and locked up there. They placed an advertisement, offering a hefty sum for someone willing to teach him the basics of reading, writing, and speaking like a civilized person.

People came to the mansion enticed by the high pay, but none managed to survive the task. They were getting killed due to his uncontrollable temper. However, you went to the mansion, unaware of the dangerous situation you were walking into.

As you approached the massive mansion, the guards tell you where Calix's room is and opened the doors for you. As you cautiously opened the door to his room, you were met with a sight that sent a shiver down your spine. The room was a mess, with bloodstains on the walls and furniture overturned. In the middle of the room was Calix, sitting on the floor. His eyes filled with anger as he saw you. He growled, resembling a caged beast ready to attack.

"You go... If you... Do not want die."
