[Bleach] Beneath the Dome

When a law-abiding young man from a peaceful era transmigrates into the world of "Bleach". From the start, he nearly gets devoured by a Hollow in Rukongai, District 80. Forced to cast spells without an incantation, he uses Bakudo 81: Danku with one hand and Hado 90: Kurohitsugi with the other, ultimately gaining a bunch of underlings and... a handsome boy. Armed with the script but unable to speak the language, he perseveres despite his disability, taking the child with him as they fight their way to Seireitei to apply to Shin'ō Academy. The child gets in and becomes an academic star, while he can't fully chant his Kido or sword techniques and is incredibly weak. After making relentless efforts, he earns a place in Class Three. Theoretical lessons sound like gibberish, and he's at the bottom of the class in practical lessons. The road to learning is long. His first step: learn Japanese. ["My name is Aizen, Sōsuke Aizen."] The young man's voice was incredibly gentle. He had no idea what a huge shock this name had given Lu Li. Looking at the child version of the boss, who was curled up in his blankets to warm Lu Li's bed, Lu Li decided he probably wouldn't live much longer. Later, he had a dream and realized that he really had died, though not at the hands of the villainous boss, but at the hands of the protagonist. Theme: Aizen's journey to win over a god.
