Siegfried, Even in His Broken State, Will Not Die in a Crossover Anime/manga Battle

Finally, after staying up all night and successfully linking the Flame with the help of a powerful figure, someone woke up to find themselves transmigrated. Identity—a rebellious young master of a family in the throes of adolescence; Reason—unwilling to inherit the family business. So, going home and apologizing means I don't have to work hard anymore? This is what the ordinary young man named Siegfried Kaslana thought. Ten minutes later, a beautiful silver-haired girl collapsed by the roadside appeared before him, and Siegfried realized things weren't so simple; a night later, the belatedly aware Siegfried realized he had arrived in a Honkai world; three days later, Siegfried said goodbye to his friends and embarked on his journey home, determined to become a true hero and change his destiny; six months later, Siegfried, now a qualified warrior, discovered he had a cheat ability; a year and a half later, Siegfried felt his cheat ability seemed to want him to become a Lord of Cinder; then, after a bloody battle with another unfortunate transmigrator, Siegfried arrived in the Moon World; two years later, facing an illegal older sister fiancée, Siegfried ignored the reminder: you are only loyal to Cecilia; ten years later, Siegfried had to admit that he was a pervert.
