[Comprehensive] When Sawada Tsunayoshi Became the Black King

Sawada Tsunayoshi felt that his life was an out-and-out tragedy: before the age of six, he was an out-and-out "waste". He failed in exams and sports, and was often bullied by his classmates. He was called "waste Tsuna". But at the age of six, he inexplicably became the Black King, the sixth king with attributes that did not match his at all. From then on, his life became abnormal: he sensed other people's emotions without any preconditions, had a detective friend who killed people wherever he went, and even encountered creatures called vampires when he went out for a walk... He finally managed to seal the Black King's power at the age of fourteen. Just when Sawada Tsunayoshi thought he could finally live a normal life, a little baby with a yellow pacifier came to his home to train Sawada Tsunayoshi into a competent Boss. Conception:
