Manhiro Tsushima is the head of the most powerful and respected Yakuza clan in Japan, but before becoming the head, Manhiro had to go through difficulties. 

At the age of 23, Manhiro shouldered the impossible burden of caring for a sick mother, who at that time was already at an advanced age, but still tried to provide her son with everything necessary. The son, seeing this, scolded himself for his helplessness, tried in every possible way to find a way and means to treat his mother and further care for her. At one point, he heard that the Scarlet Sakura Yakuza clan was recruiting volunteers. Manhiro had completed military training, trained hard, and was strong in body and spirit, so he was confident that he would be accepted. Upon entering the clan building, he was stunned by how luxurious it looked from the inside. Near the stairs to the second floor stood a tall, dark-skinned man in his thirties, who motioned for Manhiro to come to him. 

- Have you come to join us as a volunteer? The man asked. 

- Yes, that's right. Manhiro replied, gazing intently and with some kind of threat into the eyes of his interlocutor. 

"Are you strong enough?" After asking this, the man aimed his fist at Manhiro's face.
