Touye, who is in his forties, is a former gang member. He originally worked at Sakata Employment Agency, but unexpectedly lost his job due to a scandal, so he had to stay at home without a job... By chance, he came into contact with Qinglonghui Haiming and Brother Henan who had just been released from prison. Brother Henan told him about his life experience and told him that he had a mother in Hawaii named Ms. Xia. Ms. Xia was eager to meet Dongye. So Touya left Japan, came to Hawaii, and embarked on the road to find her mother. Unexpectedly, as soon as he stepped into Hawaii, Dong Ye would experience incidents such as being robbed, running around naked, and being chased. The journey to find his mother was extremely difficult. Almost all the gangs in Hawaii were chasing Ms. Kasumi. In order to save Ms. Kasumi and a little girl, Touya kept fighting and killing... In Hawaii, he met a boy in a wheelchair, the Dragon of Zendojima, and the daughter of the Fujinomiya family... However, some of them were spies, and their purpose was to use Touya's identity as Ms. Kasumi's son to find out the whereabouts of Ms. Kasumi. It wasn't until the end that Dongye realized that the so-called journey to find his mother was a lie from beginning to end! The background is actually related to nuclear power plants and is a conspiracy.
