Yuyou and Hakusho: Sign in at the Beginning of the Game

He accidentally traveled to the world of Yu Yu Hakusho and became Yusuke Urameshi's classmate at the beginning. I originally thought I was traveling through an Academy City. Who would have thought that the novice gift package given to him by the system would be a Zanpakuto Ryuken Wakahu and a Zanken Zuki trained by the Shinigami. From then on, there was a lawless agent of death in the human world. "Yusuke, from now on we can talk about our own affairs. I will call you brother, and you will call me father." "Kuwabara, do you want to defeat Yusuke? Find out more about the Quincy." "Kurama, come and put on this female costume, you will be the brightest kid in this martial arts competition!" "Hiikage, you are actually a descendant of the Uchiha clan. The black flame you use is called Amaterasu, and your move is called Kagu Tsuchimei." "Xian Shui, your personality is called schizophrenia. This is a disease that needs to be cured..." "Little King of Hell, I really don't want to be a detective in the spirit world." "Lei Chan, I'm not interested in this ruler of the demon world. What? There are thousands of beauties from the demon clan? I'll think about it!" The introduction is weak, please read the main text. The main text is weak. If you can't do it, then you can't do it. Anyway, this is a nonsense story. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
