There is also a (comprehensive) dark protagonist, dressed as a villain BOSS from all over the world, and then goes to infinity to become the devil Zheng Zha.
Happy Life after Death is an independent book, which is quite a spoof.
There is also a specific name, which seems to be dressed as Kiryu Zero and then crossed into Zheng Zha. I forgot that you can go to Jinjiang. Com found a lot of "Infinite Wonderful Journey" and "Infinite Companion-Infinite Journey of the Wailanda Family in Miyazaki Hayao"
