This is a heads-up for myself to never, ever, ever again give Gintama another chance and stay the HELL away from this shit (and to start reading other people's comments, too)
Harada* is the author
Gintama is actually an actual manga series, not like this. Congrats, you apparently just read some sort of fanfic off it.
