We (see what I did there) might be taking Harada a little too serious here with the "Don't ask me for shit" heh. Some of it is also his team in terms of decision making. I heard there's some guy in his team that base things off character usage and statistics for which characters can return, unsure if that's true or not.
But on point, we have to remember that Harada isn't what people make it out to be, he's a social media enjoyer and that the Twitter user who wanted to hit him with a burning hammer took him seriously. If anything, maybe the user wasn't serious either because Burning Hammer is the name of a move in Tekken by King/Jaycee/Julia. You can also ask Gill Hustle for validity on this since he got a picture with him for DOA6 event but fun bit, Harada played DOA6 with him and he enjoyed it. He also physically purchased a copy off of Shimbori's hands at EVO that time. Did he buy it to "steal" ideas? or was it because he also supports other 3D fighters? damn, no one will know. It'll forever be a mystery.
Hey here's another one, he wanted to create a 3D fighter only venue to compete with Ono's 2D fighter venue idea and was willing to put money out of his own pocket for a pot bonus for DOA. Unfortunately this did not happen because Ono left Capcom prior to it, but damn... guess he really doesn't like DOA. Shame.
