Dokja will obtain the title of Demon King of Salvation in the 3rd floor because of that he will be the boss of the 3rd floor, in order for them(dokja companion's) to proceed the next scenario they need to kill dokja.
There's also a revelation/fate that dokja will die at the hand that he love the most (there is funny part there because they use some kind of item to identify who dokja love the most).

So who does he love most <3
