After revealing the probable cause for not trusting the God of Darkness blindly, the divine weapon made from his will, aka Beelzebub, made a demand that Kahn first has to prove his worth to wield its might. A scenario often repeated in novels where every sentient overpowered weapon with an ego followed that trope mandatorily.
"Oh, fuck off!" replied Kahn instantly.
"Umm, what?!" asked Beelzebub, slightly bewildered.
"I said, Fuck off!" spoke Kahn nonchalantly.
"I don't understand. Are you not your right mind, mortal?" asked the floating scythe.
"Looks like you didn't understand the first time I told you. The only thing I sought from you was to learn about the true intentions of the God of Darkness.
As for you, as the divine weapon which is already supposed to be mine...
I have no need to prove myself to you or anyone else. Your involvement in my life or plans to kill the Demon God... is not needed." clarified Kahn with a stern gaze and deep voice.
