MTL - The Best Male Supporting Character In the Pet Text is Reborn - ~ Work related

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?

“Aurora White, from now on, you’re not my fiancée anymore and you’re banished from the kingdom!”Taking out the fan to cover her mocking smile, Aurora watched the crown prince spouted the declaration from the stage on their graduation ceremony and sneered.Banished?So, the time has come?The corner of her lips curled up slightly.For her or for the kingdom?Because in Aurora’s eyes, she can only see a bright path for her future....Story set in settings similar to middle ages...

On a normal evening, a voice appeared out of no where to give an announcement all over the world, this same evening was also when Dustin was run over by a car while running way from thugs.

Dustin however woke up unharmed, and learned that the world was about to go into ruins basically, and that some humans would be taken away in a few days as 'earth's warriors'.

As it would turn out, on the D-day, Dustin is one of those that were taken. But, this might turn out to be an opportunity rather than a curse, as some night before this day, something interesting happened.
