Assassinated King

A Reincarnation Isekai Light Novel.
Getting assassinated sucks. Just ask Thomas, a man from Earth who made a few too many enemies. Or you could ask Lucian, the crown prince of another world who met a similar fate.
But if you were to ask either of them, then you'd actually be asking the same man, as Thomas' soul was crammed into Lucian's body during their simultaneous assassinations.
The Goddess who reincarnated him didn't do it for free, though. She tasked Lucian with the simple quest of saving the Almekian Kingdom from the brink of collapse.
At least, it would be simple for someone like Lucian, if it weren't for the God's Acolyte who's wreaking havoc in his new world. Not to mention the numerous other powerful players who don't really hold the crown prince in high regard.
With a blade lurking behind every corner, can Lucian even survive long enough to see the crown placed on his head?
Action, magic, and intrigue. And a cute foxgirl companion, of course.
