Reincarnated In Underworld

I did get a suggestion on being a harem which I am not doing since it will probably give me a headache. Also, there is another thing I want to know is Kraven is a power-hungry but predictable guy so do I have Lucian fake his death since he does have a child after all and that would make Kraven the reagent also It will make it easier for me to write the whole thing.
