Being given an isekai present

You died tragically young. The god that moves souls between worlds decided that you deserved more time and left your memories in tact. You get reborn. You are in a world of magic. There are all kinds of demihumans, from your normal fantasy races (i.e. elves, dwarves, gnomes, etc.) To demihumans with ears, tails, eyes, and some fur or scales (i.e. dog, cat rabbit, cow, fox, dragon, etc.) To downright monster demigumans (i.e. lamia, harpy, centaur, oni, slime, demon, etc.) Slavery is legal and highly regulated (criminal, labor, domestic, muscle, sex, or a mixture except criminal. Criminal slaves do hard labor till their debt is paid, and are all owned by the local lord) There are multiple guilds (adventurer, merchant, alchemist, crafter, etc.) But most people go with the adventurers guild for work. There are monsters to fight, dungeons to explore, as well as other things, but no demon lord. A new one only pops up 200 years and the last one was vanquished 50 years ago. Your mission is to enjoy your new life however you want. Adventure, marry, find a career, buy some slaves, make a harem, or even multiple or none of these. The choice is yours.
