She knows legendary magic but ended up a slave? Might be a fetish of hers, I'd say. Could've dodge a bullet there.

Obviously a mini-harem of green shorstacks is a good choice. Both aesthetically and economically. Plus, if they're fast breeders, you can have some warm and wonderful nights while also building yourself an army of the little fuckers to swarm your enemies. Maybe teach them a thing or two about combat so they're aren't just meat shields and you could become unstoppable.

I'd recommend you Re: Zero falls and Konosuba, although they are both very different shows.

One is about a guy who just can't die but get bodied by absolutely everything in the new world repeatedly until he groundhogs his way through. The other is about another average guy who is surrounded by your average retarded D&D party.

Both are well written, Konosuba is hilarious and the two heroes are charming and flawed losers who slowly evolve to become better characters.
