The first episode went the self-aware route with all these references to "if you're teleporting me to another world I should've read a light novel first" and "this is a generic fantasy setting" and the last line about letting him erase his hard drive first before being teleported ala reincarnated as a slime
If anything having a yakuza looking guy as the MC is already a plus for me, although I'd point out that the bit about having admin privileges feels like it was pulled from SAO and Aku looks like a knockoff ram/rem from re zero, though that's not exactly a bad thing
