Character-wise, I'm looking at an eccentric, maybe a little paranoid, but quite cocky and witty 'magical engineer'. Basically he incorporates magic into equipment and machineries, or the other way around, creating all sorts of weird but practical stuffs like magic sensors or magic-powered automations. Power-wise, he's nowhere near the magic power of the strongest witch/wizard/magician of the world, but his pragmatism can bridge that gap. I'm considering between him being a native or a computer-programmer isekaied, but just throwing it out there for now.
