Kousuke here: brood over his weapons killing people
Kousuke later:
"Some high ranking person tried to test out whether I'm suitable for the dragon waifu, I should drop the fucking nuke on this country"
Isla/Aira + dragon waifu "Ok that's too much"
Other things he also have:
Giant golem with gatling guns, as well as smaller golem (but it's still like 3m tall iirc) with magic rifle.
Flying ship (the cost of which is beyond any single country's budget because he use mithril and such as if it's common metals as well as basically magical nuclear engine)
The magical nuke mentioned above (the affected area become so saturated/radiated with magic that no plants grow)
He still would prefers not to resort to killing/violence
But he's long accepted that between the lives of people he care about vs others, dakka.
