[Harem + Mature + Summoning + Diverse Races Harem + Upgrade]Negut has transmigrated, but this time, he never expected that his girlfriend would also come to this world.Not only that, his girlfriend has become one of the most terrifying existences in this post-Apocalypse world, where modern technology is combined with magic.Only having the F-99 rank class, Slime Summoner, the weakest of all classes?What is even more unfortunate is that because he had borne all of his girlfriend’s disabilities in their previous life, in this life, he is a cripple. One leg missing, one eye lost, and his lung function severely impaired.It is fine.
