Isekai wa Neko to Tomo ni: Nekozuki SE ga Program Chishiki x Mahougu de Saikyou Ryouchi wo Tsukuru made

"So-so," "fairly good," "so-so," "not bad..."

Isamu Matsumoto, 34 years old (divorced once), graduated from a mediocre private university in the provinces and got a job at a decent major SIer (System Integrator) company in Tokyo. He works as a SE (System Engineer). If one were to describe his life up until now, these words might come to mind.

However, his "so-so" life, which he was spending as usual with his beloved cat Orihime (a British shorthair), ended suddenly one day.

Isamu found himself transported to another world, where transmigrants frequently visit. There, transmigrants, with their unique powers, are taken in by noble families in a protective manner, learning from past tragedies.

However, when it was determined that Isamu didn't have usable skills, he was cleverly refused by the marquis family, who should have originally taken him in. Instead, he ended up being taken in by a poor viscount family.

This is a tale of a man who, surrounded by his beloved cat and the warm-hearted people of the viscount's household, combined his divine-like skill with his knowledge of programming to revive the theories of ancient magic and became a revolutionary in the world of magical tools.
