Soubi Seisaku Kei Cheat de Isekai wo Jiyuu ni Ikite Ikimasu

29-year-old Toji, a job-hopping part-time worker, got caught up in someone else getting summoned to another world. Declared a troublemaker on arrival and thrown out of the castle, he was just about to lose all hope when a status screen from an online game he used to play popped up in front of his eyes. Amazingly, Toji can use that incredibly convenient game mechanic in this new world, and he's the only one! Upgrading weapons, summoning adorable monsters... Armed with all the knowledge and wit he can muster, Toji is free to venture wherever he pleases! (Source: Alpha Manga)
