Isekai Nanpa: Mushoku Hikikomori no Ore ga Skill wo Kushi shite Neko Ningen ya Shinuchuu Dragon ni Koe wo Kaketemimashita

A 35-year-old unemployed hikikomori still living in his parents' home, Yuki Yamada was crushed by a mountain of cardboard boxes at his first part-time job and was summoned to another world. The magician Shion asked Yuki to "save this world from destruction with his power," but Yuki, who had a dream of "flirting with girls," used his reincarnation bonus to acquire the "Basic Conversation" skill.
