Masaru is an ordinary middle-aged guy who does construction work on convenience stores and home centers and whatnot.
Do I really need to give you the rest? Reincarnated in a young body, bunch of low-quality skills but are good for his own profession, decides to do construction again, girls with rabbit ears, slow life.
