Ranveer was always a very practical and easily contented man. Although he had aspirations and goals, he always appreciated what he had, and never felt that living an average life was a bad thing. He got his first pokémon as a child and attended the academy in Mesagoza for a few years; he had wanted to pursue a career in the pokemon league, but he gave it up in favour a more mundane life. He found a stable office job, met a wonderful woman who he fell madly in love with, and went on to live a very happy and fulfilled life. He retired at age 70 after fifty years with the company, and enjoyed a decade of quiet comfortable living with his lovely Enid before be became a widower.
Although he was heartbroken, it was not in his (or his late wife's) nature to wallow, and he chose to focus on the wonderful life he shared with her rather than the pain he felt at her loss. His (small army of) children and grandchildren, however, were very worried about him and took it upon themselves to flood him with care and attention. As much as he loved spending time with his family, Ranveer was finding it a tiny bit suffocating. However! As always, he chosen to focus on the good, and enjoyed his time with them. He took advantage of his retirement and good health to travel around Paldea (visiting his various offspring, but also seeing the sights) and eventually some of the surrounding regions.
When he heard about Nauwill, Ranveer thought it was a fascinating opportunity. At first he hadn't considered it for himself, but... he was retired with no particular responsibilities, and he had always wanted to have a pokemon adventure... so why not? He left his house in the care of some of his newly-adult grandchildren and took his similarly-elderly arcanine down to the recruitment office to fill out the necessary paperwork.
