Ging initially tended to leave Gon under the care of his Grandmother, but Mito deemed Ging unworthy of raising a child, so she filed a case against him and took complete custody of Gon. A decade into the Hunter business, Ging returned with a two-year-old Gon following his separation from his wife. With all that was going on in his life, he couldn't raise a child alone, so he came to seek help from his Grandmother. Another reason was that Ging knew he wouldn't be a good father. Well, it all turned out for the best. After many years, gon finally reunited with his father, and we got one hell of a story to experience.
