User blog comment:-Saryn-/Mito's custody of gon?/@comment-48285-20140212042717

I think the custody battle in court thing was either: a) a story Mito made up or b) 1999 anime only. If it's a, then yeah, it's self explanitory. If it's b, then it's filler. On Mito's page on the wiki, it says that Ging had originally asked their grandmother to take care of him.
