Proposal details

This proposal will make the following change(s):

Update the name of the manga Uchuujin no Kakushigoto

Change the name from Boku to Uchuujin to Uchuujin no Kakushigoto

Based on the following reason: incorrect name, when making this manga I accidentally put wrong name and it is easier to just change the name
