these two are the last to leave Queen Serenity's side after the battle on the moon. she asks them to watch over her daughter and the rest of the scouts.

Artimas is the first to take action he finds Sailor Venus who is origenlly known as Sailor V (side note the Sailor V mangas were writen before the Sailor Moon mangas causeing her to make the Sailor Moon spin off). the two of them continue to do thing and get in the public eye in order to find the rest of the scouts. their plan succeds when the scouts read about her in the paper and she comes to there aide. artimas is also responsable for making Sailor V the decoy princess, this was done to prevent the negaverse from going after Usagi

Luna arrives on earth and is cought by a group of kids who are kind of mean to her and also put a bandae over her moon thus making it so she could not communicate nor find Sailor Moon. this is how Usagi finds her she takes it off the cat and it jumps away and not sure if she found the right girl or not wandders away only to show up after Usagi gets out of school to tell her of her hiden role as Sailor Moon. Lunas memroy of Usagi being the real princess was erased so she could not tell usagi untill it was needed to be known

all the sailors pets/gardians are from there own respective planets these two come from the same planet (sorry i dont know if there is a name but i will look) as Sailor Tin Nayoko (from the sailor stars season)
