Holy shit I forgot that when Usagi erased Minako’s memory, she erased Artemis from her mind, too.
He stays with Luna and Minako doesn’t remember what the fuck WHAT THE FUCK
“Minako and the other Guardians are finally leading peaceful lives. I don’t want to spoil all of that for them by bringing them back.”
For fuck’s sake, Artemis would rather live a life where Minako doesn’t remember him because she’s finally normal (what he knows she always wanted) than bring back her memories of him and make her fight I AM A MESS.
