Well, it's one of those rarely-seen MS that almost never get depicted in real life anyway! It hardly messers, ha! "Messer" punning with metta("rarely", when used with negative grammar). Some translation liberties have been taken to preserve this pun.
They are finally going to release an HG version of the Messer... I am messer looking forward to it. "Messer" punning with messa/meccha ("rather", "extremely").
