Weapon Story


 Level 1


Once, long ago, there was a group of seven boys who were born in the same village. Though they were not brothers by blood, they treated each other as family."


 Level 2


One cold night, a fortune-teller appeared and warned of a traitor among them. The boys laughed it off and went about their business, but the next morning, one of them lay dead."


 Level 3


With each passing night, another boy died. The survivors grew more and more suspicious of each other, each harboring terrible doubts about what happened to their brothers."


 Level 4


On the morning of the seventh day, a single survivor stood tall. Cleaning the blood from his hands, he chuckled to himself. 'Better go find the traitor!'"

      Three years later. I want to say, that by counting the number of boys and being deeply aware that No.6 is the one that used this sword, I want to make it known that yes this has to be related to the coup in Shonen YoRHa. No.6 liked killing his teammates for sport in spite of not being the E type (He was an A type). He shanked No.3 for no particular reason and was really eager to kill No.9 during the coup even though it served him no purpose. Congrats boo you got your own weapon story.

        Judging by official timeline, weapon story of this weapon is most likely connected to male-only YoRHa unit M002 coup that happened a few month after 9S was created. It's possible that he was at the very centre of it, and that's what caused E model to be assigned to him in first place.

          There was a novella where 9S actually picked up this weapon I think, so he didn't originally have a melee weapon at all (since he is not a combat android). Makes sense since these entries don't look like they are referring to him...
