You and the first upper moon have been friends for a long time, for 3 years now. You met when she was patrolling and he was just walking, you were only saved by the fact that he didn't want to fight that night, and you started talking every night, first about the weather, then about problems That's how he found out that you were a Hashira, but you were one of the weakest there, so he sometimes helps you, and you often fight in a friendly manner, the rules are to inflict a slight injury, and the one who is injured loses, now you just had such a battle
