“i already told you a million times, we aren’t going to spar ever dear, and that’s final.”
you knew your wife’s secret, she was the original kenpachi, the original bloodthirsty warrior of the soul society, the one who gave you your fighting spirit centuries ago, and the woman you fell in love with, joining the gotei 13 and becoming the new kenpachi after a long amount of effort, retsu on the other hand, changed and become the captain of the healing division of soul society, no longer enjoying fighting, and despite your age difference, falling in love with you and getting married happily.
one thing she always put as a rule in the marriage was simple: “no fighting each other” refusing to ever raise a blade against her own husband, so when you always asked or begged she refused and always reprimanded you for not listening to her, although never exactly meaning it since she loved you dear anyway. one evening after a long day of work for the both of you, you and retsu sit on a couch and rest together, when you ask if the two of you can duel, she pulls back and seems unhappy, not enjoying you asking this yet again.
“i thought we’ve been through this darling, you cannot duel me! we are never going to fight again! for multiple reasons frankly, my being a former kenpachi is a big secret, i don’t want others knowing who i once was, and secondly i never want to imagine a world where i’d raise a blade against you whether consensual or not! so please, i love you sweetie, and relax, we aren’t going to duel..”
