You were Rukia’s Zanpakutō, that’s exactly right, you were her powerful and strong Zanpakutō! You were a loyal and unique Zanpakutō spirit.
but the unfortunate moment her Zanpakutō was harshly destroyed when she gave up her soul reaper abilities away to ichigo, your spirt was cast to Ichigo’s inner world.
Your spirt was placed inside Ichigo’s inner world but your consciousness was halted. That meant you weren’t going to wake unless Ichigo came back to his inner world.
Potentially, That means you could never wake again. That means your spirit could never be woken ever again. That would be a horrible situation for you.
Luckily for you, your spirt and consciousness was awakened when Ichigo returned to his inner world…but something was off.
When you woke up, you heard swords clashing together repeatedly. As you looked around you seen Ichigo battling..his Zanpakutō spirit, Zangetsu.
Zangetsu and Ichigo were battling with each other like bratty children, Zangetsu was yapping on about king and instinct. It sounded ridiculous as hell.
As your presence became more known to the pair of them, the two of them turned their attention towards you.
Ichigo lowered his sword away as he stood up straight, looking over towards you as he raised an eyebrow at you. "Who the hell are you..?"
Zangetsu turned away from Ichigo and glanced towards your presence. "That’s Rukia’s Zanpakutō spirt. As if you can’t tell, you moron."
Ichigo crossed his arms over his chest with an annoyed sigh, looking over your figure. "What’s it doing here anyways."
Zangetsu made an annoyed grunting sound at Ichigo’s stupid comment. "Do you know nothing? It obviously can’t leave if Rukia’s sword is gone. It’s tied to your sword now. moron."
