Koga Kuchiki

After an intensive conversation, the Zanpakuto Spirit and their host finally settle with each other, helping each other to become strong.

Each one of Zanpakuto\s Spirit asks a certain thing from another host, the thing they ask is not really hard from Xin's perspective.

It's so easy to do, and nothing will change if they do it in the way that their partner wants them to do.

Sode no Shirayuki for example wants her host to learn to be a proper lady, her unique attitude makes Sode no Shirayuki angry.

The thing is that both of them disagree with each other. Of course, Xin can easily understand that Rukia can easily learn those simple things because she comes from a poor place.

Meanwhile, Momo and Tobiume only agree to talk to each other while preventing each other from telling a lie, Tobiume also wants Momo to be proactive and brave, even though she is also a shy type.

Suzumebachi wants Soi Fon to use her Bakai Form once every month, she also wants Soi Fon to change her barbaric nature.

Haineko and to have time with Xin, and she doesn't want Rangiku with her while she is staying with Xin.

Of course, Ranjiku did not accept her selfishness, she only accepted it if she was around with them.

While the other is just a minor change to their partners.

"So your simple complaints end? Now let's talk about Muramasa, what do you think he wants to do by summoning all of you from your host?" Unohana asks.

"I can feel anger and hatred from that man, when he calls me, I can feel hollow energy from him," Minazuki said.

"Hollow energy? Then is he an Arrancar? Or maybe an Espada?"

"I also felt hollow energy from him. It's cold and dangerous. I feel that he is going to drag me to the darkness if I don't accept his call."

The other Zanpakuto nodded too.

"That man eats something to gain that power," The Cat said.

Xin nodded too.

"Y-You mean he eats Hollow to gain power?"

"To make up for the lack of his Shinigami master, Muramasa is forced to rely on absorbing Hollows in order to remain materialized in the real world. When he absorbs a Hollow, a portion of Muramasa's strength proportionate to the Hollow's power is restored for a considerable amount of time." Xin suddenly said.

"T-That means, he is actually materializing without his own owner?"

"What's the problem with that," Byakko said." Even myself can do that easily,"

Xin looked at Yachiru and said to them," Zanpakuto Spirit can materialize using 2 options, one is that the Zampakuto's Spirit is powerful enough to materialize on its own."

"Just like me." Byakko proudly said.

"The second is to gain unparalleled intelligent and enough Reiatsu,"

"But Muramasa is different, he chose something dangerous, and that is Hollow energy. By doing this he can extend his time in the world."

"We now know what's different to that Spirit, what confuses me, what is doing this? What is his motive?" Unohana asks.

"What do you think is missing to Muramasa?"

"His partner." All of them said then they realized what he wanted.

"You mean he wants to find his owner?"

Xin nodded.

"But who is his owner? And why did his owner leave him behind?"

Unohana suddenly remembers something," I think I remember where I saw Muramasa."

"Me too," Minazuki said.

"Where?"

"Several hundred years ago, a man with the name Kōga was welcomed into the Kuchiki Clan as the son-in-law of Ginrei Kuchiki, and soon gained much respect throughout Soul Society. He, in his capacity as the 3rd Seat of the 6th Division, participated in a battle between the loyalist and rebel factions of Soul Society, winning a decisive victory for the loyalist side by himself."

"Ginrei Kuchiki at that time was the captain of the 6th Division and the 27th Head of the Kuchiki Clan until being succeeded by Byakuya in both positions."

"For his performance, Kōga was given much praise and many accolades from Captain-Commander Genryūsai Shigekuni Yamamoto himself."

"When it became clear that Kōga might very well be the key to winning the war, three elites from a rival faction, who feared Kōga would take the glory away from them, came up with a plan to frame him as a traitor."

"They achieved this by having their own men attack Kōga, whom they knew would easily dispatch them, and then charging Kōga with murder and having him arrested."

"While Kōga tried to explain his side of the story, the Keigun ignored it and moved in to make the arrest, which led him attempting to retaliate. Ginrei immediately persuaded him to stand down for the moment and go quietly, which Kōga did reluctantly."

"Ginrei visited Kōga in jail, and detailed that his punishment had been handed down: Kōga was to be suspended from his seat in the 6th Division, and Muramasa would be neutralized because its powers were too dangerous."

"That night, Kōga killed the elites who framed him. Upon hearing of this, Ginrei went in search of Kōga, and found him in the outskirts of Soul Society. When Ginrei confronted him about his actions, Kōga explained how he had hoped that deep down, the officials would regret their choice to frame him, but he had killed them when he found them laughing. Kōga admitted that even after killing them, he was still filled with anger for what they had done to him and the humiliation he had endured."

"And the is the start of his own rebellion from the higher-ups, deep down, Koga felt that those who are in a higher position can easily manipulate everyone,"

"Eventually, Yamamoto and Ginrei confronted Kōga, and after an exchange of words, they realized that they could not get through to him. They engaged in a minor battle, and Kōga tried to release Muramasa with no results. The two captains decided to take advantage of the situation, and sealed Kōga away when they realized he had lost total access to Muramasa's power."

"We don't know what really happened on that day, why Muramasa never materialized, but what we know, Koga hatred is not only to the Shinigami but also to their own Zampakuto."

"Kōga's revolt was never recorded in Soul Society's history. After all, this is a huge scandal to the Kuchiki Clan and the higher ups of the council."

"If that really happens, then why is Muramasa trying to find Koga?"
