[Bleach] After Reincarnating as Byakuya Kuchiki

After dying, I opened my eyes and found that I had become Byakuya Kuchiki?

And there was also a seaweed ambassador growth System?

Was this seaweed ambassador also someone who had transmigrated?

How was Hisana also someone who had transmigrated?

Why isn't my Zanpakuto Senbonzakura?

At least Senbonzakura hasn't abandoned me.

But then,

does that make me the only Shinigami with two Zanpakuto?

After finally saving up enough points to send Hisana and the System home,

I decided to follow the plot properly.

But wouldn't it be a waste not to use a transmigrator's special golden finger,

knowing the plot?

Fifty years passed in the blink of an eye.

On the brink of death,

looking at my unconscious adopted sister and subordinate,

I suddenly remembered why I hadn't left with my companions fifty years ago:

I had already become completely part of this world.

This story is told in first person.

Pairing undecided.

P.S. I ship Byakuya with everyone, but I haven't decided on the actual pairing in this story yet.

There will be a platonic Byakuya and Hisana relationship, but also a marriage plot. Hisana has also transmigrated. The protagonist is a bit of a troublemaker who likes to make snarky comments in his head.
