The tired weapon

Kuchiki Kiyoko from with her Zanpakutou, Daiichi - yes, this child - after fight.

So I can say something about him.
He's very young just because Kiyoko "roused" him really quickly to his Shikai form. In this couse he doesn't change his sword's form when he is in Shikai too - he's still a katana. His new skill in this form is a little strange - when he touch somebody, this person doesn't feel nothing by his/her skin, for exemple that he/she's handing a sword or something like that, and a foe is really confused and doesn't know what he/she can do. But Daiichi is only a child and he get tired quickly. Kiyoko must defeat an enemy as soon as it is possible. She likes that method of fighting (she wants to vanquish her opponents without makes their pain, in humanitarian way - she concentrate all of her reiatsu in one strike), so everything is good.
The reason that Kiyoko "roused" her Zanpakutou too fast is relative with her illness. At heart she's dying. She doesn't get old like shinigami but like people, so she doesn't have enought time to get better as soul reaper, she must hurry up. Nobody can help her in Soul Society, I think maybe Orihime can do something for her. Or Kiyoko must find a vampire and let him bite her. Now she only can do a ritual with her Zanpakutou - she's putting across her years to Daiichi and she's getting younger, but isn't a solution because in this way in the future Daiichi will be too old to fight. Has anybody idea which can help her?

OK, I said too much, sorry for that.
Hope you like it!

PS. I think that it is really hard to be a tree in Soul Society.
