Umm Katen Kyokotsu is two parts. Katen is the tall one while Kyokotsu is the smaller one. So it’s is incorrect to state that she doesn’t have a counterpart because she in fact does have one.

Aww...poor Tobiume

My fav

Being lazy and only reviewing the last chapter. Because nineteen chapters is a lot. Anyways.
You did a great job setting up everyone's characters and the different relationships with their wielders... and how whats-his-name convinced them all in different ways... just gonna mention the ones that stood out.
Sode no Shirayuki! Rukia's! Really awesome! And Suzumebachi (A FAIRY!) was super cute. Polar opposite of SoiFun. (giggle) Poor Katen. All alone...
And then the twins show up. Awesomeness. And Byakuya-sama's bankai! Gah, he's so epic (fangirl moment). His zanpakuto had some oddly deep comments...
HYOURINMARU! Rawr! His pov on the Aizen incident (Mom getting impaled, etc) was pretty interesting. Ehehe, Yumichika's zanpakuto has a pretty tough life.
Mayuri does seem like the kinda guy that would experiment on his own zanpakuto. And another duo! Snakey and Chimpette, huh? Amusing. Very amusing. Uohana's was also pretty cool. And then Muramasa has a backstory. I feel like I should watch this arc at some point. Eh...
Such long paragraphs. Throws me off. Literally nothing like your current writing style. You're evolving, Kasai-baka! just don't turn into a butterfly!

I absolutely loved all of this. Very nicely written.:)

Yeah, Kansuke, just watch...

I really like this story. Ahahahaha!

In this chapter, I have noticed about Tenken that he is more like of a child inside but so monstrous and powerful on the outside. Such magnificent story.

Okay, this is so nice. I wonder what Muramasa feels towards Tobiume... :)

Wabisuke is so nice.

Aw! Kazeshini cares of Muramasa. Very nice story. I really like the way you write it. Bravo!

Really enjoying this fic

All their doubts emphisised by Muramasa is perfect

Dialouge, thoughts, actions and inner worlds are beyond amazing

Love Suzumebachi, that part where she cried was so emotional

I'll keep reading :D

Poor Ruri'iro. But shouldn't Hozukimaru know Ruri'iro by now? I mean their weilders have known each other for like 500 years. Other than that small thing I love this story!

A very interesting read :D

Suzumushi? wats that?

I LOVE IT!

NIce idea ! I liked reading it, but I didn't go through all chapters ( since some zanpaktou don't interest me enough ). I like how you thought of your own story about Muramasa.

I also thought that he had betrayed his master at first. I mean, that IS his power.
