In its sealed form, Mirokumaru resembles an ordinary katana. It has a red hilt and a square tsuba.
Previously by activating her Shikai at the time of when she was only an afterimage, her Zanpakuto took the form of a Khakkhara with a pointed tip when released.
Her khakkhara had four rings and with those, she could control leaves, wind and lightning there was a 4th element but unfortunately, she couldn't bring it out...
When she was revived, Senna's Shikai changed from a Khakkhara into two smaller versions almost 80cm each with one ring on both of them and smaller rings hanging from there...
It made it easier to control her elements one wind and the other lightning accompanied by leaves...
She had realised that her new Shikai was the true form of it and had 2 big rings one of each Khakkhara and 3 smaller rings accompany them...
Meaning she had 4 rings on each Khakkhara... She had realised that two of the smaller rings were helping her summon the leaves and manipulate them...
As for the other 4 she was clueless, perhaps it had something to do with her last element which according to what Sora had told her there was a chance it was water...
According to him, one Khakkhara gave her the ability to summon Wind, Lightning, leaves and water while the other helped her control them...
After training for these last 6 months, Sora's words rang true but unfortunately, she still hadn't been able to summon water even now...
As when her shikai took form, countless leaves appeared and formed a wall as each Cero crashed on them causing an explosion to happen while raising dust...
When the dust died down Starrk was shocked to see that the wall was fine and well after his Cero's found their mark...
Senna: "God damn it that was hard to keep up with!!!"
Senna: "Pretty much all my leaves got evaporated..."
Sora: "But you can always summon more no??"
Senna: "That's super hard you know....."
Even though she complained Senna waved her Khakkhara and more leaves started appearing replacing those that got destroyed in the clash...
While doing all that everyone who saw her thought that she is playing around and it was true considering she wasn't sweating at all...
Leaving to take care of Yammy who was on the mercy of Komamura's Bankai trashing him around and Kenpachi's Shikai cutting pieces of meat each time he swang his giant sword...
When he was freed by the flames and with his peak of anger Yammy almost healed himself in 2 seconds unfortunately for him the others weren't going to let him...
Hachi found his chance to activate his mask again and started sealing Wonderweiss inside as he was still fighting the black flames with his body alternate between dark grey and white colour...
Hiyori and Lisa had gathered up the wounded which was Hisagi, Hitsugaya and Kensei although for him they were minor wounds and also told the other Vice Captains to gather around as not to get in their way...
The first to join in their little gathering was Omaeda earning a glare from Soi Fon who struggled to keep up with the new Grimmjow...
Soon the rest joined and Sora saw, Rukia, Matsumoto, Renji and Iba there while nodding his head before he turned towards Aizen...
Sora: "Shall i make a move against your few selected people or want me to come at you??"
Aizen's face had long ago become serious from when Senna blocked Starrk's attack...
He scanned with his eyes the whole battlefield and saw 15 people still standing in his way to supremacy...
If he added those that left the game they were 9 more which were trash in his eyes...
Aizen: "Neither of the above... As I will be coming to you by cleaning up this huge line... Sora-kun."
