Yeah and Shunsui was right.... So Shunsui wasn't going to use it. Shunsui was joking around and Ukitake took it seriously, and we have seen that Starks cero does absolutely no damage to Shunsui.
Yammy was slow and not Stark..... Stark had power and intelligence which made him far more dangerous than Yammy.
While Ukitake and Shunsui fighting together they weren't even trying to kill Stark. They were still as casual as ever, the only time Kyouraku got really serious was in their last battle in which Shunsui killed Stark. The other times Shunsui was making half assed attempts at killing Stark in which even his expression was casual.
OMQ got a hit on Shunsui by nearly getting killed..... Shunsui nearly sliced him in two while in Shikai and OMQ had to use Vollstandig to dodge it and hit Shunsui, it wasn't even a killing blow. Even after losing an eye Shunsui still bypassed his defences easily and got a hit in and the only reason he got shot down (Again not even fatal injuries) was because Yama died.
Don't even need to explain Yama.... In the databooks Kubo indicated that their fight ended as a draw not as unfinished while other fights that didn't finish he said it as so.
No he was going to use it he had no choice he won't joking around so what you talking about? He could not get close to starkk unless he had help,starkk cero don't have to hurt him the whole point is tht kyoraku had no way to get close to him,an his cero will hurt kyoraku if he keeps getting hit by them if they did not hurt then he would just run threw them an not worry bout getting hit...no matter how you put it yammy was stronger but yea starkk was strong aswell.
Yea they were trying espacially kyoraku he tried to kill starkk foreal when he was arguing with his gun right arter he did his release an when starkk was focused on ukitake kyoraku tried to cut his head off,they weren't playing around they just could not hit starkk while he was useing his cero guns.
An yea he killed starkk thanks to that sneak attack that got rid of Starks wolves Stark could not use his real power in their final battle.
Well yea he actually got hit but Byakuya did not an the only reason he cut OMQ was cuz Yama raised his spirit by entering the battle,an the fact he did not beat OMQ yet even after Yama delt with fake Bach also says alot about kyoraku strenght...an omq won't even using vollstanding anymore an kyoraku still could not beat him smh.
Lol the funny thing is,is that the fight was not finished cuz they were still fighting...anyway Yama was not serious about killing thoes two as he was about killing the Quincy if so they would no longer be around an, if they fight would have dragged on Yama would have eventually won.
