Both: "Getsuga Tenshou!!!!!!"
One blue getsuga in colour and one Getsuga clad in flames clashed with each other sending energy waves here and there...
Both of them vanished at inhuman speed and clashed with their swords making sparks to dance in the air of their collision...
After countless trades of swords slashes, they appeared above in the sky with Engetsu almost getting in the range to catch off guard Isshin who still hadn't restored his sword position back...
Engetsu: "You are mine!!!"
Isshin: "You wish!!!"
He made an instant gesture with his finger pointing at Engetsu and then snapped them which caused high vibrations in the air that send Engetsu back a few steps with his sword avoiding splitting Isshin in half...
Before he could manage to stabilise his feet with the suddenly overthrown trick, he felt Isshin's reiatsu coming right at him with him being in receiving of point-blank this time...
Isshin: "Uhhhnnn..."
He slashed at Engetsu and split the air as the pressure felt and crashed Engetsu who was barely parrying the wind...
The moment he saw no Getsuga he realised that he used his reiatsu to amplify the pressure of his sword and caused the wind to rage on him.....
Engetsu: "Ugghh... Cheap tricks....."
Isshin: "Are they now??"
Isshin: "Getsuga Tenshou!!!!"
Isshin appeared directly behind Engetsu and fired his true Gestuga right at his back causing him to fly upwards...
Isshin: "I know that isn't enough to finish you..."
Isshin: "Seeping crest of turbidity. Arrogant vessel of lunacy! Boil forth and deny! Grow numb and flicker! Disrupt sleep! Crawling queen of iron! Eternally self-destructing doll of mud! Unite! Repulse! Fill with soil and know your own powerlessness!"
Isshin: "Hado Arts 90 : Kurohitsugi!!!"
With the span of 4 to 5 seconds that took for Engetsu to disperse Getsuga and the pressure of the previous slash, Isshin finished his chant as he looked at Engetsu...
Isshin generated purple/black spiritual energy, which enveloped Engetsu with a powerful torrent of gravity before taking the form of a box of black energy, covered in several spear-like protrusions that hang from the box...
Isshin then waved his hands and those spears like crosses pierced the box, making everyone look with slightly surprised faces...
Just as Isshin was about to relax he heard a voice from Inside...
Engetsu: "Blazing Getsuga!!!!"
Isshin: "Hmm??"
The black box, got slashed in a round fashion as you could see the frictions between the two and at the point of the slash appeared flames burst out as if splitting the box vertically with flames slowly burning it...
Engetsu came out with almost his clothes having huge holes but in reality, only small cuts could be seen in them...
Engetsu: "That was quite close..."
Isshin: "I thought that this might be enough..."
Engetsu: "Well not clearly enough to kill me..."
Engetsu: "But enough to wound me....."
Puchi..... A large wound opened in his back from the previous hit he got from Getsuga, blood flowed out of it which somehow surprised Isshin on how he did that...
Engetsu: "The Getsuga you fired earlier hitted directly my back while in front of me i had the raging pressure of the wind..."
Engetsu: "As i tried to disperse both and i managed to do so this happened... But the wound was smaller it ripped a bit more with the coffin..."
Engetsu: "You can say it's my loss as i can't raise my hands or activate our bankai with this wound..."
Isshin: "Then before you return... Tell me what was your desire??"
Engetsu: "To see how far you will go as you protect others..."
As he said that Engetsu became particles and went towards Isshin, who caught a sword that united with his own...
Isshin: "Why do i feel you were never in his control?? Sigh... I can really say i won like this..."
