Just a tad before the spears connected with each other, Sora used his clone along with the doors to replace and protect himself and create a square like a tower covering all Arrancars and his clone, that was when the explosion occurred...
Instead of a cross explosion, because of the redirection of the Doors, the energy blasts entered one door and went back to the Arrancars hitting them constantly and killing them leaving nothing behind...
By doing that one after another explosion entered a Door and went out through another raising upwards towards the sky..... From afar it looked like a pillar of flames rising in the sky and it was what the others saw...
After a few seconds, a creak was heard and all Doors burst to nothingness leaving all the energy that had been built inside burst like a balloon causing energy waves of heat to travel far away from that spot and was about to reach Captain Unohana, Captain Mayuri and the others...
The three students were scared shitless while Dondochakka and Pesche turned their back to protect Nelliel from the waves as they were upon them... It was then they felt two movements....
Unohana: "<Bakudo Arts 81 : Dankū>"
Mayuri: "EEEiii making others do your job how annoying... <Bakudo Arts 81 : Dankū>"
As they were about to be hit by the blasting waves Unohana and Mayuri created two transparent walls side by side connecting each other, blocking the heat and letting everyone breath a bit.....
After doing their jobs everything calmed down.. cracks could be seen on the walls the Captains created and were quite lucky a bit more and it would have passed them hitting them...
Everything around them returned to its former state, with no dust flying here and there and were flabbered by what they could see... Countless meters extending of burning sand... No sight of Arrancars in the vicinity neither of Sora....
As the students were searching around the Captains were on high alert when they felt a slight disturbance behind them....
A figure appeared with dried blood on his face, panting really hard and trying to catch his breath, his hands had been ripped opened and small amounts of blood were oozing out from there, his attire was totally destroyed leaving only a ripped like pants covering from his waist and down.....
Unohana and Mayuri when they saw his injuries they realized that he forced that Hado Art 91 passing the limits of Reiatsu and what his body could handle self-injuring himself.....
While Nia, Garo and Wein were thinking the same thing, he's on a different league than them and decided to seriously focus on their studies never mock anyone again....
Sora totally ignored everyone and went towards Dondochakka and Pesche when he arrived he saw Nelliel in a comatose state and was pissed off ignoring the strain he released dense killing intent shocking everyone yet again.....
Dondochakka and Pesche when they felt the killing intent even thought it wasn't directed on them they still tense up and got ready for a bitter fight that might be their last..... when they heard him speak they relaxed again....
Sora: "Put her down..."
Dondochakka and Pesche tried to listen to him but when they saw the others behind they hesitated until they heard him again...
Sora: "Don't worry if they try anything ..... They will die as simple as that!!!!"
It was then that Mayuri raised his hand and fired a Hado Arts 4, in other words, a blue lighting at him scaring them but when it got close it vanishes and crushed in front of Unohana's legs without even batting an eye to the lighting...
They nodded thinking that he will protect them by containing them but in reality, as he was walking he sent his voice to Mayuri and Unohana and a different voice at the other three..
Sora: "You three don't move a play is about to begin..."
Sora: "Heh what's with the long faces you two.... well let's leave the chit chat.... Captain Mayuri when i say you Will Die fire a Hado Arts 4 in me and when that happens Captain Unohana don't move i will send it on the ground in front of you...."
Mayuri: "Why should i help a cheeky brat like you..."
Sora: "Heh someone who was in prison and the other possess that title i believe with these words you will help... Now Then Let The Play Begin!!!!!
After being shocked by what he sais they couldn't do anything as they didn't know his identity and in the end, it happened like what he said....
