Deku:
DASHING!!!

[ As Deku dashes in to attack... Kirito dashed into clashing Deku head-on - Then he secretly signals Asuna and Yuuki... ]

CLASHED!! CLASHED CLASHED CLASHED!! THUD!!
SLASHED - MISSED! THUD - SWEEPS - ROLLED! JUMPED!!

Kirito:
~"(He's slowly getting stronger every swing. I have to hit him as hard as I can to deliver damage to him!")
~"Haaaa!"
CHARGED UP SWORD - VORPAL STRIKE!

Deku:
"Hmph-!"
CHARGED UP SWORD - VORPAL STRIKE!

~SLOW MOTION - CLASHING!!

FLASHED!!!

[ Flashback ]

Deku (SAO):

"(Why Kirito's always alone? I... just wanna help him out so... he won't be alone anymore... He always go solo - I don't... want him go risking his own life... I wish I was fast enough to decide to let him join our group sooner..." Deku looks a bit sad as he sees Kirito was all alone... he tried to reach out but he'll only Ignore him

[ End of Flashback ]

~Kirito:
"Huh?!" Kirito was surprised as he sees a flashback
~Deku:
"-?! ...!" Deku was also surprised as he sees a flashback but he pushes Kirito back
CLASHING - THUD!!!

[ The swords clashing against each other and then suddenly a flashback of Deku's memories - Both are very surprised at the moment but Deku ignores it and sends Kirito flying a bit further away - ]

Kirito:
"Woah!" Kirito regained his ground and leaps back to Asuna and Yuuki. "What just... happened?!"

Asuna:
"You're okay, Kirito?" Asuna said to Kirito as he was so surprised. "What happened? You and Deku were both surprised at something."

~Deku:
"(What just happened? As soon as I tried to counter his "Vorpal Strike" with my own - Wait?! -") Deku remembers what Deku Black said beforehand
~Deku Black:
("Oh... and let me tell you all this. When there are powerful swordsman and swordswoman at there in this world, they can read each other's thoughts/minds and feelings simply just by clashing swords with each other... without ever uttering a single word.")
~Deku:
("Could it be what Black said before - That means... the clash just now. It means... Kirito and I have gotten stronger... and he - No, we was able to read my mind... and my feelings of back in SAO. The more we fight... the more we can read each others thoughts and feelings...") Deku was silent for a second.

Kirito:
"I happen to... have seen his memories!" Asuna and Yuuki were surprised. "I believe it's what Deku Black said earier. But... I tried to hit Dekarusu hard enough to inflict damage to him but he countered with the same sword skill and then... I was able to read his thoughts and feelings. Maybe if we all hit him hard enough... maybe we can reach out to him! I hate to do this but no holding back!" Asuna and Yuuki understand of what Kirito was talking about

Deku:
"(It's like the old saying - "We let our fists do the talking." "But this time... our swords will do the talking for us... but it doesn't matter to me anymore because - I abandon my friends for my family's deaths! I wasn't strong enough to kill Black! I even harm and barked my friends who tried to help me out with this Curse Mark - Either way I'm such a scum - Even more than scum. But I need to hurry up and finish this, I can't waste any more time!") Deku said as he sees the others ready to fight.

Yuuki:
"(The harder I hit, the more I can reach him! This is the first time I've fight in a battle against him... but of course I'll fight him all I got!") Yuuki was getting serious.

[There should be a GIF or video here. Update the app now to see it.]

Deku:

"I hope you guys are done chattering nonsense!" Deku used the Curse Mark and it spreads more on his body and he dashed off to the others

Yuuki:
"I'll go first!"
DASHED!!

[ Now it starts with Deku and Yuuki - the two were once together but now facing each other for the first time ever! ]

CLASHED!!! CLASH CLASH - HIGH-SPEED CLASHING!!! DOUBLE STUD - FLASHED! CLASHED!!

"Hmm!" Deku smirked
~Yuuki:
"(Dekarusu! Please! Just let us reach you!)"
GRINDING - SWING - DUCKED - LEAP BACK!

Deku:
STEP - DISAPPEARED!

~Yuuki:
"Huh?" Yuuki was surprised as Deku disappears in a instant. "(Where did he go-?!")
~Asuna:
"Yuuki! Behind -

~SLASH - CLASHED!!!
~Yuuki:
("So fast! If I didn't react then he would've killed me!")
CLASHED CLASHED CLASHED CLASHED!! THUD!! CLASHED!!
"Switch Asuna!" Asuna was behind Yuuki instantly

~PARRIED - SWIFT!
~Asuna:
"HYAAHHH!!"
FAST THRUSTING!!

Deku:
~EVADING - REFLECTING!!
"(They're at the class of their own now! Their Speed, Agility, Timing - Everything has improved! This'll be harder then ever but it's good to test my strength!)"
~REFLECTING - THUD!!
"Burst -"

Kirito & Deku:
"Element!"
"Element!"

~DOUBLE SHOOTS - BOOM!!

~Deku:

Kirito:
"HYAAAHHH!!"

~CLASHED!!! MULTIPLE CLASHES -

~Kirito:
"Dekarusu! C'mon man! What's the point of this?"

"Just say it! It's okay to let your feelings out dammit!"

Deku:
"I've been let my feelings out not too long ago! Can't you dumbass see-?"
MULTIPLE CLASHES -

CLASHED - THUD!!!

~Asuna:
"But we're your friends, Dekarusu! We just wanted to take you back-!"
LEAPED - CLASHED - REPELLED - POW! CLASHED!!! GRINDING!!

~Yuuki:
"Exactly!" Yuuki clashed her sword against Deku's. "The reason why you're doing all this is because of your family's deaths! You wanted to get revenge!" Yuuki said as Deku's eyes widened a bit.

Deku:
"!!!"
CLASHED CLASHED! SWING - EVADED THUDDED!!

Kirito:
DASHED!!!
"Dekarusu!"
CLASHED!!
"Just stop and think about it! Think about what your family think! They don't want you to go through this!" Deku's eyes widened and he clenched his teeth!
~CLASHED CLASHED CLASHED - GRINDING!! THUD! BOOM! THUD THUD - CRASHED!!

[ Kirito managed to outfight Deku as he was able to send Deku flying and then get crashed into the wall while clashing against each other... then Deku remembered his family's faces and then he was enraged - ]

Deku:

"Shut the hell up, Kirito! You got some nerve to talk about family and shit!"

Kirito:
"?!"

Deku:
"What the hell you know about me and MY family! It's not like YOU ever trap YOUR OWN family inside the death game in first place-!" Deku couldn't control his emotions as his tears immediately burst down his cheeks, then Kirito was surprised to see him crying his anger out
TEARS RUNNING!

"YOU AND EVERYONE ELSE WERE ALL ALONE RIGHT FROM THE VERY BEGINNING OF THAT HELL!!! WHAT MAKES YOU ALL THINK YOU ALL KNOW ANYTHING ABOUT THAT SITUATION, HUH?!" Deku barked his whole life to Kirito, as he couldn't hold anything back any longer. Then everyone started to stop their actions and listen to Deku's livid and sad voice. "I'M SUFFERING RIGHT NOW BECAUSE I HAVE THOSE TIES! I'M SUFFERING RIGHT NOW BECAUSE OF MY OWN FOOLISHNESS! MY OWN MISTAKE-!"
CLINC - THUDDED!!
"SO HOW THE HELL CAN YOU PEOPLE COULD POSSIBLY UNDERSTAND... TO WHAT IT FEELS LIKE TO GO THROUGH ALL THAT! SINCE DAY ONE, I HAVE TO LIVE WITH THAT DISTRESSFUL FEELING LIKE IT WAS HUNTING ME! I WAS ONLY FOCUSING ON SURVIVING WITH MY FAMILY AND NOTHING ELSE! THE ONLY THING THAT I TRULY REGRET IS TRAPPING MY FAMILY AND WASTING TWO YEARS OF OUR LIVES! THEY WOULD BE ALIVE RIGHT NOW AND THINGS WOULD BE COMPLETELY DIFFERENT NOW IF IT WASN'T FOR ME!!!" As Deku kicked Kirito off of him, then he let everything out of his system.

Deku Black:
~"......" Black sense Deku's emotions through the Curse Mark.
"(Damn! His emotions exploded... it's too much for me to handle...)" Black secretly wipes the tears of his eyes.

[ As Deku finally revealed his true feelings... everyone was completely silent after hearing Deku's words... ]

Asuna:
"Deku~Kun..."
Yuuki:
"Deku~Kun..."
Alice:
"Deku..."

Kirito:
"...Right."

Deku:
"..."

Kirito:
"Yeah... you're right... after everything you've said... yeah. I don't understand because I was all alone, all by myself. Since from Day one of that game... I bailed on you and Klien that day... but since then I did appreciate you trying to be there for me... and I wanted to return the favor, that's why I'm doing this. Because we're friends, you tried to reach out for me and now it's my turn to do the same - Even if it's the last thing I do on earth." Kirito hold out his hand.

Deku:
"..." Deku remembers his family's smiles, then he also reaches out his hand as well. "Aerial Burst!"
BOOM!!

[ Deku's Burst Element sends Kirito flying over at Asuna and Yuuki... then Deku was slowly walking towards the others... ]

Deku:
"...Now you guys are happy?" The others were silent. "Now you all know what's wrong with me... I wanted was to have a good life with my family... that's all - I don't care about anything else... but... then... I got to know all of you... and... I truly enjoyed it. Every single one of you. But... I just can't anymore ok."

Asuna:
"But, Dekarusu... it's ok to love your family and wanted to do everything you can in your power to make sure things are going smoothly for them... but you also have other people who will be there for you - Like us. No matter what, you can lean on us whenever you're feeling down."

Kirito:
"We all have our fair share of making mistakes and how we tried our best to make it up for it. But not all mistakes can be fixed. So of course we understand each other's mistakes but different."

Yuuki:
"Just like now - The mistakes you made was leaving us behind and saying you wanted us to forget you and wanted to sever our bonds! It's not too late for you to come back with us, Dekarusu." Dekarusu shook his head after hearing Yuuki's words, then he wiped his tears away from his face

Deku:
"It's too late Yuuki... it's WAY too late. I can't turn back now... I made it this far and I can't stop now until I finish things!" Deku said as he charges up his sword. Then the others are prepared for a big attack. "I already harm you guys before... and it really hurts me even more than now... I really hate myself for that... but since this Curse Mark has taken over my body... I don't want to take it to another level but if I must  - I WILL -"
DASHED!!

Kirito, Asuna & Yuuki:
CHARGING SWORD SKILLS - TRIPLE DASHED!!!

~Yuuki:
"(Thanks for Miss Cardinal's support... I've perfected my Original Sword Skill to a new level and I was able to teach it to Asuna just in case of an emergency. Now, I can do this Skill willingly and I can do it differently from the original! I hope this works!)"

Deku:
"Spirit Excalibur!!"
SWORD SHINES - GROWING!!

Kirito & Asuna:
"Hyaaaahh!" (Kirito)
"Haaaaahh!" (Asuna)

Deku:
"DYAAHHH!!"

~Yuuki:

Kirito & Asuna:
"HAAA!!"
"HAAA!!"

FIRECE CLASHED - FLASHING!!!
