CH-1

The sky that shown the rising sun and the pearl moon with glittering stars had turn grim black, the river whose water glitter during day and become mirror at night now runs red, the lush green land turned into charcoal and ashes, and the air that vibrate from magic had been tainted with evil mana that emit from the Devil king who turned the this paradise into hell.

Despite the hopeless situation the brave soul still try to keep the Devil at bay. The princess of fairies Yaoyorozu Momo, the queen of the witches Uraraka Ochako, the commander of knights Iida Tenya, the leader of dwarf Kirishima Eijiro, the prince of the empire Todoroki Shoto, the king of the wild and dragons Bakugo Katsuki and the hero who hold the power to extinguish the Devil Midoriya Izuku still stand between the devil and the world of living.

"K-Kacchan are y-you ok?" asked the mangled and bleeding hero to his childhood friend who himself was lying on the ground beside him and doesn't seem to fare any better than him.

"Shut the fuck up Deku" The dragons king hoarsely replied while wobbly standing up "Do you think this weak ass attack will take me down hah" He smugly said while cracking explosive magic from his hand.

Midoriya Izuku looked at his dearest friend shaking, bleeding, bruised but still ready to fight. The fire to win, the confident to be victorious in his eye isn't dim but first time in the long time Izuku could see the fear mix in them. It had been long time that Izuku seen those eyes it was perhaps the day when Izuku decided to part with him when they were teen, to end their relationship that he saw that look in his eyes, the fear of losing the most precious thing in the world. Izuku knew that fear because he felt the same at that time perhaps that's was the reason that he was incapable of leaving him after all this time. Even when the world won't accept their relationship, even when Katsuki was the king who had to perform duty to his clan and Izuku was the son of the simple healer.

But who knew that Izuku would be the hidden son of the previous hero who sealed the Devil previously that Izuku himself have to perform the task that his father All Might was not able to achieve at that time and lost his power during his battle with the Devil. Which brought Izuku to today's dilemma.

Izuku looked around to see if his other friends are up for the fight but the sight that welcomed him brought the worst dread he ever felt in his lifetime. Many of his friends were unconscious and bleeding but the few have lost their limbs and other shown the sing of not breathing. This cause Izuku to shake from terror 'wh-what the hell' He thought 'Todoroki- Kun, Iida-Kun th-they are not moving at all not even breathing. Yaoyorozu-San, Uraraka-Chan, Kirishima-Kun are bleeding really badly if they didn't get help they will die'

"De-"

This is my fault'

"-ku"

'If I was strong enough'

"-ku"

'This wouldn't happen'

"DE-"

'I failed them'

"OI"

'I let them die'

"-KU"

'I COULDN'T PROTECT THEM'

Before he could process any further Katsuki grab his collar roughly and bring his face to himself and yelled "ARE YOU LISTENING SHITTY NERD?"

"K-Kacchan" Izuku stammer as he looked at the frenzy red eyes "Ki-Kirishima-Kun, Iida-K-kun they-they are..." before he could finish the sentence Katsuki punch him in the face. This punch was not as hard as it was in the past but it was enough to stop Izuku from breaking down.

Katsuki look down at his childhood friend and lover. He knew that this is an hopeless situation, he knew that many of his closest friends are fighting death, he knew that few of them have already gone from this world but even if he knew all that Katsuki will not give up, he could not give up because his most precious person, the closest to his heart is still living and as long as Izuku is alive Katsuki will not go down without a fight.

"SO WHAT? HAH...THEY KNEW WHEN THEY JOIN THIS WAR, THEY KNEW WHAT THEY WERE AGAINST, THEY KNEW THERE IS A POSSIBILITY OF LOSING THEIR LIFE YET THEY CAME" Katsuki yelled with all his might at Izuku that even the saliva mixed with blood was spitting on his face "YOU" He again grab Izuku collar and bring him face to face "You-you are still alive...you are still able to fight right?...as long as you are breathing there is still hope...their still a chance that we could win" Katsuki looked at his emerald eyes that always shining, always looking at him as if he was the only person in his universe, they were always filled with so much love that Katsuki sometime forget to breath. But right now those eyes are filled with guild, sorrow, shame and most of all fear, brimming with tears looking at him in desperateness, they were nothing like the emerald orbs that he love the most about him "don't waste their effort...fight and win...so that their scarifies won't go to waste...fight you shitty Deku...don't give up now...I'm still here...fight" Katsuki whispered the last word as he laid his head at his shoulder unable to look at depressing eyes of his.

"Kacchan..." Izuku looked at the blond hair to his right but before he could say any further a deafening roar that shaken the ground was heard.

Izuku and Katsuki look at the direction of the roar and saw the Devil recollecting itself from the last attack.

"Tch, bastard couldn't remain dead hah" Katsuki gritted while standing up facing the direction of the Devil "Well seem like it's now our job to kill this bastard...OI get up Mr. Hero or you want me take all the glory for killing this shit all alone".

"Kacchan" Izuku softly whisper while looking at his lover with hesitation and fear 'Kacchan is not in the condition to fight any more, his magic had been worn out in the last collaboration attack' Izuku then look at the Devil trying to stand up 'Even the last attack was not enough to take it down…..the Devil have the regeneration ability he would be up at any moment now. Kacchan and I are not able to defeat him in our current condition even when e-every o-o-one' He look at his dead and dying friends 'w-we-we couldn't win' his eyes started to flow with fresh tears as he clench his hand into fist and started to shake at his powerlessness.

'What should I do?'

He remembers the time when he goes to the adventure with his friend.

'How can I defeat the Devil.'

He remembered the loving moments he spends with Katsuki.

'Think.'

He remembered the time which he spends with his kind mother.

'Think Midoriya Izuku think.'

He remembers his father All Might that he admired from the bottom of his heart and suddenly he recall what his father has told him about the Devil. A method that could end the Devil existence but that method required sacrifice from the user life-force, and remain of one for all previous vessel right along with the current holder of one for all body as well. It could bring back the one that is lost and heal the one that is broken he could save every in exchange for his life as well as defeat the Devil.

Izuku looked at Katsuki 'the spell is tricky and casting it took some time and the exchange cost is too high but if I could save him…...save them I will do it' With new found determination Izuku grip the sword his family heirloom given by his father and stood up 'I will succeed'.

"Kacchan" Izuku barely whisper

Katsuki could tell something was off about Izuku tone nevertheless he still replied "What?"

Without saying a word Izuku pulled Katsuki towards him and kissed him on the lips. He kissed him with all the might as if he was trying to convey all his feeling through this single kiss desperation, guilt, regret, and love that he couldn't say it through words.

Katsuki was stunned for a moment before he felt something was wrong with this kiss. It was not passionate or wistful kiss they shared before but something like it is last loving act they will ever share, like they will never see each other after this, like a goodbye kiss.

But before Katsuki could react he felt his remaining strength fades away "W-what the h-hell?" He looked questioningly at Izuku with fear that he stubbornly tried to hide "What have you done Deku you bastard?"

"Thank you for everything Kacchan" Ignoring his question Izuku softly said to him "I wish we have more time together"

On hearing those words Katsuki felt the terror run through his body "Wh-what the hell are you talking about Deku...we have time after we take down that weakling we have all the time in the world to be together we..."

Katsuki stop after looking into Izuku eyes. They were overflowing with emotions, emotions that he felt during their kiss sadness, grief, guilt, love but now there is determination too, determination to sacrifice himself to save others. Katsuki has seen that look countless time when they fought enemies and after every fight Izuku would always come worst among all his comrades but this time the enemy is too strong way too strong to deal alone.

"It's ok Kacchan"

"Deku"

"I know a way to save everyone"

"Hey"

"Though I won't be with you all"

"S-shut up"

"But I will be watching"

"Don't speak shit you bastard"

"Kacchan"

"I love you" Izuku lovingly said "live well in the future...live for me too...goodbye" after saying his last farewell Izuku walk towards the direction of the Devil without hesitation.

"Oi Deku you bastard come back" Katsuki growled "I could still fight you fucking bastard" he tried to move his body but it's in vain "what the hell you have done to me" Katsuki look at the Izuku figure which was getting further and further away "what the hell are you thinking don't look down on me you bastard I could still fight...undo this spell YOU FUCKING BASTARD" Katsuki yelled but Izuku didn't halt or even look back, he kept on moving towards the enemy. Katsuki tried to call Izuku one more time "AT-LEAST LET ME GO WITH YOU IDIOT" But Izuku still didn't stop.

Izuku could hear desperate cries of his childhood friend and lover but Izuku didn't have time or energy to focus on them instead he started to hear the echo of his father words and started the chants. As he chant he could feel the previous vessels magic through the sword.

"This sword is passed down in our family for generation and only the vessel of ONE FOR ALL can use it."

Izuku focus on the core of the magic in his body as he kept walking.

"This spell will help you control the magic in the nature with the magic in your body."

He started to convert every part of his body into magic indicator.

"But as you use this magic you need to sacrifice parts of your body depending on the number of people you want to save, area of efficiency as well enemy's strength. The bigger the objective the bigger the body part will be scarified."

Izuku entire body started to glow in green as he was almost done with the chant.

"This spell can bring back that once was lost and defeat the enemy and restore the balance to the world. That's how powerful this spell is"

Izuku bring forth the sword in front of him. At this point the devil could sense a powerful magic is been cast more powerful than before more powerful than him.

"When you cast the magic remember that the sword that is pass down from generation from generation become the key to magic circle. Hold it in your both of your hands and remember your origin then scream in your heart through your guts."

The casting spell could be seen below and above Izuku. The Devil recollected himself and prepare for the counter but it's already too late.

The center of magic circle above Izuku was at the tip of the sword; it acts like a key ready to unlock the spell. Izuku took a deep breath and involuntary shouted the words that he screamed in his mind right along with the echo of his father words.

"ONE FOR ALL FINAL JUDGMENT."

"ONE FOR ALL FINAL JUDGMENT."

After the words had been said he thrust the sword into the magic circle and turn it to unlock the magic spell. The magic circle started to glow right along with his body, it started glow brighter and brighter until not the a single fragment of Izuku body remained and then the ball of light busted into gentle glowing fireflies, scattering around miles healing, restoring, bringing the dead back to life and ending the Devil and it follower by turning then to dust, doing miracles whatever whomever they touch they do so according to the wishes of the caster.

When the glowing light dim and the wish of the caster have been fulfilled, the sleeping one started to wake up.

Katsuki blink the confusion from his eyes and the first thing he recalls on waking up was Izuku body disappearing right in front of him before he fainted. He looked around his surrounding but it had changed to its previous condition before the war. The one that died came back to life and the one that injured had been healed, what was destroyed had been restored. He look at his own injuries but none was found but despise been healed and having his friends back Katsuki didn't feel reviled on the contrary he felt a sense of dread fill his heart.

He looked around to find his lover but couldn't spot him, he look again and again but he couldn't see him until he spotted a similar shining object in a distance. He ran toward it believing it to lead to his childhood friend, his lover, his Izuku but it didn't. The sword was there but not its owner instead there was a red necklace made of dragon fang wrap around it. Katsuki knew that necklace how could he not after all he was the one who previously owned it before he had given it to Izuku as the token of his love.

At that very moment realization broke Katsuki into pieces. He knee down and hug the sward wrap into the necklace.

He didn't cry.

He didn't scream.

But he couldn't breathe.

He hugged the sword so tightly that the edges of the sward started to dig in his flesh. He didn't registered when his friends came over to him, he didn't recognize their concern voices, he didn't notice when he started to bleed and he didn't know when he fainted again. But he knows one thing before darkness took over and that is that Izuku is no longer alive.
