This is going to be the last chapter for this story. The reason is just that I don't feel any motivation for this and certain things I planned for wouldn't work out as I don't know to much about FGO.
I haven't played the game for many reasons (mostly because I saw spoilers and it wouldn't be fun with all the spoilers I saw) and because of that, certain things I wanted to happen would be impossible or wouldn't make any sense.
So this is the final chapter and I am sorry for how bad and short it is.
'W--where am I' Ritsuka thought to himself as the sound of ringing in his ear was heard and he pushed his body up.
His left arm was pitch black and barely held the form of a human arm. Ritsuka also had injuries cover his entire body, his clothes which also served as a defense ripped apart and only had one command seal left.
He looked around him to see buildings destroyed and bodies surround him.
"Al--ter" Ritsuka called out to one of the bodies laying on the ground dead, which was his Alter self who gave him his arm.
"MASH--U" Ritsuka yelled out in worry
'PLEASE, DON'T BE DEAD' Ritsuka thought as he started looking for her though the corpses around him.
"..Mashu, NO NO NO" Ritsuka repeatedly yelled as he saw her body and ran to her
He took some debris off her body and held her body up close to him, but her body didn't show any reaction.
"Come on, not again, not again" Ritsuka said as he moved her hair away from her face and her entire neck was twisted, leaving her expression into one of agony and pain.
"ENUMA ELIS--" the one who has been defending Ritsuka's body yelled out the name of his Noble Phantasm but was cut short as a beam cleaved his entire body in half.
Ritsuka turned to look and saw the body of a king with golden hair who always acted cocky spilt into two halves.
"GILGAMESH " Ritsuka yelled the name of the one who protected him
Then, a beam had been fired at Ritsuka and his body reacted by pushing him away.
As the beam had been fired, it cleaved through the body of Mashu and her organs started to flow out of the area her entire body was cut.
"MASHU" Ristuka yelled out in terror at what he witnessed as he looked at her body with her organs and brain spilling out onto the floor as he grabbed his mouth so he wouldn't throw up.
While still keeping his hand on his mouth, Ritsuka glared at the one who caused all of this destruction and death.
Ritsuka's left arm then started to expand into a red barbed spear as he stopped holding onto his mouth and gripped the spear.
He was able to do that for one reason. That was because the arm of Ritsuka Alter was given to him by Angra Mainyu using his wish granting abilities when he was still alive. That allows the arm to recreate any corrupted or evil weapon of any heroic spirit.
The one who killed Ritsuka's friends only looked at him with a grin, as if they were amused by his actions.
Ritsuka shakingly moved his tired and weak body into an offensive position as both of his arms gripped the spear. Then with all his strength in his body, he threw the spear at his enemy.
"GAE BOLG" he yelled out the name of the Noble Phantasm he was copied from a certain corrupted Irish hero.
Though, that Noble Phantasm was no match for the enemy infront of him.
All of a sudden, Ritsuka's body had sprayed blood from his wounds and his left arm lost any semblance of shape.
His magic circuits started to flare, making him feel excruciating pain as his magic circuits started to destroy Ritsukas own body.
"Mashu" Ritsuka said as he saw himself where he was a moment ago, holding onto the body of Mashu with her neck twisted.
"Y-you can't be here. Solomon" a demon pillar said in surprise as an adult male with orange hair and a white coat walked up to the demon pillar.
"You better make sure not to die, kid" a lancer in blue tights told Ritsuka as he went into an offensive position with his spear glowing red.
"I guess I am returning to my life as a Counter Guardian. Thank you for the time here" a red bowman told Ritsuka as he pulled his bow back with a spiral sword that was made into an arrow.
"Senpai, I love you" a pink haired girl told Ritsuka with a smile on her face as she held up a shield against a blinding light.
'NO NO NO NO NO NO NO. PLEASE STOP, STOP, STOOP'
Ritsuka's kept smashing his head on the ground while he started laughing like an insane person, because, he had went insane.
The reason for it was that Ritsuka was now suffering the consequence of using his Alter's arm. That was to suffer through his worst memories over and over again until his death as well as having his own magic circuits destroy his own body.
It didn't take long for him to die as his body was cut in half by a bright beam which brought a burning sensation that could never be described by mere words. For the beam burned his organs, skin and his blood vessels themselves when it came into contact with them.
All while his face of complete and utter insanity wouldn't leave no matter how much pain the burning bright beam brought him.
