The Sandevistan From Kuoh

Cyberpsychosis

Underworld, Diodora's Final Room

[Y/n]...i love...you, those words echoed in his mind as he sat on his knees looking at the ground. He barely heard his friends screaming his name as they ran over to him.

"[Y/n] it'll be ok, she may not be dead" david tried to console him because he saw him glitch out a fuck ton

Koneko hugged him and so did everyone else since two of them feared he's about to lose it. He was about to calm down until laughter filled the room as a familiar face appeared in front of them.

"Hahaha didn't i tell you, your actions have consequences and look what happened poor little rebecca died because you" shalba taunted

"It...was my....fault" [y/n] muttered which caused him to glitch out more, a heart beat moniter was beeping

"Enough, you dare to take away the happiness of [y/n]" Issei was furious and was glowing green

"Oh pipe down, if he wishes to see his gf again, just officially join the khaos brigade, but it was enjoyable to knock away the sekiruutei's hand so that she did die" shalba said with a smile

While everyone was defending and preparing to attack shalba, in the mind of [y/n] was a deep abyss of darkness.

'You failed to keep your promise [y/n], you failed to protect rebecca' Bilar was a pitch black mass standing over him

'You became weak, you couldn't help rebecca, all you did was fuel the fire of trouble' kiwi was the same as bilar

'You failed to save me and then didn't save rebecca even though you could've easily done so with the sandevistan you use, but i guess its all just vanity' Falco said

'Why didn't you help me [y/n], i died because of you, i hate you, and i will never love you again' Rebecca said

'You lost [y/n], let us handle it from here, the people of the blackwall will always have your back'

[Y/n] slowly sank into the tar filled ground until he was submerged completely, and on the outside he finally stopped glitching out.

In another world however, with wakako okada, she felt a wave of dread and slightly clenched her shirt where her heart is "oh [y/n] what happened to you"

"[Y/n], are you ok, i mean in a sense you're not glitching out" Lucy asked

Everyone was met with a stare of what they could only depict as insanity, his eyeballs were black and his pupils were red "cyberpsychosis! Everyone move away from him" david ordered

Koneko didn't budge until [y/n] mumbled "move away from the boy, the rogues like you too much to see you go" the moment she let go he disappeared from view

"He's gone!" The others panicked before seeing shalba getting smashed downward from above.

Shalba got out of the way before [y/n] stomped his foot where shalba's head was "this was not part of the plan, he was supposed to fall into despair and join us"

[Y/n] was glitching out and activated the sandevistan, kicking shalba in the gut, sending him through a pillar

'You're a failure boy, just like your parents' the voice of smasher mocked him

"Then can a failure do this" he muttered before opening five compartments. He then placed 3 different bullets giving him attributes of Magic which were Dragonslayer, God Slayer, and Devil Slayer enhancing his technology with magic.

The devils in the room started to shiver and sweat from magic suddenly leaking from him "m-monster, i must flee" shalba tried to teleporting away but was smashed through the wall
