No System + No Heroine + Akatsuki
Deidara is the main character, though other Akatsuki members will also appear.
During the Fourth Shinobi World War, the shackles in Deidara's mind suddenly break. In plain terms, he escapes Kishimoto's control of the story and breaks free of the puppet's seal, determined to create an art beyond ultimate art: his own ultimate art beyond ultimate art.
After a few twists and turns, he finds Sasuke and learns that Sasuke really had been awestruck and despairing at the ultimate art Deidara had created in his lifetime. Finally at peace, he willingly releases the Impure World Reincarnation and unleashes C0, his self-detonation technique, once more. The blast shatters the Divine Tree and shocks the ninja world.
“Art is immortal!!”
Deidara's soul cries out these words before fading away.
When he opens his eyes again, all he sees is a ruined landscape. This time, in this new world, he will create an art beyond ultimate art: his own ultimate art beyond ultimate art!
And beat that damn Itachi!
