Some time later.
On a chaotic battlefield along the border between the Land of Fire and Kirigakure.
Lin Ze once again concealed himself among the clouds high above, his gaze piercing the cloud cover and locking onto several familiar figures.
Kakashi, Rin Nohara, and... a large force of pursuing Kirigakure ninja.
The scene was almost identical to the original story.
Captured by Kirigakure ninja, Rin Nohara had Isobu sealed inside her, turning her into a walking bomb aimed straight at Konoha.
To stop Kirigakure's plot from succeeding, to protect Konoha, and to protect the most important comrade standing before her, Kakashi...
Rin Nohara chose the most absolute course of action.
Smiling, she threw herself onto the Lightning Blade blazing with lightning in Kakashi's hand!
Squelch!
Kakashi stood frozen, staring in disbelief at his hand, which had pierced his comrade's chest, and at Rin Nohara's smile, filled with release and one last expression of care.
"Rin!!!"
A heart-wrenching roar, filled with endless pain and despair, erupted from the woods at the edge of the battlefield!
Hidden in the shadows, Obito Uchiha witnessed it all and felt his entire world lose every trace of color in an instant.
The person he loved most had died before his eyes, and at the hands of his most important comrade, the one he had entrusted with his other eye!
Utter grief, boundless fury, the despair of being mocked by fate...
All those extreme emotions erupted like a volcano in his heart, burning!
Hum!
An immense, chilling surge of Eye Power suddenly descended!
The pattern in Obito's Sharingan, previously only a two-tomoe Sharingan, began spinning rapidly, changing shape and connecting...
Until it finally became a completely new, intricate pattern resembling a shuriken!
At that moment, the Mangekyō Sharingan awakened through the extremes of "love" and "loss"!
