Chapter 159 - Who The Hell Do You Think I Am?  

As Sasuke and Itachi fight with Orochimaru, Kakashi notices the scratch mark on Obito's mask and comes up with a theory about the Jutsu he is using, so he says to his teammates "There's something I want to try, help me out" then Naruto, Kakashi, and Gai jump on B hand, and he throws them at Obito, first his Gai, who attacks Obito with his nunchakus, but Obito first let the attack pass through his body, then he grabs the other end of the nunchaku as starts absorbing it in his dimension, and at that moment, from behind Gai, Naruto appears and attacks with a Rasengan.

As Obito just finishes absorbing the nunchaku, he uses Kamuni to let the attack pass through once again, but all of the sudden Naruto's Rasengan disappears, and once they pass each other, Obito is hit by it on the shoulder forcing him to take some distance from his opponents, while Naruto yells "It was just like Kakashi-sensei said!" and Kakashi pointing at Obito says "Just like I thought... At first I thought he had two Jutsu, one for going transparent and another for taking an object out, but that isn't it... You only have one Jutsu!!".

Then Kakashi starts explaining how the Jutsu works and how the space that Obito uses is connected with the space he uses with Kamui, reaching that point Kakashi asks "Where did you get that eye!?" and Obito replies "Where you ask...? Hm... If I dare... Say, it was during the previous great war, the Battle of Kanabi Bridge... You participated in this war hailed as 'The Sharingan Hero'!".

Kakashi shocked only says "You're..." but is interrupted by Obito who starts rebuking Kakashi, who is starting to look almost pale as a shocking idea is taking over his mind about the true identity of Madara, but Naruto counters his argument and once again entering in Kurama Chakra Mode he attacks Obito, while Gai rouses Kakashi who was lost in thought "Kakashi!! Are you listening!!? We should attack as a diversion!! Let's join the battle!! I can imagine what's going through your mind right now, I'm thinking the same thing... But forget him! Now is not the time to be sentimental!! Your student Naruto has plunged into battle before your eyes!!".

At the same time, Obito slips through Naruto's attack and uses Kamui to throw out a volley of giant shuriken at him, but B uses his tails to catch some of them, while Naruto uses a Kurama head construct, and Obito jumps high and throws out a volley of black stakes hitting Gyuky's body and soon from it Chakra chain came out and stats wounding around his body as B yells "Naruto!! He's trying to bind my tailed beast powers!! Make sure you don't touch them!!".

Naruto hearing that makes a shadow clone, and while one Naruto rush toward Obito, the other moves to the side and prepares a Bijuudama, the one close to Obito attacks him with a Rasengan, but Obito notices that Kakashi is using the same trick again and releases a black stake to hit Naruto who disappears "So it was a clone..." and noticing Kakashi falling into the ground exhausted with blood coming out of his eye he adds "You struck too early with that... Kakashi... And now the Rasengan will miss as well, you've used Kamui in vain again".

At the same time, the other Naruto releases his Bijuudama, but Obito calmly uses Kamui to slip through it, but once in his dimension he finds the figure of Naruto waiting for him with his Rasengan ready and unable to escape he is hit in the face breaking his mask and at the same time forcing him out of his dimension, making him finally show his face to everyone, and seeing him Kakashi yells "You're... OBITO!!".

Meanwhile, back where the Kages are fighting, Shinigami high in the sky, is looking down at the heavily injured figures of his opponents, Mei is kneeling on the ground losing blood from a wound on the stomach, Gaara and Onoki both lie on the ground unable to move with many cuts all over their bodies, A lies in a crater with blood coming out of his mouth, and even worse he lost his right arm, it was disintegrated by Shinigami's Cero, the only ones still barely up were, Konan, Yahiko, and Jiraiya but their bodies were full of wounds, and behind them the powerless figure of Tsunade, who reverted to her original look a sign that she exhausted her Chakra completely and looks in despair at her opponent, who looks totally unfazed.

Jiraiya still holding on in his Sage Mode without moving his gaze away from Shinigami says "Konan! Yahiko! I'll try to hold on as much as possible... You two take Tsunade and escape toward the Medic Division, and warn everyone about this monster!" before they could refuse he continues "Listen! I feel he that is an even bigger threat than Madara! And even worse I think that Orochimaru became something similar to him! They have to know!".

Just as they were talking, Shinigami looks in the direction of Naruto's battlefield and says "This Chakra... It's is Kaguya's one! It seems that fool is about to free her... Good! This way I can deal with both at the same time... And this time her sons aren't here to save her!".

Then looking back at Jiraiya and the others he says "It seems that my playtime is almost over, you guys were a decent warm-up...", he raises his arm and points his finger at the group and starts gathering his violet Chakra in order to finish them off with a Cero, then without giving them a chance to escape he shoot it.

Jiraiya's pupils dilate as he is seeing in slow motion the concentrated blast of Chakra coming quickly toward them, and moving on instinct, Jiraiya hugs Tsunade and uses his body to protect her in hope of being able to save her, but before the Cero could reach them everyone hears a male voice that yells "Bakudō #81. Dankū (Splitting Void)", and a translucent barrier in the form of a large rectangular wall appears in front of Jiraiya's group.

The Cero hits the translucent barrier and explodes creating a big cloud of smoke that blocks Shinigami's sight, then from within the smoke, the voice is heard once again "Man! It took a while to come back... Jiraiya-san, Tsunade-san I'm sorry for being late, but now it's fine! Why? I'm her... Wait! Wrong catchphrase!".

And as the smoke clears, Shinigami's pupils shrink, as he sees the figure of a smiling young man with mid-length pink hair tied in a low ponytail and green eyes, wearing the iconic Shihakuso with a familiar white haori, on his waist a regular katana, it has a simple cross guard, with an open frame much like a four-pane window, a bronze guard, with lavender hilt-wrapping, and a white sheath.

Jiraiya and Tsunade open their eyes and see the figure of their savior and both yell "REN!", while Shinigami roars in disbelief "Who are you!!?" and Ren looks at Shinigami and says "Who the hell do you think I am!?... I'm the true Shinigami!!" then calmly walking forward he asks "So Arracar-san how does it feel falling from being the apex predator to the prey?".
