Obito deactivated his Hollowfication and charged towards Senga.
Senga smiled slightly, then kicked Obito in the stomach, sending him flying backward.
The terrifying power nearly Obito unconscious on the spot; had it not been for the boost from Hashirama Cells, the battle would have ended with that single blow.
Staggering to his feet, Obito activated his Hollowfication ability again, which finally put him at ease.
Recalling what had just happened, Obito was still shaken. His physical strength was definitely not weak, but he had been defeated so completely by Senga!
What exactly did Senga do all these years? Why did she become so strong?
Senga looked at Obito with a half-smile and asked,
"Finally couldn't hold back anymore? The Uchiha Madara I know wouldn't be this agitated over a woman's tombstone."
Obito was silent for a moment before speaking.
How did you know who I am?
"Hehe, I know more than just that."
"What else do you know!?"
"Hmm... for example, Infinite Tsukuyomi?"
"What!?"
Obito's expression beneath the mask instantly turned terrified. This was arguably his biggest secret, Senga actually knew even that?!
Suddenly, as if he had thought of something, he called out to Senga.
"Could it be that your Mangekyō Sharingan has Awakening Future Sight Dojutsu!?"
The secret of Infinite Tsukuyomi is known only to him, Madara, and Zetsu. No one else could possibly know it. In Obito's view, the only explanation is Senga's Mangekyo Dojutsu.
Senga was taken aback for a moment, and inwardly admired Obito's thought process, because this explanation was actually quite reasonable.
Some fan works also describe Fugaku Uchiha's Mangekyo Dojutsu as Future Sight, and it is precisely because Fugaku saw the future that he gladly faced death.
However, Obito never imagined that Senga was a transmigrator from Blue Star.
Senga shook his head and chuckled, then activated his Mangekyō Sharingan.
Upon seeing Senga's Mangekyo, Obito immediately concluded that it must be the legendary Eternal Mangekyo Sharingan, as the Pupil Power emanating from it was far beyond what ordinary Mangekyo could achieve.
Just thinking about Senga's "Dojutsu," Obito's expression darkened.
What else did you see?
"I saw you and Lin together."
Obito narrowed his eyes. Did this mean he was dead?
He naturally didn't believe Senga's words entirely, but he hoped they were true. Even in the afterlife, as long as he could be with Rin, he would die without regrets.
Obito shook his head. The afterlife was still too unreal for him. His only pursuit now was to create a world with only Rin using the Infinite Tsukuyomi!
Now, Senga, who knows his secret, is the biggest obstacle, and he must deal with this.
With this thought in mind, Obito's gaze hardened. He glanced at Senga, and then his body was sucked into the Kamui Space.
Senga stood there with his arms crossed. Suddenly, the space behind him distorted, Obito appeared from within, grabbing Senga's shoulder.
"We succeeded!"
Space distorted again, sucking Senga in.
Senga entered the Kamui Space. He looked around; the environment was dim, with only a few protruding, rock-like objects, and nothing else.
This could be considered Kakashi and Obito's private space, except that Kakashi couldn't bring himself inside.
In the past, after Obito them into the Kamui Space, he would also follow them in. In a one-on-one situation, it would be difficult for anyone to be his match.
If the enemy is difficult to deal with, he will adopt the simplest and most brutal method: wear them down until they are exhausted.
Senga was one of the more difficult opponents, so he chose this method to trap Senga first, and then come in to reap the spoils once Senga was exhausted.
After all, Senga possesses a pair of Eternal Mangekyō Sharingan, and her Dojutsu even Future Sight. It would be good to switch to one and see what the future holds! Obito is practically drooling with envy!
However, Senga fears least is a war of attrition.
With his current physical condition, even if Obito dies of old age, he won't be worn down to death.
Moreover, entering the Kamui Space was intentional on Senga's part.
All he wanted was the coordinates of the Kamui Space.
After admiring the scenery in the Kamui Space for a while, Senga activated his Rinnegan and released Yomotsu Hirasaka.
A black hole appeared beneath Senga's feet. He lifted his leg and stepped into it, his body disappearing into the black hole.
Outside the Kamui Space, Obito was still gloating over how easily he had "dealt with" Senga. Before he could celebrate for long, Senga's voice came from behind him again.
"Hey, you're still here?"
"What!?"
Obito turned around abruptly and saw Senga's smiling face and those Twelve Tomoe Rinnegan.
Without having time to think about how Senga escaped, he immediately used Hollowfication.
Senga smiled, and a small black hole appeared in front of him. Then, he punched into it.
"Hmm!"
Obito groaned, his body curling up like a shrimp as he clutched his body and retreated, clearly having been attacked.
He struggled to lift his head and look at Senga, his eyes filled with disbelief.
"How is this possible!? You actually awakened the Rinnegan!?"
Senga didn't say anything, but punched the black hole a few more times. Eventually, Obito was lying on the ground.
Left with no other choice, he had to deactivate his Kamui, completely exposing his physical form to Senga.
Senga slowly approached Obito, bent down, and removed his mask.
Obito offered no resistance, allowing Senga to remove his mask. He suddenly laughed.
"Hahaha! I never expected you to possess these eyes. My defeat was not unjust!"
Obito could actually use Izanagi one more time, but that would only buy him some time. Now that his Kamui has been broken and he's facing off against a pair of Rinnegan, he has completely lost his will to fight.
As he laughed, tears welled up in Obito's eyes. He looked up at Rin's tombstone, his eyes filled with longing.
"What a pity, Lin, I couldn't complete that plan. I guess I'm still a loser..."
Then, he suddenly looked at Senga and shouted,
"What are you waiting for? Kill me now!"
Senga shook her head and said,
"Dying isn't that easy. You still have a few people to see before that."
"Who is it? Is that Kakashi? Hmph, that piece of trash, I have nothing to say to him!"
"Heh, he's not the only person you want to see."
Before Obito could even speak, Senga Door-Door Space and threw him inside.
