Sharingan
"Y-You… You have awakened the Sharingan?"
Danzo stood still, frozen in shock. There should be nothing in this place to awaken his Sharingan. The Uchiha clan needs strong emotions for the awakening of the Sharingan, and Obito has done nothing but train in this place.
Obito rubbed his nose while he smiled and said, "Yeah! I suddenly awakened it for some reason when I was training."
Danzo thought of possible ways Obito awakened his Sharingan. In the end, he ended up asking Obito.
"How did I awaken my Sharingan?" pondered Obito.
"What were you doing before it awakened?" asked Danzo.
"Well…"
*Flashback*
Obito POV
Why can't I learn this stupid jutsu?! I've already learned the other two fire styles and even one lightning. So what's up with this stupid jutsu?
"Arghhhh."
I sat down while making a mess out of my hair. The jutsu is extremely difficult and takes a huge amount of chakra. A single use makes me run out of chakra. The other ninjutsus aren't this difficult.
With a sigh, I looked up and saw the same plain multi-colored sky. I started to think of the others, Kakashi, Rin, and Ennozo. It has already been seven years and I haven't talked to anyone since. I wonder if Ennozo Kakashi is hard at training. Could they still be stronger than me?
I curled up with my knees meeting my face. It wasn't cold nor hot in this place, it was just depressing.
"Will I ever become Hokage?"
Flashback ends
"Hehehe, it was really depressing not seeing or talking to anyone for seven years, and I started questioning if I could ever become Hokage… When it reached another month of no progress on the jutsu, I got my answer… I wasn't gonna become Hokage at the rate of my progress. That's when I suddenly felt something weird about my eyes. The awakening of my Sharingan made me have hopes again hehehe," explained Obito, giving a thumbs up with his last sentence.
Danzo still looked shocked but then asked Obito, "Would you like to test out your new Sharingan?"
"Yes!"

The two were right across from each other, with their hands forming the seal of reconciliation. The first to move was Obito. He quickly ran towards Danzo, who had a calm smile on his face.
Reaching Danzo, Obito jumped and reverse kicked Danzo right in the face. However, he was quickly caught without any struggle. After getting caught by his leg, Obito used his core and tried to punch Danzo in the face.
It was then again caught by Danzo. However, this time, Obito's leg got out of Danzo's grip, which he quickly used the opportunity to jump up high and perform a jutsu.
"Fire Style: Phoenix Sage Flower Nail Crimson!"
Twelve shurikens covered in blazing hot fire raced towards Danzo, who still stood in the same spot. As the shurikens got closer, Danzo countered with his own jutsu,
"Wind Style: Violent Whirlwind!"
Danzo's mouth produced a powerful stream of wind and got rid of the shurikens coming his way. As Obito landed on the floor, Danzo dashed towards him. However, Obito's Sharingan quickly caught up with the speed, allowing him to dodge to the left.
With Danzo now in an awkward position, Obito took the opportunity and tried to kick Danzo's chin. Danzo responded by dodging the kick. Using his elbow, Danzo rammed his elbow into Obito's face after he tried to kick Danzo.
Now on the floor, Obito was stunned as his head hit the ground hard. Danzo stood over him and said, "Your Sharingan can keep up, but your body can't."
After calming down, Obito quickly used hand signs and used a lightning-style jutsu,
"Lightning Style: Spider Web!"
A blue spider web-like drawing was drawn on the floor, paralyzing Danzo for a couple of seconds as Obito got away. After the paralyzing lightning ceased, Danzo frowned and said, "You have a lot of ninjutsus, but that's it… Have you been slacking off on your other fundamentals?"
Obito sweated a bit and threw five shurikens at Danzo. Danzo, ready to deflect them all, was shocked when the shurikens hit each other and changed directions. However, the shurikens were still deflected by Danzo with ease.
'He has already mastered the shuriken jutsu of the Uchiha clan, impressive,' thought Danzo.
Obito looked at Danzo with sweat on his face. He had used almost all of his jutsus that he had fully mastered. All except one.
Obito formed hand seals as Danzo watched with amusement, as he recognized the seals.
"Fire Style: Great Fire Destruction!"
A massive stream of intense flames came out of Obito's mouth. The heat was so intense that Danzo could feel it even as he tried to run away from it, using a jutsu he saw from Boruto. After running for a couple of seconds, Danzo turned back and was met with a blazing hot pit that was made by Obito, with Obito still being in the same position while huffing.
Huff Huff
"H-How did you outrun my jutsu?" asked Obito.
Obito's vision began to wane as he had used too much chakra during the fight. Obito began to fall forward but was soon caught by someone. Obito looked up and saw Danzo smiling.
"I'll tell you… another time."
