{Somewhere outside of Amegakure}
{4:23 PM, 21st July 13 Yrs ANB}
{3rd Person POV}
Ren stared as Konan silently stood opposite him, he wasn't sure what was happening but had plodded along. Stepping foot outside of Amegakure felt freeing, the city felt like a caged box as every time he exposed his senses he could feel someone else lock onto his chakra signature.
By now Ren knew that there was another 'God' named Pain above Konan in the world's hierarchy. He took a deep breath and focused on the adversary before him for the moment, "What are we doing here?" Ren asked.
"We are here for your combat evaluation, if you want to join Amegakure's ranks, you have to prove that you would not endanger the life of fellow shinobi outside of Ame," Konan spoke, her eyes still cold.
"Uh alright, what do you want me to do?" Ren asked.
"Fight me with everything you have got." The instruction was clear as day and once saw that her face was set in an emotionless mask he nodded. He pulled out his sword from his sheath and dashed toward her.
Chakra flew throughout his body as he augmented his muscles and increased his grip. His body flickered a few times as he faked his intent but Konan seemed unfazed. The slash was a normal slash in the beginning, but just before it reached Konan, Ren applied wind nature chakra to the edge of his blade increasing its length and sharpness.
'Chakra Flow'
~Flutter~
Instead of Konan bursting into blood and muscles or even a cloud of smoke from a substitution jutsu, her right arm burst into a bundle of paper. His senses tingled as he let go of his left hand from the sword and formed the handseal for the body flicker.
~Boom~
A powerful explosion ripped through the ground but Ren could see that not all of the explosive tags had erupted in this explosion. He dodged backward again as a hail of paper shuriken emerged from his right side, the advantage of being a sensor was that he was able to lock onto Konan's chakra signature so he wasn't caught off guard by this surprise attack.
The disadvantage of that was that because he was locked onto her chakra signature she was also aware of his position at all times. So he spent the next several minutes dodging as he revolved around Konan who seemed content with watching him plan his next move.
'She was fast and nimble, her ranged advantage is too much but since she is a sensor it won't matter if I even obscure her vision.' Ren thought, he sheathed his sword and held the tiger seal.
Tiger
'Fire Release: Great Fireball Jutsu'
His vision slowed down momentarily as he aimed his jutsu at her, his passive perks were one of the advantages that were unique to him. Konan remained unfazed and unmoving as her chakra signature remained in place. Ren had controlled the fireball so it was slow-moving as he pumped it full of chakra to maximize the impact of the jutsu.
Bird
'Wind Release: Great Breakthrough'
Ren compressed the wind jutsu as much as possible as he aimed it at the core of the fire jutsu that was about to reach Konan. The Wind jutsu was faster than the Fire jutsu and because of his perk Dead-eye he was able to perfectly capture the moment right before the Fire jutsu was about 4m away from Konan.
As the two Jutsu flew by, he pulled out his sword again and he focused on her chakra signature making sure that she didn't use any substitution jutsu or some other tricks. Konan had a different concept of fighting than Ren, she liked to observe her opponent and wait for the perfect moment to strike. The way in which Ren was still preparing a jutsu when a fire jutsu was moving toward her caught her attention.
She noticed that the fire jutsu was slower than normal, she had fought against countless Konoha shinobi and they seemed keen on using this technique. So she was aware that this jutsu could be a lot faster. That simply means that either this jutsu was a distraction or Ren had some plan involving it. Her instinct was to curb that plan as with a wave of her hands, her clothes broke into pieces of paper and smothered the fire jutsu easily.
The Great Breakthrough was a pressurized wind tunnel so it blasted apart her paper and came at her a little slower, a second later she simply soared above Ren's attack as two wings appeared behind her back.
Ren stared at her form as she stared at him with a stoic look, the two wings gave her a kind of maneuverability that she could maintain her ranged advantage for however long she wanted. And since her paper shuriken could shred through his ranged jutsu this fight would be at a stalemate. Ren moved into a defensive stance as he stared at Konan.
The stillness lasted for a second before a flap of wings, she was heading straight for him. Ren knew that he wouldn't have a second chance, she was cautious in her approach but as she came closer to Ren, he knew what he had to do.
'Fucking S-rank, and their monstrous stats...' Ren thought as he waited, although it looked like an eternity, he was focused on Konan's charge. Her speed was considerably slower under his enhanced focus but he still wasn't able to see all of her movements. When she was within 5m of him, he focused on the Gate of Opening.
His stance tightened as Konan's charge stilled, her momentum though pushed her a meter closer and that was all Ren needed. She could feel a massive surge of chakra erupt from Ren and her eyes widened as he flickered, for just a second his movements surpassed what he had shown as a gleaming sword was almost cutting into her shoulder. The biting cold of the sword haunted her arm for barely a second before Ren's sword cut through her entire upper body.
'Fuck,' Ren cursed, he flickered away in panic as the biggest explosion he had seen brightened the sky. His ears rang as he realized that he had lost track of Konan's chakra signature and he could not feel it anymore.
Ram
The Ram seal helped him increase his senses but no matter how much he tried he could not sense where she was. After a moment the dust settled and just as Ren walked forward to see if she was alive. He sensed her appear behind him, it was eerily similar to Obito's teleportation, one minute she wasn't there and the next second she was. Her speed was still slower than Obito's as he was easily able to dodge her attack.
He was feeling a little sluggish as he looked at the notification in front of him.

The damage done was minimal as he had barely used the first gate for a second, the prospect excited him though, if he could get away with stunts like these then the Eight Gates is a godlike technique.
He looked back at Konan's figure, particularly at her right shoulder, there was no damage to her clothes and she still stood impassively looking at him. He was sure that he had encountered a familiar resistance of tearing through muscles but maybe he was wrong.
'She is made of paper anyway how do I even get past her technique...' Ren thought.
"That's enough, come back to the hospital tomorrow, you'll be assigned the rank of Jonin," Konan spoke as her body disintegrated into small butterflies. Her chakra signature vanished and Ren realized why he wasn't able to sense her before. The amount of chakra in an individual butterfly was enough to fly past his radar.
'She's almost an invincible infiltration specialist.' Ren thought as he gulped. The amount of damage she could do to any shinobi nation was frightening to imagine.
'I need to start weight training again...' Ren thought.

AN - Konan was shown as calculative and having a strong perception in the show, I'm gonna build her character in that direction.
