Jiraiya thought that the current idle Tsunade would have no interest in teaching a disciple, but unexpectedly Nohara Rin had such a connection with Tsunade.
He realized that if he let Obito sign with Mount Myoboku, and Kakashi made an effort at the Ryuchi Cave, they could really become the new Sannin.
"Bursting Fist!"
Nohara Rin wanted to act as bait to create an opportunity for Obito and Kakashi, rapidly gathering a large amount of Chakra into her fist and charged towards Jiraiya.
Bam!!
A huge explosion resounded, and the ground Jiraiya had just been standing on shattered.
Jiraiya couldn't help but break into a cold sweat at this sight, this was not something to be inherited.
Rin's display of Monster Strength Power reminded him of some unpleasant memories; that time he was really almost beaten to death.
"Opportunity!" Obito seized the moment Jiraiya was distracted, bursting with Chakra as he charged forth.
"Fire Release: Leaf Whirlwind!"
Obito's right foot, carrying compressed flames of a deep hue, aimed for Jiraiya's head.
"Lion Mane Jutsu!"
Jiraiya calmly formed hand seals, enhancing his long white hair with Chakra, which then grouped together to capture Obito's body.
Just as Jiraiya was about to slam Obito into the ground, Kakashi made his move again.
He simultaneously activated the Transparent World and Breath of Thunder Chakra Mode, his body reaching its peak state, swiftly slashing at Jiraiya. Although he did not hit Jiraiya, he managed to cut off a portion of the white hair, rescuing Obito.
Having been saved, Obito immediately spat out Fire Release at the nearby Jiraiya. In the Breath of Flame Chakra Mode, he could release any Fire Release without needing hand seals.
"Fire Release: Great Fireball Jutsu!"
Obito's choice remained the Great Fireball, because he was so close to Jiraiya that Jiraiya could hardly dodge.
This way, the drawbacks of the Great Fireball being hard to hit no longer existed, leaving only its small consumption and great power.
"Ninpo: Needle Jizo!"
Jiraiya increased the enhancement on his hair, changing his move from offensive to defensive, letting the lengthened and hardened hair completely wrap around his body.
Boom!!
Firelight engulfed Jiraiya, and the dissipating Fire Attribute Chakra and thick smoke obscured the scene within.
"Could something have happened?" Obito mumbled to himself.
Though he thought Jiraiya deserved a beating, Jiraiya was Minato-sensei's teacher, so a light beating would suffice, injuring him wouldn't be necessary.
Kakashi gathered Chakra, waiting for the next opportunity.
The opponent was the legendary Sannin, Kakashi wasn't so arrogant as to think these small tactics could make him fall.
"You really gave me quite a pleasant surprise." Along with Jiraiya's hearty laughter, the smoke cleared, revealing his figure.
Obito's eyes widened, Jiraiya was uninjured, only having some soot from the explosions.
Jiraiya brushed off the dust from his body; Kakashi and his team's strength was beyond his expectations, so he prepared to get a bit more serious.
"Shadow Clone Jutsu!"
Jiraiya formed hand seals and split into two Shadow Clones, with one charging at Obito and the other attacking Nohara Rin.
"Fire Release: Flame Charge!"
Without any fear, Obito ignited his entire body with flames and collided with the approaching Jiraiya's Shadow Clone.
Although the Shadow Clone was a solid clone, it was particularly fragile; as long as it was hit by his flames, it would surely disappear.
"Water Wave Hand!"
Jiraiya's Shadow Clone extended a hand, releasing a large amount of water that rushed towards Obito, extinguishing the roaring flames on Obito's body instantly, soaking him completely.
"Ptui!"
Katsuyu gathered a mouthful of acid and spat it at the Jiraiya Shadow Clone attacking Nohara Rin.
Familiar with Katsuyu's attacks, Jiraiya anticipated this, and dodged sideways, forming hand seals to fling Wind Blade at Rin.
Rin used Water Array Wall for defense, but the water wall was cut by the Wind Blade, nearly injuring her.
Kakashi, who had been contending with Jiraiya's main body, narrowed his eyes in thought.
The Transparent World allowed him to observe the battle between Obito and Rin while dodging Jiraiya's attacks.
Kakashi noticed that Jiraiya was an all-around ninja akin to Mokgetsu, seemingly mastering various types of ninjutsu without apparent weaknesses.
"Continuing to drag on is just a waste of time; we must attack together," Kakashi decided internally.
Neither theoretically nor practically could they defeat Jiraiya now.
But as a ninja, even in a simulated battle, Kakashi must find that single opportunity that might lead them to victory.
He was currently the strongest ninja in Minato's squad, his attacks were the most powerful and fastest.
"Lightning Release: Pseudo-Darkness!"
Kakashi unleashed an immensely powerful Thunder Spear to push Jiraiya back, signaling Obito and Rin with a glance.
As longtime teammates, as long as the command wasn't too complicated, a mere glance could suffice for communication.
Faced with Kakashi's demand, Obito felt a bit disgruntled, as it was for Kakashi that he got beaten and dragged Kakashi into this battle, and now he even had to help create an opening for Kakashi.
Of course, Obito followed Kakashi's instructions to act.
If things went according to Kakashi's direction and Kakashi didn't succeed, he could then harshly criticize Kakashi, showing Rin Kakashi's bad nature.
Obito deactivated his Sharingan, channeling all his Chakra into activating Breath of Flame Chakra Mode, making his attacks more aggressive, and relentlessly releasing Fire Releases against Jiraiya's Shadow Clones as if not consuming Chakra.
Rin did all she could to entangle Jiraiya's Shadow Clone as well.
Unlike Obito, her task was merely to hold off a Shadow Clone.
After all, expecting more would be unrealistic, and the medic shouldn't be burdened with too much.
Kakashi, using Lighting Attribute Chakra to vitalize his body, sped towards Jiraiya's Shadow Clone on Obito's side, as if he planned to team up with Obito to eliminate the Shadow Clone first.
Jiraiya's main body, seeing this, followed at his own pace.
His experienced eye had already caught on to part of the plan, yet since this was training, Jiraiya had to make accommodations.
In a real battle, the first thing Jiraiya would do is use the Summoning Technique to call forth Gamabunta.
With Gamabunta's strength, dealing with Kakashi and his team would be more than sufficient.
"Fire Release: Flame Emperor!"
At this moment, Obito suddenly burst forth, channeling all of his Chakra to summon Fire Release, forming a massive fireball over ten meters wide in his palm.
Kakashi's plan was quite simple: create the illusion of tackling the Shadow Clone, then use the properties of Obito's Breath of Flame Chakra Mode to unleash a large-scale Fire Release, creating chances for Kakashi.
Under the immense flames of Flame Emperor, Obito seemed insignificant, yet with such a massive fireball, the attack range was undoubtedly wide.
As the fireball was launched, Jiraiya felt as if his skin dried out a bit.
"Earth Release: Earth Flow Wall!"
"Water Release: Water Prison Jutsu!"
One of Jiraiya's Shadow Clones used Earth Flow Wall, while his main body raised a water barrier.
Theoretically, the Earth Flow Wall was enough to block the attack; the water barrier was to avoid getting covered in soot.
Boom!!
The colossal crash resounded as the thick and tall earth wall suffered severe damage but was not utterly destroyed.
"One Flash: Divine Speed!" With the Transparent World activated, Kakashi had been closely monitoring the situation.
Once the most dangerous explosion shockwave faded, Kakashi immediately concentrated all his energy into a flash of lightning, charging forward.
Although Thoughtless Slash was stronger, at this moment he didn't have enough Chakra left to execute it.
Currently, Kakashi could only use Thoughtless Slash at full capabilities.
Sensing the imminent lightning charge, Jiraiya was slightly surprised yet quickly reacted due to his extensive experience.
"Summoning Technique!"
A wall of red flesh appeared out of thin air, enveloping Jiraiya before the lightning reached him.
PS: I've prepared a bit of an outline today, and now that my eyes have mostly recovered, updates will resume at 8k tomorrow.
