The appearance of the Sharingan replenished a lot of Chakra for Obito. However, due to Might Guy and Berkeley being entangled in combat, Obito didn't use Fire Release to attack, but instead concentrated his breathing, drew a Kunai, and greeted the foe.
Although Berkeley was prepared to first handle the strongest, Might Guy, he also kept part of his attention on Obito's side to prevent a sneak attack, as his strength was much greater than Might Guy's. Even so, he could suppress Might Guy in battle.
"Sharingan, it turns out you're not ninjas from Hidden Sand, but Konoha's ninja." Berkeley, upon kicking Might Guy away, revealed a surprised expression.
Immediately, Berkeley regretfully sighed, "What a pity, it would have been better if it were the Byakugan."
Hidden Cloud isn't envious of the Sharingan, as only the Uchiha can use it powerfully, while the Byakugan is different. The Byakugan's strength in combat doesn't match its strategic value.
Perception Ninjas are highly valued in any Ninja Village. One needs perception ability to learn Perception Ninjutsu, and the Byakugan is beyond perception, directly offering wide-range vision. In war, it's like having a cheat of transparency.
If Berkeley could bring the Byakugan back to his village, even just one, he wouldn't have to worry for the rest of his life; it would be much more of a merit than killing a Jonin from an enemy village.
"Come and try if you have the ability," Obito taunted.
"As you wish."
Lightning exploded from Berkeley's leg as he charged towards Obito at high speed.
Before activating his Sharingan, Obito couldn't see Berkeley who was using the Lighting Instant Body technique, only faintly glimpsing a shadow amidst the lightning flashes.
But once he activated the Two-Tomoe Sharingan, Obito could clearly see Berkeley rushing towards him, even noticing the dust clinging to Berkeley.
"So this is the power of the Sharingan. No wonder Shisui could easily defeat Kakashi after using it. If it were now, I could undoubtedly defeat Kakashi," Obito couldn't help but think.
However, Obito didn't become careless because he had previously defeated Hyuga Kamon, who possessed the Byakugan, without having the Sharingan active.
Sometimes it's not enough to see something; you may not be able to catch or dodge it.
"Kakashi, today I'll show you what real Breathing Technique is!"
Just as Kakashi blocked the sword for him and got hurt, Obito could feel his breathing concentrating like never before. His heart ignited; he wanted to avenge Kakashi, to defeat the enemy with flames.
"Breath of Flame, Full Concentration Breathing!"
With his Double Tomoe Sharingan closely watching, Obito inhaled large amounts of oxygen, enhancing his physical abilities and nature transformation speed.
Whoosh!
Berkeley appeared in front of Obito, swiftly slashing down at his chest with a sword.
But surprisingly, Obito easily sidestepped and counter-attacked with a Kunai.
Clang!
Berkeley quickly changed his move to block the incoming Kunai.
Clank! Clank!!
The two engaged in a rapid exchange of blows. Although Obito's Kunai skills weren't particularly formidable, under the dynamic vision of the Sharingan, he managed to withstand Berkeley's attack.
"As expected of the Uchiha Clan's Sharingan, the strength increased so significantly all of a sudden," Berkeley was somewhat stunned by Obito's growth in strength.
"Leaf Strong Whirlwind!"
Since they were already exposed, Might Guy simply let loose and shouted, kicking heavily at Berkeley.
This made Berkeley uncomfortable. Facing Might Guy or Obito individually he could easily handle, but dealing with both at once was troublesome.
Might Guy was fast, powerful, and agile, while Obito had keen insight to see through his moves and also mastered a Fire Release technique that needed no hand seals.
The most important thing was, his state was gradually declining. Berkeley's Chakra wasn't abundant, even considered low compared to his combat abilities.
Berkeley wanted to handle Might Guy first, but Obito could see through his moves, each time directly warning Might Guy, telling him to be careful, while also harassing Berkeley with attacks, rendering his offense ineffective.
Tackling Obito first was even more challenging due to the Sharingan's strong insight making it hard to launch a successful surprise, plus Guy's quick support.
Berkeley would rather deal with two Obitos or two Might Guys than one of each; these two together, with one's insight and the other's combat prowess, transformed the battle remarkably.
Observing from the side, Kakashi was also amazed by their combined strength; they weren't just any random ninjas, but Jonin capable of leading teams on critical missions!
And Obito and Might Guy? They weren't even Official Ninjas; just small-time Intern Ninjas, not even graduates yet.
"I've been completely surpassed; they're the true geniuses…" Kakashi thought to himself.
Compared to him, who graduated early, the current Might Guy and Obito more accurately fit the definition of prodigies.
Once, he and Obito teamed up and were nearly powerless against Berkeley, yet now, Might Guy and the Sharingan-activated Obito could suppress Berkeley together.
"Thunder Shock Sword!"
Sensing the unfavorable situation, Berkeley decided to go all out, unreservedly using his Chakra on various Nin-Taijutsu techniques, launching a frenzied counterattack.
A Jonin fighting desperately is terrifying; Obito and Might Guy both sustained some injuries, though they were mere scratches without much impact.
"Fire Release: Impatiens Claw Red!"
Taking advantage of Berkeley's intense counterattack just starting, Obito swiftly flung four flame-imbued shuriken towards Berkeley.
