Without Sword Intent Mode, he truly wouldn't be able to control such a powerful Ultimate Form.
This was like a temporary trial card, an Ultimate Susanoo trial card that could only be used in this world!
Such powerful, pure energy placed before him was astonishing, even if it was just an intangible mass of energy.
Tohru stared blankly at the Susanoo standing in front of her. She had seen this state during their arm-wrestling match, but never this powerful.
'Did he go easy on me to spare my pride?' Tohru couldn't help but think.
But her heart was filled with warmth, 'Indeed, I hadn't misjudged him. Yusei really knew how to consider others' feelings, my feelings.'
Pushing herself up, Tohru stood beside Yusei, shoulder to shoulder with him, facing her father.
"Is that so? If you hold that mindset, you will be defeated by me."
Zap!
Like a flash of lightning, all that remained in the dragon eyes of Tohru's father was a lightning-shaped humanoid figure beside Tohru, while the massive blue-white energy warrior had vanished.
Immediately after, a shadow that blotted out the sky descended upon him from above.
Boom!
A tremendous slash instantly landed on Tohru's father.
This attack, combining speed and power, was several times more intense than the previous one.
Tohru's father hadn't expected that massive form to possess such incredible speed.
Caught off guard, he was sent flying, crashing into a distant mountain peak and embedding himself deep within.
"Damn brat, that actually hurt! Accurately grasping the characteristics of lightning… fast speed and powerful force. Quite interesting."
The red dragon brushed away the rocks on his body and praised Yusei.
'Didn't even break the scales? No, he must have defended with his power at the last moment.'
Yusei looked at the completely unscathed dragon standing up, his heart sinking slightly.
For the other to react even at that speed showed just how difficult this dragon was to deal with.
'Then I'll use multiple slashes in high-speed mode, so he can't react.' Yusei thought to himself, simultaneously looking at Tohru.
"Tohru, cover me. Use ranged attacks to pressure your dad."
"Don't you need me to go help you?" Tohru asked worriedly.
"No need. His speed probably can't match mine."
"Alright then." Tohru felt a bit dejected but still followed Yusei's tactic.
She already knew Yusei was much stronger than her. Going over might not even be of much use.
"Finished discussing? If you want to make me yield, this level is not enough." The red dragon laughed heartily.
Yusei sneered, "Of course it's more than this."
As his voice fell, his figure vanished again, leaving behind a lightning afterimage.
Screech!
It was as if thousands of birds were crying.
Accompanying this sharp cry, Yusei's Susanoo displayed speed utterly incompatible with its huge body, leaving a trail of lightning in its wake.
'Here he comes!' Tohru's father thought, actively preparing his defense.
He constantly scanned his surroundings, trying to determine from which direction the attack would come. At such high speeds, he couldn't keep up.
Therefore, his strategy was to counterattack from his position, seizing the opportunity during the brief pause after the opponent's attack to strike back.
To execute this counterattack, he absolutely had to determine or detect where the attack was coming from.
'Not front, back, left, or right... then... from above?' Tohru's father suddenly looked up, only to find a long sword composed of lightning blades already descending, striking directly on his head.
Intense currents crashed against the barrier formed at the last moment, emitting a sizzling sound, yet they failed to harm Tohru's father protected beneath.
Yusei had no intention of staying after one strike. His figure vanished again, continuously attacking Tohru's father from all directions.
Frenzied electric currents instantly swept through the area, charring the mountain forest soil black, with sparks crackling and flashing incessantly.
But for Tohru's father, completely enveloped within, these attacks were utterly useless.
Yusei retreated under the cover of Tohru's artillery fire. He fell back to a safe distance, his expression somewhat grim.
The previous attacks weren't just high-speed multiple slashes, they were focused attacks.
Simply put, he concentrated multiple attacks on a single point, trying to break through the defense.
Just now, while consuming a massive amount of lightning power, Yusei had unleashed dozens of slashes in less than ten seconds.
'Dozens of strikes concentrated on one point, and that barrier was still completely intact. It was as hard as a turtle's shell.'
Now, as the battle duration increased, what was being consumed wasn't just lightning power, but also Ocular Power.
Even the Eternal Mangekyo doesn't have infinite Ocular Power… it just can continuously recover.
But the current consumption was clearly starting to exceed that recovery limit.
Feeling the swelling pain in his eyes, Yusei gritted his teeth again and drew a large wave of lightning into his body, replenishing his energy.
Watching all this, Tohru's father dispelled his barrier and looked calmly at Yusei.
"Brat, you can't even break a barrier of this level? What will you use to protect Tohru then?"
"Old man, you're cheating, aren't you? That barrier is already at a level that shouldn't be breakable in this world."
Yusei retorted without hesitation. He was confident in the attack power of the Susanoo in its Ultimate State, so he was convinced Tohru's father was cheating.
"I would go easy on you and Tohru as juniors, but would an enemy? You are still far from ready. If you can't even break my defense now, how will you protect Tohru? This barrier is only at half the strength of my full power."
Tohru's father spoke indifferently. He just stood there, not moving, as if waiting for Yusei to break his defense.
In truth, after seeing Yusei's potential, his initial resolve to take Tohru away had slightly wavered.
From initially fighting the two of them, he now wanted to test just how much of a surprise this human could give him.
A barrier with half its defensive power. This was the test he set for Yusei.
In his view, this was merely the level of a world-class powerhouse. If Yusei couldn't even reach this level, then talking about protecting Tohru was pointless.
If Yusei himself, in this world, encountered a formidable foe, even surviving would be a question.
