As Terumi ran through the shaking forest towards his new prey, many smaller beasts were scrambling around in fear.
Terumi saw their panicked state and wondered what could cause so much distress.
'This didn't happen during the last month. What's going on?'
Keeping up his fast-paced sprint through the forest, soon he arrived near the base of the volcano and heard a terrifying roar.
"ROARRR!"
It came from right behind him as Terumi panicked and hurriedly dodged to the side.
"What the!?"
What Terumi saw after twisting his body, narrowly dodging something grazed past him, was a large red wyvern. It landed right in front of a pile of magma rocks, chomping down on it like a light snack.
"A dragon? No, a wyvern. It's feeding on the molten lava and magma rocks from the volcano. What manner of creature is this?"
As Terumi cautiously eyed the fifteen-meter tall wyvern with a wingspan of twenty meters, he tried to gauge its threat.
The wyvern noticed the human standing not too far away from it and roared in annoyance.
"Roarr!"
"Shit!"
The wyvern breathed fire at high speeds directly at Terumi, wanting to burn him to a crisp.
Terumi maneuvered himself out of the line of fire, but the wyvern traced him with his breath.
"Alright fine."
Terumi leaped and span his body rapidly.
'Breath of Water, Sixth Form.'
"Nijire Uzu! (Whirlpool)"
Terumi's attack created a large whirlpool of air, sucking the fire breath in and diverting it towards the sky.
The wyvern saw this and roared once again in anger. Leaping off the ground, it started flapping its enormous wingspan quickly, creating sharp hurricane-force winds threatening to slice Terumi to pieces.
The winds easily slice through Terumi's previous attack and started causing small cuts all over his body.
Terumi gritted his teeth, using Asahi to defend as much as possible.
'Switching breaths is gonna be a pain for me later but let's do it.'
Terumi grasped Asahi tightly with his hand, summoning a little Haki to add effectiveness to his move.
'Breath of Sun, Forth Form.'
"Shakkotsu En'yo! (Burning Bones, Summer Sun)"
Terumi twisted and curved his slash in a forward circular motion, creating a barrier of circular flames directly in front of him, and blocking the wyvern's vision of him. Using the momentary respite, Terumi sheathed Asahi and prepared his next attack.
'If I'm gonna do it, might as well do it all the way.'
Terumi's thighs and quads muscles bulged largely as he pumped all his power into them.
'Breath of Thunder, First Form.'
"Hekireki Issen: Shinsoku! (Thunderclap and Flash: Godspeed)"
Terumi drew his sword and disappeared in a flash of light and thunder aimed directly at the wyvern's neck.
'Take this!'
Seemingly before the wyvern could even react, Terumi flashed to right in front of its neck, with his sword a mere inches away from taking its head off. However, what Terumi didn't realize was that the wyvern was already in the motion of flapping its wings, causing it to fly directly straight up at blinding speeds, resulting in Terumi's attack missing.
Terumi landed on the ground and looked up to the sky, shocked by what he just witnessed.
"How did it dodge? That was my fastest attack!"
The wyvern floated in the air radiating with a feeling of superiority as if it wasn't concerned at all.
"Roarr!"
With a roar, it started the motion of flapping its wings once more and then disappeared from Terumi's vision.
"So fast!?"
Feeling intense danger coming from his left side, Terumi ducked. As soon as he did, a sharp current of air passed right by him, bisecting several trees in half.
Seeing that its attack missed, the unseen wyvern started circling Terumi at high speeds, using the forest as cover.
"This is not good, I'm on its home turf. I need to clear away some of these trees or else I'll never be able to find it."
Terumi gripped Asahi tightly with one hand, his arm muscles bulging.
'Breath of Moon, Fifth Form.'
"Geppaku Saika! (Moon Spirit Calamitous Eddy)"
Sending waves of curved crescent slashes in all directions, Terumi cleared away all of the surrounding trees in a twenty-meter radius.
At that moment, Terumi's danger sense kicked in again, telling him to leap.
He leaped as high as he could, and as soon as he did, a vortex of winds passed right under him, shredding the ground where he once stood.
Looking around, Terumi saw traces of wind trails flying about in the trees but still could not locate the wyvern circling him around at high speeds.
Seeing this, Terumi swiftly sent multiple flying slashes where he sensed the wyvern's presence, but his attack did not find its mark.
"This is pointless, it's too fast. I'm wasting my energy clearing all these trees."
Terumi flipped his body in mid-air and landed on the ground, trying to sense where the next attack will come from.
After seeing that its previous attack had failed, the wyvern also cautiously hid, waiting for the next moment to strike.
"Okay, I haven't tried this before, but in theory, I know how it works."
Terumi ripped off his shirt to expose his bare chest and closed his eyes.
'Breath of Beast, Seventh Form: Kukan Shikikaku. (Spatial Awareness)'
Feeling the vibrations in the air, the whole world around Terumi started fading to black, as he sensed the subtle movement with his skin.
At the moment, backed by his keen danger sense, he built a spatial map in his mind, tracking the wyvern hidden on a branch of a nearby large tree.
'There! Breath of Thunder, Fifth Form.'
"Netsu Kairai! (Heat Lightning)"
Terumi sent a long-ranged lightning-speed slash at the Wyvern's location. Although caught by surprise, the Wyvern was still able to narrowly move its body to dodge the attack, but it left a graze across its chest, drawing blood.
"Roarr!!"
The beast roared in anger and started circling Terumi at high speeds once more, sending wave after wave of sharp wind attacks from all directions.
Switching back to his spatial awareness and feeling the vibrations in the air on his skin, Terumi dodged all of the attacks as they came close.
'I won't be able to last forever with the constant switching. I need to find a way to attack while tracking the wyvern moving at high speeds. Inosuke's spatial awareness is similar to observation Haki, but it only lets me sense the attack as it comes, it doesn't let me sense the opponent's intent.'
Terumi grimaced while moving his body rapidly, doing his best not to fall under the storm of wind blades.
'Also, I have to maintain this breath in order for it to be active, so I can't attack and sense the air at the same time. I have to learn how to do both. My guess is that the wyvern has advanced air sense as well, as it is a flying creature. It's using it to dodge my attacks the moment it senses the change in the air. If it can do it, so can I. Its hide is not that thick, my previous attack didn't have any Haki and it was from long range, but still managed to draw blood. If I can get one good attack in, I can take it down.'
Determined to find a way to conquer this challenge, a fire lit in Terumi's soul. His Haoshoku Haki leaked as he then sheathed Asahi.
'Time to gamble.'
Terumi stopped his spatial awareness, and took an iai stance, switching over to his thunder breathing.
As soon as he did, he tried his best to sense the incoming attacks without his breath of beasts.
Terumi gripped Asahi's handle tightly, twisting his body to avoid all the attacks he can, but quickly started getting overwhelmed, numerous cuts found their way into his bare chest.
Terumi's brow furrowed, focusing his mind on the task at hand, ignoring the blood leaking out from his wounds and mouth.
At that moment, he sensed something coming directly at his neck from behind. He inched his head to the side, narrowly dodging the attack.
Then again, from his back left. Back right. Front, angled down.
Terumi could feel the subtle vibrations in the air as he started maneuvering more easily, taking fewer and fewer cuts.
Then, time slowed down. Terumi saw it clearly in his mind. Wave after wave of disturbances in the air, and from its source, a faint silhouette of the flying beast.
Terumi unsheathed his sword at lightning speed.
'Forth Form: Enrai (Distant Thunder)'
Terumi weaved his slashes into several chaotic slashes, surrounding the wyvern and stopping it momentarily in its tracks.
'First Form.'
Terumi's body started to heat up, his blood started pumping at hyperspeed, his bpm reaching well over 200. The mark on his forehead grew and wrapped itself around his left eye. His Haki started to rapidly wrap around Asahi.
"Hekireki Issen: Shinsoku!"
Terumi disappeared in a flash of light, the sound of his thunderous step didn't even register to the wyvern until Terumi was right in front of him.
"Die!"
Zzzzz CRACKLE!
With the sound of a thunderclap, the wyvern's head was cleanly separated from its body.
Terumi front flipped in the air, landing on the ground, breathing heavily.
"Haa, haa, haa."
Terumi looked back, to see the sight of the wyvern's body, falling hard onto the ground.
Thud.
"That's two down. Haa, haa."
Terumi fell flat on the ground, muscles aching, body bleeding, but feeling satisfied with his growth.
