Nen ability

It's been two years since then, and I have learned all of the advanced Nen techniques, bar Shu, which is useless to me as I don't use weapons.

I can last up to 150 minutes using Ren and my En extends to about 10 meters and can last for over 30 minutes.

He had been training his Transmutation, Conjuration, and Enhancement abilities in order to create his Nen ability.

Name: Hellfire Rose

Ability: User can Conjure a rose made of hellfire that releases an immense amount of heat; if an enemy is struck, it causes extreme amounts of pain. Each minute, another rose is created, increasing the heat and pain over time. The ability also scales in power by a factor of 1.5 and strengthens the user by a factor of 1.2. The user can choose to stop conjuring additional roses at any point.

Conditions: User must feel half the pain that is dealt to the enemy using Hellfire Rose.

The user must have endured more pain and suffering than his enemy has experienced throughout his entire life.

User has to actively control the Hellfire to attack; otherwise, it just stands still and releases heat.

Hellfire Rose can only be Conjured inside the user's En

If the user has this ability activated and exhausts all of their Nen, it will cause them excruciating pain, burning their body and killing them within seconds.

The conditions may seem terrible, but when you consider the fact that Gyro has experienced 3,000 years of suffering, it's impossible to feel any more pain than he does.

Having to experience half the pain the enemy feels might be horrible for the average person, but for Gyro, it would be pretty nostalgic for him.

Exhausting his nen by using Hellfire Rose would mean a death sentence anyway since his nen wouldn't reach such an extent unless he was in danger of dying.

He had been fighting in Heaven's arena for the past two years, fighting once every three months. That meant, so far, he had fought nine battles and won them all.

This time he would face a strong opponent who would likely require him to use his new Nen ability.

'The battle is tomorrow, so I should get some rest.'

The next day, Gyro can be seen standing in front of a muscular giant.

'Zanwel, an extremely powerful enhancer, will be a formidable foe.'

"On the left we have Zanwel the Giant, with 9 wins and 0 losses. Zanwel has never fallen down against an enemy once." The announcer excitedly says

"On the left we have 10-year old Gyro, who also has 9 wins and 0 losses. Can a 10-year old defeat Zanwel the Giant?" The annoying announcer says

Staring at Zanwel, I get ready to activate my Nen ability, Hellfire Rose.

"3, 2, 1, Go!"

I immediately activated Hellfire Rose using In to hide it from the crowd, which rapidly heated the room.

The crowd looked around in shock, after all they were not nen users and could not see objects conjured with nen.

"What just happened? It's boiling hot!" A viewer questions

"No idea mate, but I ain't missing this match for nothing." Another fan responds.

He could tell that the technicians had turned up the air conditioning, since it would have been much hotter otherwise.

"What this flower, You use Nen. Good Nen" Andre the Giant says.

'Is this guy fucking stupid? He can't even speak, all brawn and no brains.'

Attempting to control the Hellfire Rose, I attempted to strike him with it.

André the idiot tried to block it only to scream in agony as his arm was being burned.

Feeling the pain, I organized myself.

This is why I like fighting idiots; my Hellfire Rises are not quick, so they can be easily dodged, but it becomes a problem when they accumulate and start attacking you all at once.

The more Roses there are, the faster they become.

Gyro could summon a maximum of 10 roses that would mean that after conjuring all ten their power would increase by 1.5 to the power of 10 which is equal to 57.665; that would mean that if a single rose's power was equal to a punch filled with 300 points of nen then when all ten were conjured it would equal a punch made with 17,300 aura points, and he had 10 of those.

His physical attributes would also increase by 1.2 to the power of 10 which would equal to 6.191 times his original power.

If he was ever given the chance to conjure all ten roses, very few could fight back.

Sadly, his roses could only last for 20 minutes before disappearing; so he couldn't summon all ten before the fight.

His nen could summon about 15 Roses, but he couldn't have more than 10 at the same time.

(I went back and added these calculations to the chapter so you guys can better understand Gyro's power)

"Critical Hit"

"Gyro 2-0"

A minute passed as another Hellfire rose appeare infront of me, enhancing both my strength and the rose's strength as well.

Much more heat is released as the entire area is heated up to 70 C, causing all of the spectators to vacate the premises and watch it on TV instead.

Andre appears to be readying for an attack.

He sped up and sprinted towards me with incredible speed.

He uses his nen ability which clearly just enhances his physical attributes.

I responded with Ken while hitting him with my enhanced Hellfire Rose.

"Critical Hit, Down!"

"Critical Hit, Down!"

"5-3 Gyro"

Crack

The sound of breaking bones filled the room.

'Shit, I think my arm is broken.'

As we both hit each other, I took my time to gather my bearings.

Another Hellfire rose appears, with my current nen I can only conjure about 10 Hellfire Roses.

As more heat is released, I can only wonder how Andre is responding to the temperature.

Luckily, the heat my ability releases does not affect me.

I control all 3 of my roses and have them attack Andre the Giant from different directions.

'He seems to have learned from his mistakes and is now dodging my attacks.'

Another minute passes, and a hellfire rose appears from behind Andre and strikes him in the back.

Soon all four Hellfire Roses were burning Andre.

'Oh shit! This is much more painful than I thought.'

Looking at Andre's body, all I could see were his ashes.

I quickly turned off my nen ability.

There was no referee or announcer to be seen; they had all escaped the heat.

'My ability is strong, but if I were to fight a large group and stand in shock from the pain for even a second, it could cause my death.'

'I would have definitely lost without my new ability.'

I now have 10 wins under my belt and can challenge a floor master.
