Part.6

"Use your Boosted Gear, Ise."

Next day. Buchou says that to me before the start of the training.

She is allowing me to use my Sacred Gear that I was forbidden to use since I got into the mountains. She is allowing me to use it now...but what does she want me to do with my Sacred Gear?

"It should be okay to have Yuuto as the opponent."

"Yes."

Kiba comes forward after Buchou urges him. He stands in front of me. Hey, is she telling me to fight Kiba!?

"Ise, activate your Sacred Gear before the mock battle. Let's see...we will start the battle two minutes after you activate your Sacred Gear."

"Y-Yes."

I make my Boosted Gear appear on my left arm just like Buchou orders me to.

"Boost!"

[Boost!!]

The Sacred Gear makes a sound at my words, and I can feel the power coming into my body. With this my power has doubled.

Ten seconds later.

[Boost!!]

My power doubles again. The power I can feel from my Sacred Gear runs through my body.

It's all right that my power is getting doubled, but there are things that I need to keep in mind when I use my Boosted Gear.

You may think there are no limits to my powers increasing, but the truth is that isn't the case. Once I activated my Boosted Gear to see how far I can increase my power but after a few minutes I fainted. The reason is simple. My body can't handle the power as it increases more. When I asked Buchou afterwards,

"For example think that you are a truck. What will happen if you carry more package than the truck can carry? It won't move right? That's how it is."

That's how she explained to me.

The package equals my powers that are doubling. If the quantity of package keeps on doubling, then the truck will decrease in speed and by the end it won't move.

So in other words if the power gets too big, then it puts stress on my body. That's why I fainted. My body which is a vessel won't be able to withstand the increased power.

That's what happened when I activated it for a few minutes. The jewel in the gauntlet made a sound which said [Burst], then my body got heavier and it felt like all my senses froze.

Even if there are no limits to the Sacred Gear, the user which is me in this case does have limits. That's my Sacred Gear's weakness.

Well, it's more like my weakness. It's not the Sacred Gear's fault.

I got my twelfth power up after Buchou ordered me to power up. Then Buchou orders me to "Stop" my Sacred Gear's power up.

"Let's do this, Boosted Gear!"

[Explosion!!]

This sound also represents the stop of the power up and acts as a stopper.

Once the power up stops, I can fight with that increased power for a certain time. The length of time I can use it depends on my action during the power up. The more I move, and the more I attack, it minimises the time. This also affects my stamina, and if I'm in a tired state, then the time will also be shorter. One of the ways to use this Sacred Gear is that I don't receive any damage.

Yeah, that's why my current state where I have no damage and have full stamina is the best time to use the ability of my Boosted Gear.

My power is increasing while during the boost, but it is unstable compared to the time when I stop the boost to use the power up for a limited time. If I move around too much, there are risks that it may change me back to my normal self. For that reason, it's better to stop the boost then use the power up.

It will be wise to run around and hide while getting a boost.

Now, my power is in an unthinkable state because of the two minutes boost. The power I feel within my body isn't normal.

"Ise, I want you to fight Yuuto in that state. Yuuto, I will ask you to be his opponent."

"Yes, Buchou."

Kiba makes his stance by pointing his bokuto toward me after Buchou ordered him.

"Ise, do you want to use a sword? Or do you want to fight with bare hands?"

Buchou asks me how I will be fighting.

Hmm, even if I have a bokuto, I won't be able to use it...

"I will fight bare handed!"

"Very well. Now then, I'll ask the both of you to start."

I also make a stance against Kiba. Well, it's a newbie's stance.

SWISH.

Kiba suddenly disappears from my sight! Oh crap! The trait of [Knight] is speed! Kiba has god-speed! Once I lose sight of him, I will receive the attack—.

BANG!

Kiba's swing came down at me, but I guard it by using my arm. Yes! I can withstand this!

"!"

Kiba makes a shocked expression. He let his guard down! I punch towards Kiba who stopped moving.

SWIFT!

Kiba's body disappears just before I hit him, and my punches cut through the air. Crap! He dodged it!

Where's Kiba? I try to chase him by looking around. ...He's gone! If he isn't in front of me or to my left or right, then he's behind me!

However, I don't see Kiba when I turned around.

! Above me!? When I look up, Kiba is coming down with his bokuto aimed downwards.

BANG!

I heard a nasty sound! Guhaaa! I receive a blow on my head. It huuuuurts!

"Ouch..."

I don't have time to touch the part I was hit and I release a kick towards Kiba who just landed on the ground.

SWISH!

He dodged it again! Shit! It won't hit at all! If my opponent is a [Knight], then will I have a hard time with their speed!?

"Ise! Shoot with block of demonic-power! When you form a block of demonic-power, shoot it with a shape you imagine the most!"

Buchou gives me an order.

A block of demonic-power? I have to do it here? I don't know if it will hit but there's no other choice! I will obey Buchou's order.

I gathered the demonic-power flowing within my body and concentrated it into my palm. There is a block of demonic-power that is the size of a rice ball. Small like usual!

I then shoot it towards Kiba! That instant, I wasn't able to believe what I saw.

GUOOOOOOOOOO!

It's huge! The magic ball that had the size of a rice ball got bigger when I shot it! It reached the size of a huge rock! This!? I get it! It's the power of the Boosted Gear! The huge block of magic got closer to Kiba. The velocity was quite fast as well.

SWISH.

Kiba dodges it easily. Well that's not surprising. Oh, but it won't mean anything if it doesn't hit. That's what I thought, but soon I got rid of that thought.

The demonic-power ball that missed its target went towards the mountain next to the one we are on, and—.

BAAAAAAAAAAAAAAAAAAAANG!!

The mountain blows up while making a huge sound and blast!!

Eh! Eh? Eeeeeeeeeeeeh!?

...A single shot of demonic-power I shot out blew away a single mountain...The mountain has a huge hole in it. It changes the view of it.

...Eh? Are you for real? It actually blew it up? It's a mountain, you know? A mountain.

Because of the sudden turn of events, I didn't know what to say.

[Reset]

The gauntlet made a sound and I can also feel the power leaving my body at the same time. Looks like the time I'm powered up for is finished.

Then I lost all of my strength at once. It feels like my insides became empty. Seems like I used up my demonic-power.

"I'll have both of you stop it there."

Buchou ends me and Kiba's spar. Kiba also put his bokuto down. I also sit on the ground as if I lost my strength.

T-The mountain disappeared.

My heart is beating with that fact. D-Did I do that? I still can't believe it. A-An attack like that actually came out from my hand...

"Good job you two. Now I will hear your impression. Yuuto, how was it?"

Kiba answers Buchou's question.

"Yes. To tell the truth I'm astonished. I tried to finish the spar with the first strike."

Eh? The first strike as in the one I was able to block?

"But I couldn't break through Ise-kun's guard. I was focused into breaking through it. I also tried to knock him down in my second strike by hitting his head from above the air, but that failed as well."

Kiba answers it while laughing out "Hahaha" with a refreshing expression. Kiba put his bokuto to the front to show it to everyone.

...That bokuto is already broken.

"I strengthened the bokuto with demonic-power, but it couldn't give that much damage to Ise-kun because his body was too hard. If we continued, I would only have the option to run around because I wouldn't have my weapon."

"Thank you, Yuuto. That's how it is, Ise."

That's how it is? Is this the thing she told me yesterday when she said, "I'll give you confidence"?

"Ise. You said to me that you were "the weakest and have no talent", right?"

"Y-Yes."

"That's half correct. You, who hasn't activated your Sacred Gear, is weak. However, you become a totally different person if you use the power of the Boosted Gear."

Buchou points at the mountain that was blown away.

"That attack is one of a High-class Devil. If that hits, most people will be blown away."

Are you serious!? Well it certainly does seem like an attack that could blow most beings.

"Your body which went through basic training became a vessel that can handle a Sacred Gear that increases the power drastically. Even now, your body is strong enough to handle the power increase. I told you before, right? You can become the strongest as long as you improve your basics. The higher your initial strength is, the more the power can increase. The basic stamina rises from "1" to "2". Even something like that would become a big factor for you to become strong."

—!

My power is amazing...?

I still can't believe in myself and Buchou says it with confidence to me.

"You are the key to the game. Ise's attack becomes the factor that decides the outcome of the battle. If it was only you fighting, then it would be scary because you would have your guard down while powering up. However, this battle is a team battle. You will have your comrades that will support you. Trust in us. Then, you will become strong as well as us. We can win this!"

—Become stronger. Me?

"Let's show it to those that looked down on you. It doesn't matter if the opponent is Phoenix or not. We need to teach them very strictly in how strong Rias Gremory and her servants are!"

[Yes!]

Everyone replies to her with a strong voice. That's right! I have Buchou and everyone with me!

I will become strong! I will become stronger along with everyone!

I will defeat Raiser Phoenix!

After having new-found determination, the mountain training went through smoothly.

Then we reached the day for the decisive battle.
