Ki

"Good, now do the same."

"What?"

"I said do what I just did."

*Grim and Asta look at each other.*

"Pffthahahahahahahahahhahahahahahahahahahahahaha!" The two burst out laughing with Asta hugging his gut while Grim rolled on the floor. "Oh God! Hahahahahahahahaha, do the same he says! Hahaha did you hear him Asta? He said do the same! Hahahahahaha."

"...."

Looking at the two of them laughing, a vein appeared on Yami's forehead.

"Holy shit I can't breathe!" Grim laughed wiping away his tears.

While this was going on, Licht looked over his grimoire.

"I get it now, so this is dark magic."

[Light Recovery Magic: Healing Ray of Light]

Activating a new spell, the wound Yami left on his cheek shone brightly before closing up and disappearing.

"That's better."

'He can also use healing magic...'

Seeing this, both Grim and Asta stopped laughing.

"Well would you look at that, I guess guys with tons of mana can do a lot of things." Yami said glancing over at Grim.

"Don't look at me like that, I'm pretty sure that I can't do the same."

"Have you tried?"

"...."

"Tch, guess there's no time like the present." Yami said while waving his sword to defend against another light shard. "Oi brat, go get hit by one of that pasty dude's attacks and then heal up from it."

"What!? Are you dumb? What if I die!?"

Walking over to his side, Yami grabbed him by the face and started squeezing tightly.

"Who do you think you're calling dumb you little shit? And so what if you die? Just surpass your limits and come back to life."

"The fuck do you mean come back to life you psycho! No normal human can come back to life after dying!"

Hearing him being called a psycho, Yami's grip tightened.

"Ow ow ow!! Let go!!"

"If I said do something then just go and do it."

"I can't even see his attacks! How do you expect me to copy you!"

"Tch, you stupid fucking brat, you already know how to know it."

"What?"

"Oi short stuff listen up, this concerns you to."

"Eh?" Asta looked confused.

"The thing I've been reacting to this entire time is something that the people from homeland call Ki."

"Ki?"

"The bodily energy that people give off when their eyes move, when they breathe, when their muscles contract and just their presence alone. That's what we call ki. You must then feel that ki and then move according to what you perceive that the person will do next."

"So ki is basically just guessing what the person will do next? Doesn't sound to impressive." Grim said feeling like Yami was glorifying ki to much.

"No you idiot!" Yami's grip tightened again.

"Ow! Fuck! You don't need to squeeze me if I don't understand!"

Ignoring him, Yami continued his explanation.

"Both of you have experienced this before right?"

"We have?"

*Flashback to Asta finding Valtos by feeling his presence during the zombie attack*

"Oh yeah." He nodded.

"And you Grim, ever since your little spat with Luck and shorty over there, you've been using it subconsciously."

"I have?"

"Yeah, thinking about it now its actually really weird that you can do it. Are you sure you're not from the land of the rising sun?"

"Dude, I have amnesia! There's literally no point in asking me this!"

Dropping him to the ground, Yami quickly slashed at a couple more light shards while continuing the explanation.

"By using my ki, natural power and mana, I'm capable of not only reacting to attacks at this level, but I'm also able to counter them. In a sense, I guess you can call me a magic swordsman."

"A magic swordsman?" Asta and Grim repeated.

"Yeah, in this regard I guess Grim's closest to me."

"What about me!?" Asta asked with sparkling eyes.

"You? You don't have any mana so you can't be a magic swordsman."

"Oh." Asta's enthusiasm dropped.

"But your natural power is higher than Grim's and since you can use anti-magic I guess that means you can be an anti-magic swordsman."

"Woah!"

"By natural power, do you mean muscles?" Grim asked skeptically.

"Yeah."

"Oh... Cool I guess."

'While I may have trained my body and can use [Breath of the Beast] to improve my physique, I guess I still can't completely match up to Asta... That God really did screw me by only giving me 5 years to get stronger.'

Chuckling to himself in his head, Grim climbed to his feet.

"Oh? Gonna go and try learning healing magic?" Yami asked.

"What? Fuck no! I'm gonna go test out that ki thingy. You've said that I've been doing it subconsciously before right? If that's the case how come I couldn't react to that guy's attack?"

"Dunno, go figure it out." Yami shrugged and pointed at Licht.

"Tch." Grim kissed his teeth before walking towards Licht.

---

"My lord, let me deal with this one." Valtos asked Licht.

"Hmm..." Licht frowned as he looked at the approaching Grim.

"Very well. Also take that magic-less boy's grimoire when you have the chance."

"Yes my lord." Valtos bowed before turning his sights onto Grim.

'For turning your sword against lord Licht, I will punish you!!'

Gathering mana into his right hand to create and orb of magic.

---

'Okay Grim, you can do this, its just like Yami said, you've been doing this subconsciously all this time, how hard can it be to actually do it if I pay attention-

*BANG!!*

Spinning around, Grim manifested his beast swords into his hands and slashed at an orb of magic that came flying out of a small portal.

'Was that it? No, I sensed his mana and not his ki.'

*BANG!!*

'Dammit! I did it again.'

*BANG!!*

'Fail.'

*BANG!!*

'Fail.'

*BANG!!*

'Fail!'

'Goddammit Grim! FOCUS!'

Calming down, Grim controlled his breathing and closed his eyes.

'Remember the sensation I felt when fighting against Luck.'

*Breathing in* *Breathing out*

"To close your eyes in the midst of battle! How arrogant you magic knights are!" Valtos sneered before charging another ball of magic.

It was just a shame that what he had said couldn't be heard by Grim as he had immersed himself in his own world.

'Feel it in the air, in the earth, in the people... feel it all around us.'

*Breathing in* *Breathing out*

"What's he doing?" Asta asked.

"He's refining his ki." Yami answered.

"Refining it?"

"Yeah." He nodded. "He was already using it before, now it looks like he's grasping that feeling again and going above it."

"Going above it?"

"Just watch."

---

"DIE YOU CLOVER KINGDOM TRASH!!" Valtos screamed before launching a much more powerful orb of mana through his portal.

'THERE!!' Grim's eyes snapped open as he moved his arm in a similar fashion to Yami to slash at the attack without turning to face it.

"Holy crap he did it!" Asta gasped.

"No." Yami shook his head. "Look at his eyes."

"His eyes?" Asta looked closer but couldn't see anything wrong with his eyes.

"What's wrong with them?"

"Heh, that kid really is a monster, he's seeing the world in a completely different way from us." Yami smiled.

"A different way?"

What Yami was saying was true, after getting a grasp of ki, Grim felt that there was something laying deeper inside, something that would was much Much greater.

"So this is it huh." Grim smiled as he looked down at his swords and back up at Valtos. "This is the Transparent World."
