Black Four-Leaf Clover: From Check-In

"This...isn't this Asta's Grimoire?" Mimosa froze.

The look at Kuroba was full of disbelief.

No!

It should be said that everyone present, even the Devil who calls himself Megicula is no exception.

It is common sense that one owns a Grimoire.

Now Kuroba not only breaks common sense, has dual attributes Grimoire, but also can control other people's Grimoire.

This is too unexpected.

"Who are you and why are you here to help a human!" Devil suddenly growled.

If Kuroba's dual attribute Grimoire is ineffective against Devil, then this Grimoire with Devil's power is deadly and highly poisonous.

"Hey, senior! It's the first time we meet, you don't need to know who I am, no matter how powerful you were, how strong..."

"As long as you lose, you should be sick now!"

"Oh, yes, I think it's very difficult for you to split out of Megicula's body, otherwise you wouldn't be able to, not even the host Grimoire..."

The voice of the voice seemed to come from the other side, directly hitting the depths of Devil's soul.

For all this, Kuroba didn't take it seriously.

He had only one thought on his mind right now.

"Come on, boy, I'm in a hurry!"

"Got it, Big Brother!"

Kuroba nodded with a smile and looked at Devil, catching the void with his right hand.

Grimoire belonging to Asta, blooming a dazzling black and red light.

A black as ink, like a rusty broadsword, emerged from the magic book.

The Sword of Severing Demons!

Without any hesitation, Kuroba stretched out his right hand, gripping the Demon Severing Sword tightly.

Under the endless devil's power, under the crazily rewinding, the originally three-foot blade spread out in an instant.

Wherever the black light passed, the blade transformed and condensed, turning into the size of a door panel.

Looking at the Devil with a distorted expression, he calls himself Megicula.

There is no trace of bells and whistles, and it straddles directly.

"No!"

"I.....I know who you are, you traitor!"

A hysterical roar sounded, and the words were full of unwillingness.

However, in the face of Kuroba's rush, all resentment paled.

A black light flashed like a radiant light, directly passing over the Devil's body.

The originally distorted body quickly collapsed, as if turning into a vortex out of thin air, pulling away all the Devil's power covering the entire room.

In a blink of an eye, the entire dark room was bright again, and the dark smell was gone.

"Ah...... This...... Is this my Demon Severing Sword? It's so handsome!"

"Senior Luck, Senior Magna, have you seen it?"

Asta came first and blocked the door.

Seeing the extended version of the Demon Severing Sword in Kuroba's hand, his eyes were twinkling with stars.

Luck, Magna and the others also rushed over.

However, the focus is obviously out of touch with Asta.

"Short Douding, is your focus wrong!" Yami said while holding Asta's head.

"Your Grimoire has been used, don't you think there is something wrong with your brain?"

One person, one Grimoire, that is a constant law.

Even Bartley, the reincarnated elf, cannot use Vangeance's world tree magic.

This is enough to prove that this law does exist.

However, now Kuroba has broken this law.

"Ah...my Grimoire!" Asta groaned strangely, and immediately picked out his nostrils indifferently and said, "This Grimoire was originally given to me by Captain Kuroba because he didn't want it. He took it and used it. It doesn't matter!"

Sent?

Those present were dumbfounded.

They finally understand what it is to worry about.

According to Asta's idea, in modern times, stepping on a horse is like a light on the head, and the green is very pleasing.

However, Kuroba didn't take all of this to heart.

He has done so much, all in order to complete the system's check-in tasks.

It's just that there is no way to deal with Devil's underworld magic, and other means.

After that, it might be a bit tricky to face other Devils.

If this reward can have a little effect on Devil, that should be pretty good.

"Ding Dong, congratulations to the host for beheading the split Devil and completing the task of signing in to 363. It took nine minutes and thirty seconds." The system is calculating the reward.

"Ding Dang, the reward phase is successful, and the host gets the Breath of Thunder!"

A warm current of information poured into Kuroba's mind like a source.

After a short period of brain swelling, a series of information about the breath of thunder was imprinted in Kuroba's mind.

If Kuroba remembers correctly, the breath of thunder comes from my wife Zenitsu's breath of thunder in Demon Slayer: Blade.

It can mobilize the power of thunder in the body, synchronize with the breathing of the cells, activate the body to the extreme, and burst out the strongest and fastest Iai Slash.

The power is like thunder and thunderbolts, even the naked eye can't keep up.
