The magic cards I made are absolutely flawless!

At this moment, Dekan must continue Delois's work.

Similarly, this is Dekan's only chance to understand the key principles of the Demon King's Tomb!

Understanding how to fully extract and control the Demon King's magic is not only the only way to rescue Shin and Icardinos.

This is also an indispensable step for Dekan to make his master the strongest partner.

This primordial demon king's tomb contains many complex supreme demonic spells, such as sealing the souls of the dead and borrowing their magical power.

There are even many of Delois's research findings, including some forbidden magical principles beyond the [Demon Seal].

Those were memories that the master had long lost, and memories that Dekan could not research in a short time.

And now, all of this is right before our eyes.

"Master, once I figure this out, you should soon have a physical form."

Dekan thought to himself.

If I can truly master Delois's knowledge and achievements, perhaps the first thing I can do upon returning to the mortal world is to fulfill my promise to my master.

"Then good luck to you. I don't want to stay on you anymore."

Although he spoke of it in a somewhat distant manner.

But in fact, the master had already demonized Dekan's body the moment he saw the Shadow World's prompt.

Her purpose was to prevent Dekan's starting point from being in the Demon Realm, a place where the Demon King should appear in his official demon form.

Or perhaps the special location of the Demon King's Tomb.

If a human were here, they would be directly sealed by the Demon King's magic, but Dekan, who was transformed into a demon by his master, is the absolute controller of this Demon King's Tomb.

Dekan originally planned to tell his master, but before they could even exchange words, he discovered that he had already transformed into a demon form.

This made Dekan feel much more at ease.

"You are now a mature master, and you can assist me on your own."

As Dekan flipped through the book that Delois had been reading, he silently offered his master words of sincere praise.

"?"

"Do you believe I'll undo your demonization right now and make you the first demon king in the world to be sealed in the Demon King's Tomb?"

The master immediately saw through Dekan's provocation and issued a warning to him.

She discovered that Dekan acted as if he had to do a daily chore, and he wouldn't feel comfortable unless he provoked her at least once a day.

After realizing this pattern, the master became even angrier in the face of Dekan's daily provocations.

Sometimes they would even steal his entire day's worth of food, leaving Dekan to struggle alone on his night runs.

"No, no, my dear sister! This useless brother of mine is counting on you to save his life! What I said earlier was that you are the most reliable and trustworthy sister in the whole world!"

Dekan seemed determined to push the provocation to the limit, saying things that were hard to tell whether he was begging for mercy or continuing to provoke his master.

Although Master was always very domineering when he was with Dekan.

But since it is the Demon Realm, there must also be a gentle and calm Talomatti.

It was only after spending nearly half a year together in the Holy Kingdom's Shadow World that Dekan discovered that Talomatti could also be such a healing younger sister.

The more Dekan compared them, the more he felt that his master was a sister from a family with a long line of ancestors.

With her temper, calling her "sister" would mean losing at least two meals. Sometimes, when she got really angry, she would even eat high-calorie desserts like rice.

Unlike Talomatti in the film world, when you call her sister, she will nod seriously and sometimes even take the initiative to share food with Dekanyev.

But if I had to say who I find most interesting to be with...

That would have to be a master craftsman.

Just as Dekan was anticipating his master's reaction.

"...Don't provoke me again, or I won't save you next time."

The master remained silent for a while, seemingly wanting to remove the demonization and teach Dekan a lesson, but ultimately stopped and did not remove Dekan's demonization.

She didn't take this opportunity to engage in unfair negotiations with Dekan, demanding that he promise to provide her with a few meals.

"Huh?"

This time it was Dekan's turn to be surprised. "Oh no! It is a miracle!" he almost blurted out again.

"Do you remember the bet we made last time?"

However, before Dekan could respond, the master interrupted Dekan's chance to speak with his mind.

She seemed to know that Dekan was about to say something that would make her blood pressure soar, so she didn't give Dekan a chance to organize his thoughts.

"Uh……"

Dekan was completely bewildered.

Besides interrupting spellcasting, the master also said something that left Dekan completely baffled.

"That bet about whether Delois and Talomatti had a good relationship?"

After thinking for a moment, he finally realized what was going on and asked.

They did take a gamble back in the Demon Realm Hospital of the Fifth Shadow World.

The content is that if Talomatti in the Shadow World really hates Deloitte, then according to the bet, Dekan won't get to experience the three meals and desserts in the Demon Realm and the Holy Kingdom for a whole month.

Conversely, if Talomatti and Delois have a good relationship, then Dekan will win, and as a wager, Master will have to listen to Dekan once.

After making Talomati cry at the Demon Realm Hospital, Dekan admitted defeat and then fulfilled his bet, allowing his master to enjoy the delicacies of the Demon Realm Holy Kingdom, which are unavailable in the mortal world, for a whole month without restriction.

He didn't know why his master was bringing this up again.

"Actually, it seemed that Deloitte and Talomatti had a pretty good relationship that time, so I can't say I won that bet."

The master remained silent for a long time, until Dekan had turned several pages of the book in his hand before finally speaking.

She seemed to have wanted to talk to Dekan about this for a long time.

However, he was constantly annoyed by Dekan in the real world and didn't want him to be smug at all.

Now, revisiting these familiar places, and for the last time visiting the Demon Realm and the Holy Kingdom, the scenes from back then flood back into my mind.

The master then brought up the topic again.

"Oh well, it's not like I can't afford to lose. If I lose, I lose. I'll win it back someday."

Dekan seemed completely absorbed in the book in his hands, while his mind was elsewhere regarding the message his master was conveying.

He seemed to be trying to analyze what Deloitte had been doing before, attempting to find some information that would be beneficial to the start.

"...Dekan, you haven't been deliberately losing to me all this time, have you?"

The master observed Dekan's reaction, pondered for a moment, and finally asked.

No child cries every day. No gambler loses every day.

Even Clay occasionally wins big.

Moreover, given Dekan's personality, he always wins more than he loses when he's willing to gamble.

The only exception was that he never won against Master.

Even this time, despite Master's own concessions, Dekan still seemed unwilling to win.

Finally, the master felt a little uncomfortable.

"No, that's not true. I just wanted to beat you fair and square this time. I always honor my bets, and it would only make me seem petty to bring up a bet that has already been made."

Dekan seemed to have some difficulty understanding the book in his hands, so he kept turning the pages.

“...This time is an exception. At most, it's a draw because neither of us bet correctly. But I've already taken your bet, so either I compensate you by not using your body for a while, or I make up for it with the equivalent bet you proposed. It's up to you how you want to resolve this.”

After hesitating for a long time, the master finally conveyed his thoughts in this way.

She and Dekan are the same in accepting defeat.

There's nothing you can't afford to lose.

"Oh my, is there really such a good thing?"

"Hurry up and choose, or it will be invalid."

"Then of course I'll choose to listen to me this once. I'm not a foodie like you, so the choice is obvious, okay?"

You're the glutton!

Master was about to retort to Dekan, but for some reason he held back and stopped talking.

"Then I must cherish this opportunity. Once you return to the real world and have a physical body, hehe, there are just too many fun things I can think of in the daily life of our Happy Group."

Dekan's words were filled with a kind of "I'm always incredibly steady" confidence.

"?"

Upon hearing this, the master couldn't help but feel a little regretful.

She had seen all of Dekan's past.

Although Dekan has always been reliable against his enemies.

However, in his daily life with his friends, whenever Dekan is involved, there is a 50% chance that he will directly become a ghost.

Moreover, Master really can't figure out if he's just bad at the game but loves to play, or if he has some inexplicable confidence that he's really not bad at all.

And yet, he still dares to bring his younger sister along to have fun.

It seems like the brother and sister might both crash and burn.
