This is the story of a magician and an elf girl.

The underground world covered by fluorescent plants would have been occupied by other creatures and turned into nests even if no one lived there. However, since the group of intelligent life forms who called themselves "Adventurers" came here, this place has become a large guild of adventurers in just a few days.

Several months after their establishment, they launched a large-scale seven-day war with the demon god "Hera" and won the final victory. Although many people died, it did not exceed half. Now those who are left... are preparing their combat power for the final decisive battle.

"Harder! Over there! Don't let up!"

"Yes! Master Jack!"

"Yes! President!"

"It's the acting president! How many times do I have to tell him?"

Due to the departure of the former guild president, Jack, who now leads the Adventurer's Guild, has become the acting president, while Wendy and Athena have volunteered to serve as vice president and assistant. Frankly speaking, Jack would rather Athena become the president herself so that she can better utilize her knowledge and experience as the former president, but she said... If he does this, the former president will definitely feel that he has taken advantage of the other party's trust with bad intentions when he comes back, which is indirectly equivalent to robbing the entire guild... It has to be said that Jack, who had no choice but to do as he was told, actually has the temperament of a leader, and the other adventurers should not gossip about him.

After all, everyone saw that day how much effort Jack put in to regain the former president's position, but he was still beaten to a pulp by that magician. An ordinary person would have been eliminated as a loser in the first blow and would not have been able to fight with that monster for more than two times.

And... Jack did it, even more than ten times, and the adventurers had no choice but to hand over the position of president to him.

"...Alas...it's been a month...where have you been...damn it..."

"…Are you thinking about Ms. Linna…?"

Wendy, who was sitting beside Jack and helping him, was naturally worried about the elf girl. She had been with her for several years since they met, including the magician. Who knew that they would never come back and disappear from her sight. After that, the humans and the orcs began to learn each other's language, because the intellectual pioneers took away the standard language they had agreed on, and people's lives began to become unable to even have normal conversations.

Fortunately, Athena was still alive. She served as a teacher and taught each adventurer each other's language. Everyone studied very hard, and it took less than two weeks for everyone to communicate harmoniously again.

If Athena wasn't there... Jack honestly had no idea what to do. Especially Wendy, who was the leader of the orcs, was worried that humans and orcs would fight each other because of this. It was a blessing in disguise that he didn't lose Athena, such a big figure.

This is also thanks to Wright, but to be honest, it was the guy who saved Wright.

"…Nothing…I'm just a little anxious…There's been no news for so long…The tree spirits have disappeared…The earth spirits are gone too…We can only rely on ourselves…I'm really worried…"

"…We can definitely do it…don't worry."

"...Ah...Of course...As long as we are together...I will..."

They snuggled together and their relationship became closer because of the loss of Linna. Now, even putting their lips on each other's lips is just a trivial matter in daily life.

However, the days of peace will not allow them to continue like this.

"Well...this is..."

"…What…what happened! Jack…"

"...There is a... very bad feeling... that runs through my body... just like... at that time..."

The shudder that coursed through Jack's body stimulated his magical veins, and the vague outline of the armor seemed to reflect the tense vigilance in his heart - the sense of crisis that could not be underestimated was spreading an uneasy atmosphere.

"Could it be that……"

"... Where is Athena..."

"In the usual place..."

"... Let's go, she should know something."

Jack hurried to where Athena was, hoping that his imagination would not come true.

"Goddess, do you feel it..."

"You also felt it... I had a bad feeling just now... After carefully observing with my power, I realized... the law and order were seriously interfered with just now... And there is only one person in the world who can do this..."

"...As expected...it's that magician..."

"... Sir John..."

Athena, who was sitting in the pavilion, naturally noticed the situation. As a goddess, she possessed the power of authority and the unique perception ability of a goddess. If anything happened in the world, she would be aware of it at the first time.

"Well... he is now using a very powerful force to interfere with the laws... it is usually difficult to detect... but he has not stopped using it since just now... he has never used such a huge force in the past... even if he encounters a problem... with his strength, he should be able to solve it in a few seconds..."

"That means... he... has already--"

"——Hmm... I'm afraid... he's currently in a standoff with Satan."

"!"

"!"

According to Athena, once a magician obtains the power of Satan, the balance of the world will be destroyed. The magician will no longer be bound by laws and cause and effect, and he will gain the power to change the world.

The only one who could stop this from happening was Linnae.

Although he didn't want to think that way, Jack could only say...

"… Linna…did she fail…"

"…How could it be possible…The only one who could stop Lord John…Ms. Linnae should be the only one…Why…"

"...No, I'm afraid he couldn't do it...According to the magician's personality...he should have abandoned her in a safe place from the beginning...Now he is probably stepping into the cave where the devil lives alone...alone...challenging an opponent who has absolutely no chance of winning in this world. A place like that...he wouldn't take her to, Linna must still be alive."

"...I hope so..."

Even if Athena said that, Jack still couldn't rest assured - Linna... please... don't let anything happen to us... without you... we have no hope...

"Ugh... Here it comes again... A very powerful force... In the conflict... It completely ignores the constraints of the law... Again and again... This won't work... I have to correct them, otherwise the law itself won't be able to bear it - activate the power, find the correction point..."

Athena is a Valkyrie in charge of strategy and war, and also the goddess of wisdom. In the past, she has created countless prototypes of architectural crafts, is the founder of people's social life, and is the guardian of laws and order. These achievements have brought her a certificate, the power of "Supervisor of Pioneering History".

Therefore, Athena is able to supervise and interfere with the laws of the world to a certain extent. For example, the "skill tree" that adventurers have is a blessing bestowed by Athena's power. The magician's contribution is naturally not without merit, because Athena is like a reviewer who corrects and evaluates unreviewed laws. She can insert the power formula and skill blueprint brought by John into the law and order - and then give it corresponding rationality. In this way, the "skills" can be applicable to the laws of this world and become one of the laws of physics.

However, the magic John used was different.

Although people can also use magic, the degree is definitely not comparable to that of a magician. Even if Athena uses all her strength, it is impossible to insert such a reckless power into the laws and order. Even if she really adds it in, the balance of the world will collapse, John's huge power will be free from the constraints of the laws, and the order symbolized by all things will collapse.

Simply put, the icebergs will melt, the grass and trees will suffocate, heavy rains will fall on the desert, and the environment will continue to deteriorate - what will eventually happen is the end of the era.
