Monarch of Gluttony: System of Sin

As the key awakened, it also started changing its color with time. The key started transforming, similar to what the main key did.

The transformation was much slower than it had been in the real world, but that slow transformation also gave Azekiel a moment to talk with his Mirror Reflection.

Even though Azekiel was talking to himself, at times he forgot that the Mirror Reflection was him in essence and treated it like a stranger who couldn't understand what he had been thinking.

After Azekiel expressed his opinion on the topic of his mother, silence ensued. The Mirror Reflection didn't speak much in response, as Azekiel seemed quite convinced that he was going to kill her. As for the reality of the situation and if he could actually do it, it was hard to guess even for him.

The key finished its transformation, and the magnetic attraction stopped as soon as it was a success. The key started falling down, only to be caught by Azekiel's Mirror Reflection.

Azekiel's mirror reflection felt the key which was freezing cold in his hand. It was as if the key was made from a small block of ice, which was even colder than it should've been.

Even though the Mirror Reflection had some resistance to the cold, it was still too much for him. He even felt as if his hand was going to freeze if he kept holding the key for longer.

The Mirror Reflection tossed the key toward Azekiel right away, not wanting to hold it any longer. According to him, if Azekiel was here to take the key, he should be the one holding it.

Azekiel watched the key flying toward him. He raised his hand and caught the key. Even he was surprised at how cold the key actually was, which he felt only when the key touched his hand.

He kept the key in his storage ring right away, not intending to deal with the cold yet. He was also sure that the key wasn't going to be as cold when he was out of the mirror Realm.

He also made sure to keep the two keys separately. While he kept the main key in his inventory, he kept the inverse key in his storage ring to keep them away from each other.

"Now that you're done, shall we leave?" The Mirror Image asked.

To get out of this place, Azekiel needed to go through the same route he came from, which meant a long journey back as well.

The two of them left the Reverse Castle of Infinity and flew back where they came from, climbing to the higher floors.

The Mirror Reflection brought the real Azekiel back to the room with the mirror from where Azekiel could leave.

The two men stopped before the Mirror.

"Thank you for the help." Azekiel didn't thank people often, but it was his own Mirror Reflection, so it wasn't the same as thanking others. Moreover, without the support of his Mirror Reflection, he couldn't have the Inverse Key.

"You don't need to thank yourself," the Mirror Reflection said in response, smiling. "I was only helping myself."

"Best of luck for the future, my other self. I really wish you success. But just a reminder... Don't let yourself get swayed like last time. If you're going against all your emotions, then you better be against all your emotions, including your real family. If you have to kill her, don't hold back the next time."

"Hah, so you also want her dead," Azekiel smirked. "At least we think alike on one thing..."

"Who knows... If I think she should die, maybe deep inside you don't?" The Mirror Reflection let out, slightly amused.

Azekiel frowned as he heard the suggestion. How could it be possible that he wouldn't want her dead? That person had killed him! If anything, he wanted to kill you more than once, just to make sure that even her soul wasn't left in fact.

"Again, you're back to nonsense." Azekiel turned his back on his Mirror Reflection and walked inside the mirror.

As Azekiel left, the mirror reflection just stood in silence, watching the Mirror Realm break apart. The mirror realm came into existence temporarily, and now it was breaking apart as Azekiel left.

With that, it was also his last moment since he was sure that Azekiel wasn't going to return ever again as his strength was going to be beyond the threshold limit of the mirror.

Piece by piece, the mirror realm broke apart.

****

Azekiel had stepped out of the mirror. He took one last glance at his reflection in the mirror before he left the place.

The King and all the Royals of this Palace were hiding in their rooms for a long time, but they can finally come outside after making sure that Azekiel wasn't anywhere in the Palace.

With Azekiel's disappearance from the Palace, all the Nobles thought that Azekiel was already gone.

​ The King was standing right at the entrance of the castle, observing all the destruction.

His Nobles were standing right behind him as he was prepared to address the Guards that were still left and the citizens of the city that were told to gather outside the castle now that Azekiel had supposedly left.

"My brave citizens!" The King spoke at the top of his lungs, addressing the crowd. "Today, we were under attack! We were attacked by a fierce demon that intended to destroy the Royal Family!"

"Today, we lost many of our brave men at the hands of that Demon, who thought he could destroy the Royalty and what this Kingdom stood for! But the demon forgot one thing!" he declared. "He forgot that we are still alive, and we aren't going to bow before any Demon!"

"Through our effort and bravery, we fought the Demon, and we made him run away! Our Kingdom is victorious as the Demon was nothing before your brave King! So be proud! There's no reason to be scared!"

As the King gave a speech, he didn't realize that Azekiel was already back and standing right behind him.
