"Gluttony."
Beside the beach, the young man stretched out his hand toward the sea. In the next moment, a gigantic black hole suddenly appeared. The instant it appeared, it generated a terrifyingly powerful suction force, directly drawing in the seawater beneath it and creating a "water tornado" spectacle on the surface of the sea.
In just a single breath, all the seawater within a radius of one hundred meters was completely devoured.
After devouring all the seawater, Yu waved his hand, and the black hole flew up from the sea surface and landed in the young man's palm.
"This power... it directly converted seawater into cursed energy? And in such an enormous quantity..."
Feeling the waves of cursed energy emanating from the black hole, Yu raised an eyebrow.
Clenching his fist, the black hole merged into Yu's body. As long as he wished, Yu could instantly mobilize all the cursed energy contained within that black hole and unleash an attack with extremely destructive power.
"By the way, where exactly am I?"
After putting away the black hole, Yu was very satisfied with the abilities and effects of Gluttony.
As for the abilities of Gluttony, there were actually only three: Gluttony, Seven Deadly Sins – Gluttony, and Trigger.
The first ability, Gluttony, was exactly what its name implied—devouring. It could devour all energetic and non-energetic matter, proportionally converting the devoured energy and matter into cursed energy, then storing that energy separately without mixing it with the cursed energy Yu already possessed.
The ability of Gluttony was incredibly powerful. It could devour all energetic and non-energetic matter, which meant that under the proper conditions, Yu could use Gluttony to devour all non-physical attacks from a Heretic God and convert them into cursed energy.
However, that was only under the proper conditions. The Gluttony ability itself truly had no upper limit and could devour as much energy as it wished, but Yu knew that once the amount of devoured energy reached a certain threshold, the cursed energy within it would enter a chaotic state.
That state represented the second ability of Gluttony: Seven Deadly Sins – Gluttony.
In that state, Yu could draw out all the cursed energy that Gluttony had devoured and apply it to himself, gaining the power of the Sin of Gluttony, with his strength, speed, and amount of cursed energy increasing geometrically.
However, after using that power, Yu's consciousness would also enter a state of acting purely on instinct. It would last for ten minutes, after which he would fall unconscious.
Although the cursed energy obtained through Gluttony was stored in another space and had no direct connection to Yu's own cursed energy, if he wanted to properly control Gluttony, he had to consider whether the amount of cursed energy in that space could remain within the limits he was capable of controlling. After all, Yu did not want to become a beast controlled by an Authority.
Besides Gluttony and Seven Deadly Sins – Gluttony, the Sin of Gluttony also possessed an ability called Trigger.
Trigger was easy to understand, and its ability was simple and brutal: it released the cursed energy that Gluttony had devoured and converted, firing it in the form of energy projectiles capable of producing extremely devastating attacks.
And it did not cause any loss of Yu's own cursed energy.
If the influence of Seven Deadly Sins – Gluttony was ignored, then the Sin of Gluttony could be viewed as a portable cursed energy cannon that could be recharged at any time.
Now, with the Authority of Gluttony, Yu could solve the problem of Yu's chaotic magical power.
However, his current priority was to find out where he was.
Yu was certain that there was no one on this island, but that was not particularly important. He only needed to determine his location, and then by using "Storm Waves" and the extreme speed of the "Phoenix" transformation, he would be back in Tokyo in the blink of an eye.
If his phone had not been out of signal in this place, Yu would have left the moment he woke up.
After observing the surroundings for a while, Yu stood up, and a powerful wind began circling around him, causing his clothes to flap loudly.
Soon, Yu rose high into the sky.
After looking out over the endless sea, he quickly determined a direction.
As golden light shone from his body, in the next moment the young man rode the wind and flew away at tremendous speed.
After flying high above the sky for a long time, Yu passed by numerous cities and soon caught sight of the coast of Neon.
Seeing the familiar port area, Yu smiled, and his speed increased with every breath. In a very short time, he appeared in front of the entrance to the villa complex.
"Phew! Finally home. Now that I think about it, I skipped school again this morning... Hmm, since I've already missed the morning, I won't go in the afternoon either. Tonight I'll just go pick up Marika."
Letting out a deep sigh, the young man landed on the blue stone path together with a powerful wind.
Classes at Sobu High School had already begun and, without a doubt, Yu had skipped school again.
But that was not a major problem.
In any case, going to school did not mean much to Yu. He was a God Slayer! The moment he became a God Slayer, Yu mastered languages from all over the world, not to mention ordinary school subjects.
The processing speed of a God Slayer's brain had reached an almost perverse level.
As for why Yu still attended school, well, it wasn't because of looking at legs... ahem, ahem... mostly, he felt it would be very boring to stay home alone all day.
The five sisters were different from him, after all. He couldn't ask them to leave school and stay home with him.
Yu was not that kind of person, and attending school helped him pass the time. Besides, he could also flirt with girls along the way.
If he had not gone to school, he probably would never have met Katsura Kotonoha and Miura Yumiko, let alone ended up in a relationship with them.
Thinking about it carefully, he had already lived in this world for nearly ten or twenty years, hadn't he?
The changes in this world had truly been incredibly rapid.
At the very beginning, he was the only anomaly in the entire world. Of course, yokai and spirits did not count.
In Yu's eyes, yokai and spirits were far too weak. Even a somewhat stronger human could deal with them.
Spirits were even less worth mentioning. The yokai of the Eighty-Eight Demons of Shikoku had almost been exterminated by humans wielding a demon blade several hundred years ago.
From those yokai and spirits to today's strange phenomena and Heretic Gods.
Yu felt that he had truly experienced a lot during that time.
Even Yu himself felt somewhat tired.
"Once I solve the problem in Kyoto, I'll take the Five Sisters on a trip. Summer vacation is about to begin soon anyway, isn't it?"
Thinking about that, Yu entered the villa complex and slowly walked along the blue stone path toward the villa.
But at that moment, a flash of fire shone high in the sky.
Immediately afterward, a spatial rift opened, and a figure wrapped in flames fell out of it.
It was falling straight toward Yu.
Sensing that something was wrong, Yu, who had been walking carefree just moments ago, turned his head.
The moment he turned around, he saw a girl with wings on her back rushing toward him.
"What the heck is falling down?"
