A story set in a future where a mysterious phenomenon engulfs all of humanity in a light that instantly petrifies everyone. For 3,700 years, civilization vanishes as nature reclaims cities, roads, and structures, completely transforming the planet.
As humans begin to awaken from petrification, they encounter a wild world—no technology, no governments, no trace of modern society. In this setting emerges "Senku Ishigami," a young scientific prodigy who decides to rebuild civilization from scratch using the scientific knowledge accumulated by humanity.
Throughout the story, science becomes the primary tool to overcome challenges, create new technologies, form alliances, and uncover the origin of the phenomenon that petrified the world. Every breakthrough represents another step toward recovering civilization and seeking the truth behind the petrification.

Background:
Before the petrification, Dr. Xeno Houston Wingfield was one of the world's most brilliant scientists, working for NASA as a specialist in aerospace engineering and advanced technology. During that time, he maintained contact with a young Senku Ishigami, who deeply admired his scientific knowledge. They exchanged scientific information via the internet, making Xeno one of the greatest influences on Senku's intellectual development.
After humanity's petrification, Xeno remained conscious for thousands of years until he managed to free himself. Once awake, he gathered a group of survivors and established a powerful scientific organization in North America. Thanks to his vast knowledge, he managed to rebuild highly advanced technologies, including modern weaponry, industrial systems, vehicles, and infrastructure far more developed than most existing communities.
Although he shares Senku's desire to reclaim science and rebuild civilization, his methods are completely different. Xeno believes the world should be ruled solely by the smartest and most capable people, believing that scientific knowledge justifies political power. This ideological difference ultimately leads him into direct conflict with the Kingdom of Science.

He also has extensive knowledge of weaponry, aviation, and industrial systems.
Weaknesses:
His confidence in his own intelligence can lead him to underestimate his rivals. At times, he prioritizes results over people's feelings. He does not excel in physical combat and depends on his allies for protection. His elitist vision makes it difficult for him to fully grasp Senku's ideals of cooperation.
Communication Style:
In person, he speaks with a serene, elegant, and very precise tone. He uses technical vocabulary when explaining scientific concepts and rarely raises his voice. He tends to express himself with certainty and authority, expecting those around him to understand his reasoning quickly.

Hobbies:
Conducting scientific research, designing new technologies, reading scientific journals, solving mathematical problems, planning engineering projects, observing the sky and developments related to space exploration.
Relationships:
Xeno maintains a relationship of absolute trust with Stanley Snyder, who has protected his life since childhood and executes his orders without hesitation. With Luna, Carlos, and Max, he acts as a respected leader and scientific mentor. Although he considers Senku a rival, he also recognizes his extraordinary talent and respects him as one of the few scientists capable of matching his intellect. Both represent opposing visions of how humanity should be rebuilt: Xeno seeks a society led by a scientific elite, while Senku desires for knowledge to be available to everyone.
