Leo survived the academy’s poison experiments, developed his shadow abilities, and trained through extreme conditions on the journey to Tiyama City. As Black Skull Academy launched an invasion and abducted civilians, the vice dean sent Gru to retrieve Leo and protect him.
Leo survived the Six-Academy Joint Championship alongside Alice while pursuing experiments with an atomic bomb and his Shadow Talent. As the tournament entered its final year, thousands of apprentices surrounded their cave, and Alice charged out with Leo following.
After winning the tournament and advancing through Hunter bloodline refinement, Leo agreed to help the Wizard World invade Jeft World. He opened the passage and held off the Dark Night Clan’s forces while the altar gathered energy, but the Pope arrived as Leo realized he could not withstand the Demigod’s power.
Leo helped conquer Jeft World, settled near Alice at the Tower of Elements, and spent decades researching nuclear fission and elemental defenses. He then joined Alice on the Black Tomb World expedition, where the Eyeless Spiders overwhelmed their squad and forced Leo to use his shadows to buy time for a retreat.
Leo survived the Black Tomb World expedition, captured the remaining Jiayehe, and returned to Wizard World with Alice. After advancing to a level-one elemental wizard and gaining Yaoyao as a companion, he traveled with Benji to Jeft World, where he prepared to search for Diana, Goddess of Darkness.
Leo recovered the Goddess of Darkness’s remains, used them to create powerful equipment, and modified the Gulu Beasts. He dominated the First-Level Wizard Tournament, withdrew after Gru’s death, and returned to his research before a Level-Six wizard announced a punitive expedition to the Giant World.
Leo led the defense of a forward fortress in the Giant World, using atomic bombs and nuclear fission to survive the native armies until the wizard counteroffensive began. After earning a Third-Class Wizard Medal, he began questioning Wakeda about the giants and their world, and prepared to study Wakeda’s blood.
Leo secured Kampas’s agreement to join the Wizard Alliance, helped defeat the God of Beasts, and settled Wakeda’s tribe near the mothership. After learning that Green Cottage had hidden Earth’s survivors, Leo began a two-hundred-year plan to strengthen himself and tested a vast Gravity Rune Array.
Leo protected Tiyama City from the Black Skull Academy, then accepted a mission to find Alice in the isolated Tiger World. After reuniting with her, he traced the rebellion to a powerful being altering the Tiger Beastmen and discovered a vast altar at the center of their city.
Leo advanced to a Level Two Elemental Body Refinement Wizard, developed controlled nuclear fission, and traveled to the Undying Body Wizard Academy to learn about the Stone of Indestructibility. He agreed to help defend the academy as war approached, then crushed an intruder who had abducted Tao Mia and another apprentice.
Leo defended Undying Body Academy through the end of the three-academy war, then returned to his tower and fused the Stone of Indestructibility into his body. After raising his defenses and reuniting with Alice, he left on the expedition to the miniature Homo Sapiens World, promising to return within twenty-five years.
Leo uncovered the great tree’s control over the Homo sapiens and survived its awakening while the wizard forces fought its branch. After the four Stigmata Great Wizards won, Leo joined the mission to gather the shattered planet’s resources and Planetary Core.
Leo secretly gathered planetary core, returned to Wizard World to restore the Tree of Life, then led the expedition against Rota World’s Cyborgs and searched for the Diro People’s sacred land. The Beast Blood Boiling Stigmata Wizard identified the sacred land as his fortress, stripped Leo of his merits, and left him in debt while Yaoyao bargained for one of Leo’s shadows.
Leo helped the wizard army defeat the Metal Legion and seal the metal giant, then returned home and studied the Beast Blood Boiling Stigmata Wizard’s notes. After Alice advanced to Level Two, Leo and Alice settled in a seaside village and began a quiet life among its residents.
Leo and Alice built Falling Sunset into a prosperous city, then returned to wizard society and were caught in the Purple Flame Stigmata Wizard’s attack. After Alice died and Leo survived, he grew stronger and fought through the slave armies toward the stigmata wizards and the spatial passage.
Leo avenged Alice by killing the Purple Flame Stigmata Wizard, who escaped Black Skull’s control and left him his inheritance. After the rebellion’s forces withdrew, Leo claimed Earth and Purple Flame Academy’s territory, then met the humans of New Earth as their ruler and ancestor.
Leo built New Earth’s wizard academy into a force capable of responding to planetary disasters, while his apprentices spread wizardry and advanced in the Wizard World. After the World Will’s origin energy restored much of Leo’s strength and Yaoyao’s Shadow Space transformed, Leo left New Earth and returned to the Wizard World.
Leo transformed the Godslaying Staff and Wizard Robe, then joined an expedition to Ant God World and used his new strength to battle its ant armies. The World Lord and billions of ants attacked the mothership, and Leo entered the fight as the wizard line began to falter.
Leo’s battle with the World Lord trapped him and the armies in the Hundred-Page World, then brought him back to the Wizard World. When a spatial rift revealed a miniature world, competing wizard factions disputed its ownership until the Sword of Nirvana Stigmata Wizard made its sovereignty the prize in a deadly competition.
Leo won the tournament, took control of the world, and spent years preparing New Earth’s forces to invade the Gnoll World. He killed the God of Gnoll, then began advancing toward Stigmata as Yaoyao carried him back to the Wizard World.
