The morning of the quarterfinals arrived with unseasonable cold.
Rin stood in the competitors' preparation area, watching his breath mist in the air. Around him, the other seven quarterfinalists made final preparations. Each one was a proven fighter who'd dominated their bracket.
"Nervous?" Kira appeared at his elbow, holding a steaming cup of tea.
"Terrified," Rin admitted, accepting the cup gratefully.
"Good. Overconfidence kills more summoners than weak bonds." She pulled out her notebook. "Your opponent is Theron Ashcroft. Third year, Gold rank fifteen. His summon is a Magma Titan. Twelve feet of living lava and stone."
"Weaknesses?"
"Slow. Predictable. But devastating if it connects. One hit from those fists and you're done." Kira's expression turned serious. "Rin, about last night. You left the medical wing. Where did you go?"
"I needed air."
"Don't lie to me." Her voice sharpened. "I saw you climbing the eastern tower stairs. Did you meet with Shade?"
Rin was saved from answering by the announcement: "Quarterfinal Match One: Rin Eldraven versus Theron Ashcroft. Combat Circle One. Competitors, please proceed."
"We'll talk after," Kira said firmly. "And you will tell me everything."
Combat Circle One was the main arena, positioned where every spectator could watch. Rin walked onto the sand to thunderous noise. Half the crowd chanted his name. The other half booed, still viewing him as dangerous and unnatural.
Theron Ashcroft waited on the opposite side. He was massive, easily six and a half feet tall with shoulders like a bull. Burn scars covered his arms, badges of honor from years bonded to a fire entity.
"Heard you beat Lyanna yesterday," Theron called across the arena. "Impressive. But spatial tricks won't save you against raw power."
The referee, Professor Graves himself, stepped between them. "Quarterfinal rules: match continues until surrender, incapacitation, or ten solid hits. Lethal force is prohibited but maiming is permitted. Medical staff are standing by." He looked at both competitors. "This is where amateurs end and true summoners begin. Show me what you've learned. Summon when ready!"
Theron activated his mark, and the arena floor cracked. Molten rock bubbled up, forming into a humanoid shape that solidified into the Magma Titan. Heat radiated from its body in visible waves. Its fists glowed white-hot, and each step left molten footprints in the sand.
The crowd roared approval.
Rin touched his summoning mark, feeling the resistance from the containment bracelet. "Malachar, we need to be smart about this."
"Agreed. That thing is a furnace. Direct contact will burn even me." The demon lord manifested, his armor gleaming. "We need to end this quickly before the heat becomes overwhelming."
The Magma Titan didn't wait. It charged with surprising speed for something so massive, the ground trembling with each step. Its fist came down like a meteor.
Malachar dodged, but the impact point exploded in a spray of molten rock. Droplets splashed against his armor, sizzling. The demon lord hissed in pain.
"First hit!" Professor Graves called.
"That barely grazed me," Malachar protested.
"Contact with magma counts as a hit. Keep your distance!"
Easier said than done. The Magma Titan was relentless, each attack creating pools of lava that made the battlefield increasingly hazardous. Malachar leaped and dodged, but the arena was shrinking with every passing second.
"This is their strategy," Rin realized through their bond. "Turn the entire arena into a death trap. Force us into close combat where the heat advantage is overwhelming."
"Then we need to cool things down." Malachar planted his sword in the ground. "Time to use a technique I haven't shown yet."
Dark energy poured from the blade into the earth. Where it touched molten rock, the lava crystallized and went black. The heat in the immediate area dropped noticeably.
"Abyssal Frost," Malachar explained. "Not true ice, but the cold of the void. The absence of heat rather than freezing water."
Theron's eyes widened. "What? No fire-type should be able to counter magma!"
"I'm not fire-type," Malachar said coldly. "I'm entropy given form."
The Magma Titan roared and attacked with renewed fury. But now when it struck, the void-touched ground didn't melt. It cracked and shattered instead, creating uneven terrain that disrupted the titan's movements.
Malachar pressed the advantage. He moved in close, his sword striking at joints where the magma was cooler and more vulnerable. Each hit chipped away at the titan's structure.
"Second hit! Third hit!"
The titan tried to grab Malachar in a bear hug, attempting to use its body heat as a weapon. The demon lord drove his shoulder into its chest and unleashed a burst of void energy point-blank.
The titan's core destabilized. Cracks spread across its torso, dark lines spider-webbing through the glowing magma.
"Fourth hit! Fifth hit!"
"Titan, molten regeneration!" Theron commanded desperately.
The titan's body began pulling in nearby lava, trying to repair the damage. But Malachar didn't give it time. He grabbed the titan's arm and twisted, using leverage and superior technique to throw the massive creature across the arena.
It crashed in a spray of molten rock and ash.
"Sixth hit!"
The crowd was on its feet now. Rin felt the strain through the bond. Maintaining Abyssal Frost while fighting was draining Malachar's power rapidly. They needed to end this.
"One more push," Rin thought to Malachar. "Everything we have."
"The corruption will spread."
"I know. Do it anyway."
Rin closed his eyes and loosened his mental grip on the containment bracelet, allowing more power to flow through their bond. The corruption marks on his neck flared hot, spreading visibly up to his cheek.
Malachar's form solidified, became more real. His eyes blazed brighter, his armor gleamed darker. The demon lord raised his sword high, and it began to burn with crimson-black fire that made the titan's heat look like candle flames.
"Abyssal Ruin," Malachar intoned.
He brought the sword down in a vertical slash. A wave of destructive energy ripped across the arena, carving a trench through sand, rock, and lava. The Magma Titan stood directly in its path.
The wave struck, and the titan simply... came apart. Its structure couldn't withstand the concentrated entropy. It dissolved into rapidly cooling stone and ash.
"Seventh, eighth, ninth, and tenth hits! Match concluded! Winner: Rin Eldraven advances to semifinals!"
The arena erupted. Rin dismissed Malachar and immediately collapsed to one knee, gasping. The power drain was immense. Through blurring vision, he saw Theron being helped from the arena, looking stunned.
Professor Graves approached. "Impressive. Ruthless. Efficient." He lowered his voice. "And stupid. Look at your face."
Rin touched his cheek and felt new corruption marks. They'd spread past his jaw to his cheekbone. The right side of his face was now nearly half-covered in geometric black patterns.
In the stands, Professor Corvin stood abruptly, her face pale. Headmaster Silvanus beside her looked grim.
"The semifinals are in two hours," Graves continued. "Get to medical. Now."
Rin stumbled toward the exit. The crowd's cheers felt distant, muffled. His vision swam, and he nearly fell before strong hands caught him.
"I've got you." Kira's voice, tight with worry.
She half-carried him to the medical wing, where Professor Corvin was already waiting.
"Forty-four percent," Corvin said after running diagnostics. "You're six percentage points from the critical threshold." She looked at him with something between anger and despair. "One more fight at that intensity and you'll cross fifty percent. Rin, you have to withdraw from the tournament."
"I can't."
"You must! Your humanity is at stake!"
"My life is at stake if I don't place high enough in the rankings!" Rin's voice cracked. "The bond requires me to stay at the academy. If I'm expelled for poor performance, the dimensional strain will tear me apart. You know this!"
Corvin opened her mouth, then closed it. She did know. They were trapped between impossible choices.
"Then we use what we found in the archives," she said finally. "This morning, the headmaster and I reviewed the sealed research. There's a technique, dangerous and experimental, but it might help. A way to temporarily compress the corruption, push it back for a short time. It won't reverse it, but it could buy you enough time to finish the tournament safely."
"What's the cost?"
"Afterwards, the corruption will accelerate. Whatever percentage you push back will return doubled. But it would give you one clean fight."
Rin processed this. One fight at full power without spreading the corruption further, in exchange for accelerated corruption afterward. It was a gamble.
"There's another option," Kira said quietly. She'd been silent until now, listening. "You could accept Shade's offer. Whatever he's offering might be better than this."
Professor Corvin's head snapped toward her. "You know about Shade?"
"Rin met with him last night. Didn't you?" Kira looked at Rin. "What did he offer?"
All eyes turned to Rin. He thought about the black book hidden under his mattress, about Shade's contract scroll, about fifteen years of research from someone who'd survived what Rin was going through.
"He offered to teach me," Rin said. "In exchange for..."
He explained the deal. When he finished, Professor Corvin looked furious.
"Absolutely not. That man is manipulating you, using your desperation against you. Whatever he wants, it's not your survival."
"But what if it is?" Rin countered. "What if he really does know things you don't?"
The door burst open. A messenger rushed in. "The semifinal brackets are posted. If Rin Eldraven wins his match, he faces..." The messenger swallowed. "He faces Elena Brightstar in the finals."
The room went silent.
Elena. Platinum rank one. The strongest student in the academy.
And her Celestial Guardian was now fully restored and angry.
