Sigma Redwing

Sigma usually wears a mask to hide his identity as Phantom Thief Apollon.

He wears stylish, tight-fitting outfits, sometimes described as a blue and black catsuit in later stages.

He has striking violet eyes and is considered especially handsome.

Sigma keeps his mask on almost all the time except for some special occasions.

Sigma is cool and very self-confident, sometimes to the point of arrogance.

He is quiet, usually keeping to himself and not talking much unless needed.

He values his own skills highly, believing few can ever catch him.

Despite being a loner, he helps those in need and has a strong sense of justice.

Sigma is sharp, observant, and always quick-thinking, especially when escaping tricky situations.

Sigma appears mysteriously before Sawyer and proves to be even more agile than him, using wings and gadgets.

He identifies himself as "Phantom Thief Apollon," a modern-day Robin Hood.

He steals from the rich in the White Area and donates to the needy in the Gray Area, always remaining anonymous.

Sigma enters the "Great Mission" in Owari Castle with a hidden goal: to claim "the greatest treasure of the game."

After initially being critical of Sawyer, he gains respect for him and eventually helps both him and other contestants in challenging missions.

Sigma eventually reveals his face around episode 26, showing his violet eyes and stunning looks that even captivate his enemies.

Sigma’s power is his Cry Trigger, "Wraith," which lets him stretch his aura-arm to grab objects from afar or swing through urban landscapes like Spider-Man.

He is equal in agility and parkour to Sawyer.

Sigma is excellent with a sword and can duel famous swordmasters equally.

He combines parkour, gadgets, and strategy to escape tight police cordons or avoid Hunters.

In episode 77, his Wraith is upgraded to allow aura extensions from both hands.

He is Sawyer Tomura’s main rival, and while they argue a lot, they also work together during tough missions.

Sigma eventually grows close to Sawyer’s younger brother Hal after partnering during a revival mission.

He interacts often with Luna Nishinotouin, who calls their constant pairing a “fated connection.”

He saves and later teams up with the journalist Maika Sonjo during the America stage.

• "I won't let even my shadow get caught."
• "Next time, I'll handle all the missions myself."
• "I never asked you to come anyways..."
• "Looks like this is as far as I go..."
• "That guy's (Lamul's) weakness is probably water."
• "It's reassuring to be with a true champion."
• "Go!!"
• "Because your eyes are blue."
• "You're the one who'll be tonight’s dinner!"
• "You probably won't rest in peace until you find out my true identity."

Rival Encounter & The Phantom Thief’s Debut

Sigma appears in "Tousouchuu: Great Mission" during a pursuit as Phantom Thief Apollon, evading police with his skills.

Team-ups, Missions, and Unmasking

At the London Stage, Sigma and Sawyer keep ending up on the same team and sigh about it, even getting teased by Luna.

After Sawyer is captured, Sigma teams up with Hal Tomura and is surprised by Hal’s calmness and skill.

Around episode 26, Sigma finally shows his face–so beautiful that his captor, Medusa, becomes smitten.

Battles with Grace Amber and Ridley Zebbett

In episode 29, during a fight at a dark laboratory, Sigma is injured trying to rescue Grace Amber, who gives him a mission before dying in blue flames.

With Inspector Max Major, he reaches Ridley Zebbett on an airship. Sawyer appears, and despite Sigma's reluctant, they team up.

They steal an ampoule from Zebbett, weaken him, and escape from the airship together.

In the Magic Desert stage, Sigma again acts solo but helps deduce that the sand god Lamul’s weakness is water.

He helps open the gate to the sand temple, holding it so others can enter, showing growing teamwork.

Later, he and Maika work closely as partners during the America stage, escaping in a purple car and passing more missions together.

Casino & Train Missions

In a casino hotel, Sigma disguises himself and leads his team to trick suspects and escape gunfights.

In a train bomb mission, he chooses the red wire based on Maika’s blue eyes, saving everyone.

He joins group quiz challenges in New York and ends up in a confrontation with Samejima, tricks him with a Zeta, and shouts “Go!” to support Rabbit.

Paris Stages & Later Missions

Sigma is captured with Maika by the Phantom Spider but helps save her from danger several times.

He reveals his face to Maika at the Eiffel Tower, saying she cannot rest until his identity is known, and rescues her with his skills.
