I only have this body. I will lose everything if I lose. Everything I built until now will crumble. For someone like me who didn’t inherit the power of destruction, this was the only path for me. That’s why I have to win with my body.

–Sairaorg to Issei during their match, Light Novel Volume 10, Life MAXIMUM VS Power MAXIMUM

Sairaorg Bael is the heir of the Bael Clan. He is the oldest son of Lord Bael and the only child of his first wife Misla Bael, the older half-brother of Magdaran Bael, and the cousin of Rias Gremory and Sirzechs Lucifer. He was known as the strongest young Devil before being beaten by Issei. Due to being the master of Regulus, he is considered the possessor of the Longinus; Regulus Nemea.

His peerage consists of Devils that are scorned by other Devils.


Sairaorg is a handsome young man with black hair and violet eyes. He is very tall and has a muscular build due to the extreme training he has done. Issei notes that his face resembles that of his cousins Rias and Sirzechs. His height is [194 cm] and body weight is [135 kg].


Sairaorg has a noble and calm personality and greatly respects his opponents. He also likes to fight strong people, to the point that Rias Gremory, his own cousin, called him a battle maniac. He is shown to be a kind-hearted and compassionate person and has a very straightforward personality. He even shows unconditional kindness to his estranged half brother. Sairaorg is extremely dedicated to fulfilling his dream to create an Underworld where any Devil regardless of their background can make their dream come true as shown in his unbreakable determination in protecting Auros Academy, which is an important stepping stone to his dream, from Grendel's rampage. Sairaorg takes great pride in his strength and the fact that he trained for it; this is shown when he felt insulted by Bedeze Abaddon's offer to give him a King Piece.

He possesses a great deal of pride and honor as both an heir and warrior, though he does not possess the arrogance that his clan possesses. He is very mature and composed enough to handle things, although he and his mother have been shunned from the rest of his clan due to the abuse that he received from his father and other clan members (not including Zekram Bael).


Born as the eldest son of the Bael Clan, Sairaorg didn’t inherit the Bael's trademark Power of Destruction that Rias and her brother inherited from their mother, who came from the Bael Clan. Because of this, his younger half-brother Magdaran Bael was appointed to become the next heir of the Bael Clan. Sairaorg and his mother, Misla Bael, were then shunned and scorned by the Bael Clan, including his very own father, to the point of being sent to the countryside of the Bael territory.

During his time there, Sairaorg was constantly bullied by other Low and Middle-Class Devils, until Misla advised him to become strong in different ways. Sairaorg then started training his body to its utmost limits to become powerful and due to this, he defeated his younger half-brother, which made him the next heir of the Bael Clan. Sairaorg desires to become Satan to prove his worth even with his lack of special demonic powers.

Sometime before the series, Sairaorg found Regulus, the Lion King, sealed in the Longinus, Regulus Nemea, after its possessor died and it materialized itself. Sairaorg then tamed Regulus and made it his servant through 7 Pawn Evil Pieces.

Powers & Abilities

Lion Tamer: Sairaorg has attributed himself to be able to tame Regulus Nemea due to this trait inherited from his mother; Misla Bael, who hails from the Vapula Clan, which has the power to tame lions.

Touki (闘気, Fighting Spirit): Sairaorg gained enormous touki through intense training, capable of generating wind pressure and a crater merely by releasing it. It strengthens his offense, defense and speed, enabling him to withstand Rossweisse's Norse Magic, Ex-Durandal and the Dragon Blaster. In fact, his powerful life-force allowed his arm to remain after being cut off with Ex-Durandal, instead of vanishing like a normal devil's arm,[1] and allows him to use Breakdown the Beast for short periods.[2]

Immense Strength: Sairaorg developed an extremely powerful body which houses enormous power, becoming the Strongest Youth.[3] He outclassed Zephyrdor, then cracked Issei's armor from the air pressure of his punch alone, then nearly broke through despite a promotion to Rook, earning Ddraig's praise, all while wearing restraints.[4][5] He outclassed Kiba, Xenovia and Rossweisse with ease after releasing touki.[1] He briefly matched Issei in Scale Mail, upon his Queen promotion, before using Regulus and almost killing him with a single punch through his Triana Rook, and then rivaled him in his Crimson Armor, causing earthquakes and cracking the gaming field just from trading blows.[6] Sairaorg wearing his lion armor is strong enough to defeat Ultimate-Class Devils and to fight Grendel, who he launched into the air despite severe injuries from the dragon and a holy relic. [7] Using Breakdown the Beast enabled Sairaorg to brutally overwhelm Bedeze, a Satan-class Devil, and break through his portals while releasing shockwaves over great distances.[8] Issei believes that he can rival or surpass Satan-Class in his Balance Breaker, and that his punches in Imperial Purpure can reach gods;[9] these empowered punches were theorized by Ddraig to rival or surpass the Crimson Blaster, and were even praised by Shiva as "genuine destruction".[10] In this state, Sairaorg could knock back a blast from the Star Blaster, then later defeated Balberith, the strongest of Lilith's Children, albeit the latter was said to have fought half-baked.[11]

Immense Durability: Sairaorg has tremendous, almost ludicrous durability and pain tolerance, taking a straight hits from Issei in Scale Mail, before and after promoting to Rook.[5] He endured multiple attacks from Kiba, Xenovia and Rossweisse, without serious injuries; his arm remained despite being cut off by the two Knights wielding Ex-Durandal, and kept on fighting.[1] Since then, Sairaorg has took on multiple destructive blows from opponents, such as Heracles; the most notable being from Incinerate Anthem and followed by a stomping from Grendel, tossing the latter into the air despite serious injuries.[12] He later withstood his own punch donned in his lion armor, then withstood the strain of Breakdown the Beast, and recovered enough to rejoin the Evil Dragon War. His most notable feats were withstanding blows from the True Longinus and Star Buster Star Blaster, deflecting the latter while using Imperial Purpure.

Immense Endurance: Sairaorg has enormous stamina and endurance accumulated from rigorous training, letting him remain in top condition for extended periods without slowing down.[1] He fought against Issei several times in Scale Mail, Illegal Move Triaina, and Crimson Armor in the Youth Finals, but remained standing even after passing out.[6] Despite taking damage from Incinerate Anthem and Grendel,[12] he mustered enough strength to briefly restrain Grendel and then toss him into the air. Sairaorg endured fighting Bedeze and the backlashes of using Regulus Rey, recovering enough to join the Evil Dragon War. He outlasted Cao Cao in a duel despite being injured from his last battle and concentrated hits from the True Longinus while using Regulus Rey, and kept fighting even after losing his armor.

Immense Speed: He has incredible speed surpassing Kiba, able to appear behind Issei donned in Scale Mail before he could react.

Master Hand-to-Hand Combatant: Through intense training and fighting experience, Sairaorg is an extremely powerful martial arts master, being able to defeat Middle and High-Class Devils.[4][13] Supplemented with his physical strength, his punches and kicks can cause destruction to the surrounding area with the aftershocks of his blows.[5] Sairaorg could outmatch Issei several times in Scale Mail during their initial sparring sessions without using touki or armor himself, then overpowered him using his lion armor before fighting on equal ground in his Crimson Armor.[5][6] He defeated Heracles using little force without his armor, but still destroyed the building behind him. Sairaorg could fight against Cao Cao, who is described as a peerless prodigy in a battle Rias described as being almost god-like.

Extrasensory Perception: On different occasions, he has shown to be capable of sensing things others couldn't like the time he sensed Issei was in the process of an awakening before he and Ddraig were even aware of it. In True Volume 4, Sairaorg sensed that Issei and his powers were different due to his condition of disliking breasts and lewd things, even not seeing him as being the "real" Issei.

Flight: Being a Devil, Sairaorg can fly using his wings.


Regulus Rey Leather Rex

Regulus Nemea (獅子王の戦斧(レグルス・ネメア), Regurusu Nemea): Among the original Thirteen Longinus, housing the spirit of the most powerful Nemean Lion, Regulus, the Lion King. It normally takes form as a golden battle-axe, but currently is able to materialize as a five-meter tall golden lion with a jewel in its forehead. Regulus Nemea is said to boast such power that it can split the earth in half if mastered, and protects its wielder from projectile-based attacks. It's current state is closer to an Independent Avatar; instead of transferring to another host, it manifested to kill the ones who murdered its previous host, and Sairaorg reincarnated him as a Devil. However, since Sairaorg doesn't use weapons, he just uses Regulus Nemea's powers whenever needing Balance Breaker.

  • Regulus Rey Leather Rex (獅子王の剛皮(レグルス・レイ・レザー・レックス), Regurusu Rei Rezā Rekkusu): Sairaorg's Sub-Species Balance Breaker, which creates a golden lion armor whose helm has a golden mane growing from it and a lion's face on his chest. Regulus Rey Leather Rex strengthens his offense and defense to a drastic extent, which allowed him to overpower Issei in his Welsh Draconic Rook, blocking and breaking the armors strongest move, then fought on par with him donned in his Crimson Armor. Sairaorg was able to also fight against Grendel who is known for his strength and defense, then blow away one of his fireballs using his punch.
  • Regulus Rey Leather Rex Imperial Purpure (獅子王の紫金剛皮・覇獣式(レグルス・レイ・レザー・レックス・インペリアル・パーピュア・はじゅうしき), Regurusu Rei Rezā Rekkusu Inperiaru Pāpyua): Regulus Nemea's Breakdown the Beast, which releases the seal on Regulus. In this form, it transforms Sairaorg's lion armor into a more aggressive form with double-toned gold and purple, wrapped in a dense purple (gold) touki. He has tremendous power and speed, letting him overpower the 3rd Ranked, Bedeze Abaddon, an Ultimate-Class Devil, able to rival Satans using the King Piece. Against Cao Cao, Ddraig stated Issei couldn't fight him without Diabolos Dragon, his punches were as strong, if not stronger than Crimson Blaster. Sairaorg tanked slashes from Shooting Star's High-Tier Longinus and knocked back one of his blasts.
