Sairaorg Bael

**Regulus Rey Leather Rex**, also known as the **Iron Skin of the Lion King**, is the sub-species Balance Breaker of the Longinus Sacred Gear; Regulus Nemea. It is achieved when the lion sealed inside Regulus Nemea; Regulus, combines with his master; Sairaorg Bael.

## Summary

In Volume 10, during his fight with Issei, Regulus asked Sairaorg to combine with him, stating that with their Balance Breaker, Sairaorg would easily win against Issei, though Sairaorg refused as he swore to only use it in the defense of the Underworld. However, due to being moved by Issei's determination to fight him with everything he had, Sairaorg combined with Regulus into this form, as he overwhelmed Issei's Triana Rook form and incapacitated Issei with a punch, rendering his unconscious. Sairaorg later fought Issei, who had unlocked his Crimson Armor, with Sairaorg losing as he was knocked unconscious while still standing up.

## Abilities

**Regulus Rey Leather Rex** is a armor-type Balance Breaker, similar to Scale Mail. It drastically increasing the user's power, abilities, speed, and defense while channeling the earth-breaking power of Regulus Nemea through the user's fists. The armor is also capable of repairing itself from almost any damage it takes. The punches can generate a aftershock pressure wave which can be used as a ranged attack.

When Sairaorg used this form against Issei Hyoudou, he was able to completely overpower Issei in his Welsh Dragonic Rook form, blocking Issei's *Solid Impact* attack as he crushed the large fist and as he punched Issei, easily destroying his armor and made him spit out blood, knocking him unconscious. After Issei attained Cardinal Crimson Promotion, Sairaorg was able to fight with him equally.

Sairaorg used this form to fight against the legendary Evil Dragon Grendel, as he was capable of fighting equally against him, with Grendel praising his power as most of Grendel's opponents aren't strong enough to fight him head on.

Saiorarg used this form to easily defeat Heracles in their rematch, despite Heracles training and putting up a far better fight then last time.

The armor also increases the wielders defensive ability especially against projectiles and ranged attacks. Sairaorg was able to withstand Crimson Armor Issei's *Crimson Blaster*finishing attack, which have been shown to be able to kill Ultimate-class Devils like Shalba Beelzebub. It was also shown to be able to shield the user against Incinerate Anthem's flames, as shown when a wounded Sairaorg was able to survive being hit by them despite the flames power to easily destroy Devils.

## Chants

To activate his Balance Breaker, Sairaorg performs the following chant:

* English
* Kana
* Romaji

My lion! King of Nemea! You, who has been called King of Lions! Answer my howl and turn into my armor!

我が獅子よ!　ネメアの王よ! 獅子王と呼ばれた汝よ!　我が猛りに応じて、衣と化せ!

Waga shishi yo! Nemea no ō yo! Shishiō to yoba reta nanji yo! Waga takeri ni ōjite, i to kase!
After which Regulus combines with him, as the both of them exclaim **"Balance Break!"**

## Trivia

* Regulus Rey Leather Rex is considered a **Crest Side**Balance Breaker, due to being a subspecies.
