Ludis Mergas (Kor. 루디스 메르가스) is a Noble and one of the eight current Clan Leaders of Lukedonia. He is the leader of the House of Mergas and the Guardian of Lukedonia - the one in charge of its security and protection.


Like all nobles he has a beautiful face with red eyes. He has gray hair which covers his right eye completely and is seen wearing a noble attire like all pure-bloods. Despite his rank and displayed abilities, Ludis seems remarkably younger in appearance than other clan leaders, being called a "kid" by a crew member of the 8th Fleet.


Ludis and his clan are kind to humans. This is seen when Tao, Takeo and M-21 are treated well after their crash landing in Ludis's territory. However, when he hears about intruders, he assumes there might be a connection between the plane crash and the intruders and so sends for the central order to check on the survivors.

Ludis is generally calm, patient, polite, and kindhearted to his comrades, but is cold and doesn't hesitate to get rid of his enemies. He is extremely loyal to the Lord and Lukedonia; when ordered by the former to show the Union "the price they must pay" for attacking Lukedonia, he annihilates the fleet without mercy. However, he seems to be mostly nonviolent and has the highest tolerance for annoyances, as seen how he puts up with Karias while the other Clan Leaders are quick to get angry with him.

Ludis has shown respect towards Gejutel despite the fact that the Lord has suspicions about Gejutel. He even reminds the Lord about Gejutel's reputation of being loyal during her father's reign.


It is revealed by Raizel that Ludis' role is to be the Guardian and Shield of the Lord.[1] Later during the humans' attack on Lukedonia, the Lord claims Ludis' title is the Guardian of Lukedonia.

Ludis is in command of the Central Order. So far the Central Order has been reporting to and receiving orders from Ludis only. He is the one who sent reinforcements and ordered to take more extreme measures and allowed their use of weapons. In chapter 376, Gradeus suspects that Ludis is the one in charge of the Central Order. He is also the one to receive orders regarding the Central Order from the Lord.

Plot Overview

Volume 3

Lukedonia Arc

Ludis is first shown in the assembly of clan leaders, summoned by the Lord shortly after the 500th anniversary of the previous Lord. It is to hear the report of Rael and Seira about the existence of man-made humans and an unidentified troublemaker in the vicinity of Seira and Regis' mission base.
After Frankenstein's plane crashed into Ludis' territory, his men takes care of the survivors. It is assumed that the forbidden region where Rai's mansion happens to be, is also situated somewhere near his land. So he is informed about the intruders in there. After hearing the news, he doesn't lose time to investigate and takes steps to round up the intruders. However the troops of Central Order he sends, failed to carry out the mission. So, he informs the Lord about the situation, seeking her permission to enter the forbidden region. But the Lord sends Rajak and Karias to capture the intruders instead.

Identity Arc

Ludis is seen to assist to execution of Gejutel which, however, is interrupted by the arrival of Rai. As soon as Kaye is overwhelmed by mind control of Rai after trying to stop him on order of the Lord, he tries to help Kaye but also he is immediately overwhelmed by the mind control of Rai. During Rai's duel with Raskreia, he is told to fulfill his duties as the shield of Lukedonia. He uses Izarok to create a barrier to protect the shrine while the two most powerful blood governors clash with each other. He is assisted by Rozaria in strengthening the barrier. However, his barrier shatters once Raskreia summons all her power to make the final powerful blood field that even Rai comments he couldn't face head-on.
After the identity of Rai and wish of the previous Lord are brought to light, all the misunderstandings are cleared. However, the former clash has rendered Lukedonia temporarily visible and the 8th fleet grabs the chance of attacking Lukedonia. The Central Order Knights on border duty fail to prevent the attack and Ludis steps in to check on what's happening. He annihilates the 8th fleet under an hour. Later the fleeing enemy who has entered the Noblesse's mansion are also round up.

Soul Weapon

Ludis ch193 p07

Soul Weapon

Izarok: Ludis' Soul Weapon takes the form of a sword and shield. The shield glows with a green aura and is able to withstand the powerful blood field exchanges between the Lord and Cadis Etrama di Raizel. Ludis can use the shield to set up a powerful barrier. While being a mostly defensive Soul Weapon, the sword is sharp enough to cleave a military ship in half with a single blow.  

Aura Manipulation

Ludis can create a unique three-dimensional force field from his aura. It was strong enough to easily block an assault of  naval gunfire like it was nothing. Ludis can form a barrier made up of titanic golden crosses. This barrier entombs and seals away its target for eternity. However, this is the last resort for Ludis, as this art requires Ludis' life force to create and complete. The aura manipulation also enables him to control enemy attacks to some extent. During the battle between Rozaria and the traitor clan leaders, Ludis uses this power on the enemy attacks which are directed at Rozaria, to turn towards him instead.
