Eld Jinn

Erd Gin (エルド・ジン) was the second-in-command of the handpicked warriors of the Scouting Legion by Levi to be included in the Special Operations Squad.

Personality
Erd was a responsible and firm leader with a strong sense of duty. He did not talk much, but when he did, he talked bluntly and in a straightforward manner. He also seems to have been a Veteran of sorts as he teased Petra Ral and Auruo Bossard about having wet their pants on their first expedition, sarcastically referring to them as "fine fearless soldiers". He also seems to hold some sort of belief of what makes a true soldier, as he lectured Auruo that a kill record alone does not equal to the value of a soldier.

When Eren accidentally transformed, he also seems to have been more concerned about the reasoning as to why demanding an answer from Eren. An interesting reaction in comparison to his comrades as Auruo threatened to kill Eren, Petra fearing for Levi's life, and Gunter demanding evidence Eren is not hostile to them or Humanity.

Along with the other members of the Special Operations Squad, he also showed to have had some remorse over his reaction to Eren when he transformed as he bit his hand just like Eren, symbolizing a bond between them.

On the 57th Expedition, Erd, along with the rest of his squad travel with Eren and vow to protect him. Although they are nearly killed by the Female Titan, the Scouting Legion manages to successfully capture it in a trap. Afterwards, the Special Operations Squad is ordered to standby while efforts are made to capture the human within the Female Titan. However, the operation ends in failure when the Female Titan uses a scream to summon other Titans to her position and is devoured by them.

Afterwards, the squad begins to retreat back to their horses, when a flare leads them off-course. They are then ambushed by a person later revealed to be Annie Leonhardt, who murders Gunter Shulz before transforming back into her Titan form. Eren is ordered to flee while the surviving squad members engage the Titan in battle. Petra and the others initially seem to have the upper hand, Erd launched an attack and smoke screened allowing Petra and Auruo to take out her eyes, then Erd launched several attacks on her arms before Auruo and Petra Joined in making them drop. However as Erd went to srike the neck the Titan regenerated one eye and bit Erd in half.

Death
Erd and Petra move in for the kill, but the Titan suddenly regenerates a single eye and bites Erd in half, also severing his arm.

In the anime, Erd's mother informs his lover that he is returning home from the expedition.

Abilities
Erd was a very skillful warrior who had a very high kill record of 46 Titan kills (of which 32 in team and 14 solo).He also seems to have been very proficient with the Maneuver Gear, using fake outs with the Steel Wires or using the gas exhaustion as Smoke Screen. He was also very quick when slicing the female Titans arms in the Episode: Crushing Blow.
