Lahar

Lahar is the Head of the 4th Custody Enforcement Unit under the newly reformed Magic Council, following the events of the Tower of Heaven arc.

Appearance
Lahar is a slim man of average height with long black hair, tied in a large bun on the back of his head, with two bangs framing his face and an unruly tuft covering his forehead. He has prominent cheeckbones, and wears a pair of glasses with circular, elongated lenses.

His attire is that of a high-ranking Council's associate, consisting of a long, bluish jacket, with pinkish edges and straps on the cuffs, over a high-collared shirt bearing the Council's signature ankh-like symbol, white pants held up by a simple belt, white gloves, a white cape held closed by a buckle decorated by a large gem, and distinctive shoes, seemingly bearing a snake pattern.

Personality
Lahar is strict, firm, and unbending in his beliefs. He takes his job seriously, and believes that anyone who has committed a crime is a felon, and must be brought to justice. He does not care even if a person that once was bad has become good, sticking to the Council's rules in relation to it.

Despite his strict personality, Lahar allowed Jellal Fernandes to bid farewell to his comrades, even encouraging him to tell everything he had to, due to the strict sentence awaiting for him, and didn't take any action to arrest them when they attacked his Rune Knights, after Erza Scarlet took all of the deed's responsibility on herself. Not only that, but he showed extreme care to his comrades when they were injured in the Council ship's explosion, ordering them to be treated before any repair to the ship's facilities.

Oración Seis arc
Lahar appears and places the Light Team in a Magic barrier in order to prevent them from leaving after they destroy Nirvana. Having introduced himself, Lahar takes Hoteye into custody and attempts to take Jellal Fernandes as well, not caring that he has turned good or helped stop the Oración Seis. As Natsu Dragneel and the rest of the Light Team try to stop such senseless cruelty, Lahar places them all under arrest. However, Erza Scarlet's pleas allow him to renounce his order. He leaves, and later arrests the rest of the Oración Seis.

S-Class Trial arc
While Fairy Tail is gathered on Tenrou Island, a ship from the Magic Council is revealed to be anchored nearby, to control them, with a Mage under the Council itself, Doranbolt aka Mest Gryder, having infiltrated the guild itself. However, all of them are unaware that Fairy Tail is the target of the Dark Guild Grimoire Heart. As Doranbolt, having gotten wind of that, declare all of the Dark Guil's members under arrest and reveals the ship's presence, one of Grimoire Heart's Seven Kin of Purgatory, Azuma, blows the ship up from afar with his Great Tree Arc Magic before the astonished eyes of Doranbolt, Wendy Marvell, Pantherlily and Charle.

Lahar first appears on the very same, heavily-damaged ship that Azuma attacked, being revealed to be the one in charge of it. He tells his men to treat the wounded before thinking about the ship's facilities, and announces they'll attack the island, when Doranbolt teleports to his spot. The infiltrated agent informs him that Grimoire Heart, Zeref, and Fairy Tail are all on Tenrou Island, shocking him and giving him chills. Lahar then coldly murmurs about how Guran Doma, the chairman of the Magic Council, would not hesitate to fire Etherion, in order to take care of the matter. When Doranbolt protests to this, Lahar says that it's not for them to decide what to do, and tells him to inform the HQ.

The two of them are then shown discussing about Bluenote Stinger, revealed to be a member of Grimoire Heart. Believing that, with the man on the island, things just look worse, Lahar readies to contact the HQ through the use of a Communication lacrima. However, he's stopped by Doranbolt, who, asking him for some more time, teleports away with the lacrima, preventing him from using it. Lahar wonders what Doranbolt is planning to do.

A shaken Doranbolt later returns to the ship, and informs Lahar that Zeref has started using Acnologia, seemingly a fearful and infamous Magic, as Lahar is seen shaking himself and sweating, and then orders his men to retreat in a hurry, stating that the investigation of Tenrou Island is over.

Magic & Abilities
Jutsu Shiki (術式 Jutsu Shiki): Nothing is known about Lahar's Magic, but he was apparently the one behind the creation of the Magical barrier which was used to surround the Light Team. If he really was the author of such spell, his Magic seems to work in a similar manner to Freed Justine's.
