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.

Personality
Strict to the letter and, at best, an unmovable pivot in the eyes of the law, Lahar takes his job seriously, even if it goes too far. He sees 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, since he will make good people suffer to catch villains.

Although he has a his strict personality, Lahar arguably has a kind enough heart enough to let Jellal Fernandes say a farewell to his comrades, and to not take any action to arrest them when they attacked Rahal's Rune Knights. Not only that but he showed extreme care to his comrades when they were injured in the ship's explosion. But he showed uncaring toward the Fairy Tail Guild members when he surmised that they would be killed in the Council's attack to crush Grimoire Heart and Zeref.

Oración Seis Arc
Lahar appears and places the Light Team in a magic barrier in order to hold them after they destroy Nirvana. After introducing himself, Lahar takes Hoteye into custody and attempts to take Jellal as well, not caring that he has turned good or helped stop the Oración Seis Guild. 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
Lahar appears again in the S-Class Trial Arc on the heavily-damaged Magic Council ship that Azuma attacked. He tells his men to treat the wounded and to prepare to charge into battle when Mest Gryder teleports to his spot. Mest informs him that Grimoire Heart, Zeref, and Fairy Tail are all on Tenrou Island, giving him chills. Lahar then coldly murmurs about how Guran Doma, the chairman of the Magic Council, would not hesitate in firing Etherion. But when Mest protests to this, Lahar says that its not for them to decide what to do and tells him to inform the HQ.

Magic & Abilities
Nothing is known about Rahal's magic but apparently he can create magical barriers like enchancements to restrain people in a similar manner to Freed Justine.
