Invel Yura

Invel (インベル Inberu) is part of the Alvarez Empire as one of the Spriggan 12, the protection guard of Emperor Spriggan. He is the emissary of Alvarez, serving as the Emperor's chief of staff and consul. His epithet within the Empire is the "Winter General" (冬将軍 Fuyu Shōgun) due to his cunning use of Ice Magic.

Appearance
Invel is a bespectacled man of average height. Most of his long, white hair is bunched into a ponytail by a golden brace. The ponytail hangs past his right shoulder, reaching up to his chest. The rest of his hair is quite messy, with uneven bangs falling down the sides of his face and between his eyes. He has alert eyes with red irises. His attire is quite trim, befitting his strict personality. It comprises of a simple pair of dark dress pants and a white collared dress shirt, completely buttoned up and with a blue tie hanging from the neck. Over this, he dons a trench coat with a white border. The color of its interior as well as its exterior matches that of his tie. Dark markings are diagonally branded from the left shoulder and sleeve and run down the front and the back of the coat. The coat has a high collar which is left unfolded. The cuffs are also quite large. As the coat cannot be closed down the front, Invel fastens it with a long belt, looping it twice around his waist and then holding it fast with a simple buckle. This leaves part of the front of his shirt exposed, allowing the tie to be tucked neatly into the coat. The belt itself has a pattern of diamonds running across it. His outfit is completed by a pair of dark shoes with contrasting light soles.

Personality
Invel appears to be a stern individual who values order and respect. Due to this militaristic nature, while he is careful not to overstep his own bounds, he clearly voices his displeasure in case the actions of any of his associates are deemed to be out of keeping with their position in the Empire, be it another Shield of Spriggan or the emperor himself. He is also a highly capable orator and leader of soldiers. Quite close to the emperor, he reveres him greatly, chastising even his colleagues if he perceives their actions towards their sovereign to be disrespectful.

Alvarez Empire arc
Invel greets Zeref as he returns to his palace in Vistarion. Asked about gathering the Spriggan 12, he says that it will take some time for the twelve to heed the call. As Ajeel Ramal and Dimaria Yesta appear, Invel reprimands them for their behavior in the presence of the emperor, as well as Yajeel about the official documents that allow a foreigner to get an audience, but Zeref dismisses it as unnecessary. As Yajeel asks Zeref to have an audience with Makarov Dreyar, Invel and his fellow Spriggan 12 members leave upon Zeref's request. Later, when Zeref calls a meeting for his Shields, Invel attends and is upset that Neinhart ignored Zeref's summons. He then listens as Zeref spells out the upcoming war against Ishgar.

As the war against Ishgar proceeds, Invel escorts Zeref, who is leading a part of the Empire's army. As they approach Magnolia from the west, the Invel reports the defeat of their vanguard and expresses his disbelief at the outcome. He later informs the emperor of an unidentified object hurling straight toward their location, accompanying his lord when they head out to confront the enemy, Natsu. While Natsu and Zeref converse, Invel calms down the troops who question the enemy's constant reference to their emperor as "Zeref" by revealing it to be Spriggan's true identity. When ordered to retreat so that Zeref and Natsu might fight freely, he reproaches his master for attending to such a trivial matter, but obeys nonetheless, Although concerned for his emperor's safety throughout the course of the battle, he restrains himself from interfering, and, subsequent to the Fairy Tail Mage's retreat, carries out Zeref's orders of fetching him imperial garments as well as having the troops resume their march towards Magnolia, warning them not to underestimate their opponent as well as alleviating their anxieties regarding the defeat of five Shields of Spriggan by delivering a rousing speech. As the army proceeds towards Magnolia in an orderly manner, Invel suddenly notices that Zeref is worried about something and enquires about the source of his concern, only to be vaguely informed that the nature of the Magic flowing through the land has been changed by Irene.

In the aftermath of the casting of Universe One, Invel rejoins Zeref in the Fairy Tail Guild hall, finding Zeref in conversation with Mavis, whom he instantaneously freezes in order to contain the power of Fairy Heart. However, at his emperor's behest, he frees the maiden, but retains an iron grip over her very thought processes. The Winter General then reunites with his fellow Shields of Spriggan as they await the arrival of their enemies and the liberation of Fairy Heart from Mavis' body.
