Marin Hollow

Marin Hollow (マリン・ホーロウ Marin Hōrō) is a soldier in the Alvarez Empire's Imperial Army, and a part of Brandish Squad, that serves directly under the Shield of Spriggan, Brandish μ.

Appearance
Marin is a thin, young man of average height with spiky, dark-colored hair. He wears dark-colored trousers and a dark-colored blazer, both of which have plaid designs on their outer linings. Underneath his blazer, he has a light-colored shirt with a large collar that he kept upturned. In addition to this, he sports a striped bandanna and a pair of glasses on his forehead.

Personality
Marin is a very jovial individual, often smiling and complimenting others, particularly women. However, this happy disposition immediately flips into one of anger and disgust when Marin is around people he deems to be unworthy. Sometimes, he will judge people based on their looks, often females, but immediately start despising people who annoy him, those often being other men.

As he considers himself to be a master of Spatial Magic, this anger is usually directed at those who believe they can out-play him in his element. The polar nature of his personality shocked both Natsu and Gray, who witnessed first-hand Marin flipping between a polite and insulting disposition.

Alvarez Empire arc
Marin arrives at Caracole Island and destroys a gelato shop where Team Natsu is eating. He emerges from the rubble, and introduces himself as a member of the Alvarez Empire's Brandish Squad, Marin. Erza, enraged that the dessert stand was blown up, attempts to Requip to attack him, but Marin reveals that he has blocked off her Magic, as his own revolves around the manipulation of space. Lucy, trying to aid Erza, goes to summon a Celestial Spirit, though Marin blocks her Magic too due to its spatial relation. Smiling at the two, Marin then reveals he has his own special space reserved for those who break his rules, and spirits Lucy and Erza away in a cloud of smoke.

Seeing their comrades disappear, Natsu and Gray ask Marin where he sent them. Marin replies that Lucy and Erza passed the test and as a result were sent to his relaxation dimension, but angrily tells Natsu and Gray that they didn't pass. At that moment, he drops an injured Mest in front of them and says that he didn't pass the test either. Natsu and Gray then angrily try to attack Marin, but he gets the best of them with his Spatial Magic. Before their battle can continue any further, however, Brandish appears and Marin apologizes to her for his reckless actions. She asks for some star mango gelato, and upon seeing the destroyed stand, Marin blames Natsu and Gray for it. Prompting to leave out of disappointment, Brandish expresses her disinterest in the fact that Fairy Tail attacked their soldiers, much to Marin's dismay. He tries to push the subject further, which causes Brandish to use her Magic, making the island drastically emerge from the ocean. Marin is terrified by her power, and thus returns Lucy and Erza as she commanded. Natsu confronts the duo over an injured Mest, and Brandish appears to disintegrate Marin with her Magic to make them "equal", leaving no trace of him, much to Fairy Tail's surprise and disgust.

However, it turns out that Brandish simply used her Magic to make Marin too small to be detected with the naked eye as a way of fooling Fairy Tail into backing off. The two return to Zeref's castle in Vistarion. Left in a miniature state, with Brandish not being in the mood to undo her Magic, Marin compliments a gloomy Brandish as she lounges in her quarters, reading a magazine. He then nervously requests to be returned to his normal size as he paints her toenails. Right at that moment, Dimaria Yesta enters the doorway and chides Brandish for letting Fairy Tail escape, Brandish replying that she didn't let them escape, but rather simply didn't bother to stop them. Marin sheepishly mentions that he had tried to reason with Brandish and pays a compliment to Dimaria as well, with the latter asking Brandish to restore Marin back to normal due to being rather disgusted by his current form; she also reminds Brandish that the Spriggan Twelve were summoned, and tells her to bring Marin along. As she leaves, an annoyed Brandish scoops Marin up between her toes and brings him close to an eye level, expressing her dislike towards Dimaria, with Marin only being at the mercy of Brandish's unenthusiastic attitude. Later, at night, while the Alvarez Empire makes their move and invades Magnolia, Marin, still in his miniaturized state, intrudes Lucy's bathroom alongside Brandish. As Lucy walks in on the two, expressing the utmost shock to see Brandish bathing in her tub, Marin shouts out that her house gets a pass.

Marin is quickly, however, taken by Brandish and shoved into a bottle, as she believes that his presence is causing Lucy to be too reluctant to get into the bath with her. When Lucy finally relents and gets into the bathtub, Marin shouts from the bottle that he wants to get in the tub as well. As the two women stare each other down inside the tub, Marin squeaks for Brandish to release him from the bottle, but to no avail, as his superior ignores his cries completely. When the two women then start to converse, with Lucy washing Brandish's back, Marin remarks that that is normally his job, yet again asking to be let out in order to fulfill his duty. As Brandish realizes that Lucy is the daughter of Layla Heartfilia, she shrinks Lucy's house into a miniature shape; although Lucy manages to escape, having taken the flask which Marin is trapped in with her. She triumphantly holds the bottle up to the sky, before letting it go, hurling her foot at it as it hits the ground; the bottle shatters and Marin, having been stomped upon, is rendered out of commission.

Later, a now normal-sized Marin locates Fairy Tail's guild hall where Brandish is being held captive, awaiting to start his infiltration. An opportunity soon presents itself and the manipulator of space immediately teleports himself into the Guild's dungeon, right into his master's cell. Delighted to see the woman, he greets her with a fresh smile; however, as soon as the Shield of Spriggan orders her pet to relieve her of her bonds, Marin's demeanor changes completely and the man feverishly grabs hold of the prisoner's neck. As he throttles her, the Mage condemns her for the maltreatment he has suffered under her and swears revenge. Helpless due to her restraints, Brandish is unable to stop her subordinate from slowly choking out her life.

Magic & Abilities
Spatial Magic (空間魔法 Kūkan Mahō): Marin is a very adept user of Spatial Magic, which revolves around the manipulation of space. This Magic allows Marin to teleport himself instantaneously to any location he desires. His teleportation is so fast that neither Natsu Dragneel nor Gray Fullbuster were able to actively land a blow on him during their short bout. His Magic also grants him the ability to cancel out any Magic relating to space, an ability he used to stop Erza Scarlet's Requip, Lucy Heartfilia's Celestial Spirit Magic, and Mest Gryder's Teleportation Magic. It can also be used to send other people who have violated what he refers to as his "law of space" to an alternate dimension.
