Rental Magica

Itsuki arrives late for an appointment at a shrine due to allowing Mikan to buy souvenirs at a festival. The request is from Shinogi Minagi, who requests a saniwa, or spirit medium to convene with Futsunushinokami, the god of the shrine, in order to revive her comatose brother, Moroha Minagi. Although Adilisia and Honami are against Itsuki taking the job, he agrees after seeing Mikan's enthusiasm for doing it. However, as the ritual is being conducted, Kagezaki, a member of the Association, arrives, and tells Astral member Manami Kuroha of Takeminakatanokami, the other god of the shrine. He tells of the incident where Shinogi and Moroha summoned Takeminakatanokami, but Moroha was forced to invoke Futsunushinokami's power to stop him, leaving him in a coma. Mikan, with emotional support from Itsuki and an arrived Honami, manages to seal Takeminakatanokami, and Moroha awakens. On the train back, Kuroha teases Honami for caring about Itsuki and showing up to save him.

Itsuki is in the hospital with a broken leg, where he converses with Manami Kuroha, a ghost inhabiting the hospital. Kuroha is overjoyed that someone can talk with her, and she asks Itsuki about Astral and its workings. Meanwhile, Honami and Nekoyashiki investigate a source of magical pollution near the hospital. Nekoyashiki comes to Itsuki, and dispels a set of bloody hand prints. Honami arrives and the three determine that a dead mage is the cause of the pollution. Elsewhere, Kuroha is consumed by a mass of flesh, and it attacks Itsuki, Honami and Nekoyashiki. They determine it was the result of a mage attempting to acquire immortality by eating souls. As they prepare to destroy it, Itsuki reveals his Glamsight, and the three succeed in rescuing Kuroha. A few days later, with the members of Astral present, Itsuki invites an overjoyed Kuroha into Astral.

Due to the low amounts of jobs Astral has taken since Itsuki took over, Kagezaki threatens to disband Astral if they do not take on a difficult mission. They are assigned to remove the magical pollution creating a vast sea. Goetia arrives as well, and summons a host of birds to attack Honami and Itsuki. Honami dispatches the birds, and Adilisia arrives. However, the sea engulfs Adilisia and Itsuki and then freezes, trapping them. Below the ice, Adilisia reveals that the pollution is caused by a Goetia member that broke a magical taboo, becoming magic, and swears Itsuki to secrecy. The mage is revealed to be Oswald Lenn Mathers, Adilisia's father. He attacks Adilisia and Itsuki, but Honami's arrival saves them. Oswald withdraws and Itsuki makes Honami promise not to reveal the pollution's source before fainting.

Itsuki meets a girl in a park, and seeing her alone, gives her his food and his business card. She later goes to the Astral residence, asking to obtain a basilisk eye, shocking the Astral members. However, with the offer of a valuable gold coin, they accept. They proceed to the basilisk's lair, where the basilisk manages to trap Lapis and Itsuki in a room, and subsequently overwhelms Mikan's protection charm. Itsuki then reveals his Glamsight, and the Astral members dispatch the basilisk. Itsuki then collapses from the magical pollution, and Nekoyashiki barely manages to purify him. Later, Lapis arrives at Itsuki's bedside, and after arguing with Mikan and Honami, who realize she is a homunculus, destroys most of the room in an explosion. Nekoyashiki then realizes that she is being controlled by Yudaikus Tholoide, one of the founders of Astral.

he Astral members go to a hot spring in order to cure Itsuki's eye, as hot springs are situated on magical ley lines, but note that the magic is too weak. They travel up the mountainside, and Kuroha suggests a competition to find a ley line. Honami and Adilisia claim they are above it, but note that they would both want Itsuki's affection as their prize. When the competition starts, Honami and Adilisia try to find the hot spring, tearing the mountain apart in the process. The group then falls into a hole, where they find a rock that is causing the ley line to break. Combining their abilities, they levitate the rock, enabling the hot spring to regain its power. As the members return to the hot spring, Honami and Adilisia's fight causes the fence between the men's and women's baths to break, embarrassing everyone.

Adilisia raids Tholoide's lab, but is defeated by Tholoide and Lapis. Back in Japan, Kagezaki brings an item once owned by Tsukasa Iba, Itsuki's father, that the Association was holding to Itsuki, but reveals that Tholoide is disputing Itsuki's control of Astral. Itsuki and Honami go to a blimp to converse with Lapis, whom Tholoide speaks through. Tholoide concedes the ownership of Astral to Itsuki, but the two agree to battle to determine ownership of the item. After Tholoide claims that Adilisia is dead, Honami attacks Lapis, and Itsuki unveils his Glamsight. Lapis manages to escape, but Tholoide acknowledges Itsuki's power. Later that evening, the Astral mansion is attacked by Lapis, with Nekoyashiki barely managing to create a barrier against the initial assault. Honami flies from the mansion to meet Tholoide, who reveals he is an automaton. He then knocks Honami to the ground with a punch.

Lapis uses her basilisk eye to steal Itsuki's sight, preventing him from using his Glamsight. However, she retreats after Adilisia arrives, and Adilisia dispels Lapis' spell. Elsewhere, Honami awakens in Tholoide's lab surrounded by a barrier, and Tholoide reveals the item the Association was holding was Tsukasa Iba's grimoire. Itsuki plans an assault on Tholoide's headquarters, and Honami, realizing Itsuki is coming, desperately tries to break the barrier using a spell with her blood, but Adilisia's arrival makes it unnecessary. Itsuki confronts Tholoide, who easily defeats the Astral members with the basilisk eye he took from Lapis. Honami and Adilisia arrive, and Tholoide transforms Lapis into a basilisk to fight them. Itsuki manages to resist the eye's effect, revealing his Glamsight. He frees Lapis, telling Tholoide that as president, he can only aspire to be the best he can.

He tries to take the flower, but Honami takes it, escaping with Itsuki, leaving Kuroha behind. Itsuki resolves to save Kuroha and retain the flower for Diana. Elsewhere, Diana approaches Chen, regretful that she sold him the root for the flower, as he killed a village to seed it with power.

Kei remarks that he lost his sister, Sakuya Isurugi during a similar ceremony three years prior because Nekoyashiki left the school at the time to take Mikan to Astral. Nekoyashiki challenges Kei to a personal duel, and Itsuki upholds this, stopping the arriving Honami and Adilisia from interfering.
