Relic

*For the remains of saints, see Saint.*

The **"Relic"** (遺産（レリック）, *Isan (Rerikku)*?, lit. "legacy/heritage") refers to an object, or more actually a pair of objects, connected to a past Level 5 and Academy City's "previous generation".

## Etymology

In a religious sense, a relic (derived from the Latin *reliquiae*, meaning "remains") is an object or article of religious significance from the past, such as the physical remains or personal effects of a saint or other similarly venerated person, preserved for veneration as a tangible memorial. Relics are present in Christianity, Buddhism and various other religions. A shrine housing one or more religious relics is known as a reliquary.

The term can also refer to something which has survived the passage of time, such as an object or custom whose original culture has disappeared, as well as an object cherished for historical or memorial value (such as a keepsake or heirloom).

## Principles

There are numerous rumors surrounding the Relic, said to have leaked from a now-defunct laboratory. It has been said to be a malignant tumor which consumes esper powers, a precious stone which gathers lifeforce, or a secret technique to rearrange the "braid of time".

Tokiwadai Middle School also has a rumor concerning a "Relic", specifically rumored secret win condition for its student council presidential election, outside the election itself - a treasure hidden in Tokiwadai which is said to give each president a hidden power, with people relying on the rumor called **Diggers** (伝説探し（ディガー）, *Densetsusagashi (Digā)*?).

### Relics

The actual Relic (or rather Relics, given that there are at least a pair of them) is a **cube** (立方体（キューブ）, *Rippōtai (Kyūbu)*?), which is connected to one of Academy City's past Level 5s and the city's mysterious "past generation".

At the time of the events surrounding Tokiwadai's Student Council Election, one Relic was in Tokiwadai, held by Kokuchou Mayui, while the other was in a facility which Kouzaku Mitori infiltrated, with that Relic subsequently making contact with her.

Created through the former Level 5's Synthesize Grid, the Relics are capable of manipulating those who hold them, apparently putting them under the influence of the former #1, and allow them to draw upon powers associated with them. Aside from through a host, the Relics can communicate through metal vibrations. Kouzaku's Relic initially contacted her in this way, and later received a speaker platform attachment to convert the vibrations into a voice, created by Kobayashi Satori after Iori Mashiro decoded its frequency.

* The Relic in the shape of a cube
* The Relic taking an orb shape in Iori Mashiro's hands
* The Relic in the shape of a bar, in Shokuhou Misaki's bag
1/3
While normally cubes, the Relics are capable of changing their shape. The Relic which Kouzaku found could change shape into an orb or a bar, while the Relic in Kokuchou's hands could disguise itself as a book.

### Synthesize Grid

* The Relic-influenced Kokuchou invoking Synthesize Grid.
* The Relic-influenced Kouzaku invoking Absolute Leaf.
1/2
The ability possessed by the former #1 Level 5 and used through the Relics is known as **Synthesize Grid** (万能結晶（シンセサイズグリッド）, *Ban'nō Kesshō (Shinsesaizu Guriddo)*?, lit. "Multi-purpose Crystallization"). Kouzaku's Relic referred to their power as **Absolute Leaf** (支配箔化（アブソリュートリーフ）, *Shihai Haku-ka (Abusoryūtorīfu)*?, lit. "Dominating Leaf-making"), but later confirmed Synthesize Grid and Absolute Leaf were the same power and they only used the different name to distinguish between them and their counterpart. Kokuchou's Relic invoked Synthesize Grid with the command **Drive** (輪転（ドライブ）, *Rinten (Doraibu)*?, lit. "Rotation"), while Kouzaku's Relic invoked Absolute Leaf with the command **Throttle** (流転（スロットル）, *Ruten (Surottoru)*?).

According to Kouzaku's Relic, Synthesize Grid allows its user to control the **Starting Crystal** (始点の結晶, *Shiten no Kesshō*?, lit. "Starting Point Crystal"), described as being at base of all crystals and possessing incomparable bonding power. Growing from the small metal particles used as a core, the Synthesize Grid's influence can enter apparently all forms of matter to transform and control them, described as practically taking control of the entire space around the user. In addition to consuming and controlling, if the all-purpose crystal grows, it can also create new matter, hence its name.

Quite prominently, Synthesize Grid is capable of consuming esper powers within its area of effect, manifesting Shadow Metal as a result. This has mainly been seen with deliberately exerted power, but given the Relic's comments about consuming the supernatural as they wandered the city's skies and other usage, this may extend to ambient traces in the surroundings. Besides Shadow Metal, not naturally-existing and not creatable through a particle accelerator, the Relic said that it could theoretically create fictional metals like orichalcum or hihiirokane.

The nanometal particles, spread through Synthesize Grid's area of effect, act as a medium for the thoughts of the user and are remotely controlled, either directly or on auto-pilot, being used to cause various phenomena within the territory they fill. The influence of the power is, at times, visually represented in the form of a dark miasma.

One prominent effect which heralds Synthesize Grid is a drop in temperature, producing a "chill" within its territory, to the extent of ice forming. As with other matter affected by Synthesize Grid, due to the nanometal and the metallic bond are the core of the power, the ice produced by the power is somewhat silver and has a metallic luster. The nanometal particles are capable of transforming the air and absorbing energy to steal heat, freezing and weakening individuals through hypoxia. They can also manipulate structures formed from the produced ice, such as launching icicles formed from frozen water balls.

* Carbon blocks placed in walls, seen by the diving Tatsuki Mirei.
* The scene of a Synthesize Grid attack on Mikoto being shattered.

The power of Kokuchou's Relic was able to considerable bolster her own ability, allowing her to produce cuboid barriers which can seal off a target area, trapping or protecting individuals within, with a nosebleed following its use on a couple of occasions. Among other phenomena produced by Kokuchou's Relic with the power, there was an invisible attack from the nanometal particles capable of disintegrating and easily boring a large hole through multiple large objects (similar to or possibly Mimosa, given the other Relic's comments), and the formation of carbon blocks within structures. In the case of Kouzaku's Relic, it was able to neutralize an effect caused by the other Relic (namely the manifestation of large metallic spikes to skewer Misaka Mikoto when she strongly invoked her own power), with the effect of the scene shattering.

* A winged shadow over Kokuchou.
* A red aurora and miasma manifesting behind Kokuchou.
* Insectoid limbs manifesting on Kouzaku's back.
1/3
Another phenomena displayed with Kokuchou's Relic is an unknown red aurora, accompanying the dark miasma emanating from the host's back in a manner similar to butterfly wings. Similarly, Kouzaku's Relic was capable of manifesting three vaguely-insectoid limbs from the right side of its host's back.

* A spatial warp created from a clash between the Relics.
* A glimpse of the Imaginary Number District.
1/2
A clash between the powers of the two Relics produced a spatial warp at the point of the clash, with a nearby observer witnessing glimpses of the Imaginary Number District. Kouzaku's Relic later said that their power shouldn't be able to pry open dimensions and they couldn't explain that 'strange view', wondering if their counterpart had developed while they were wandering or whether they merely didn't remember.

### Previous Generation

Not much is known about the unnamed Level 5 behind the Relics. When communicating with Kouzaku, they claimed to be her **"Senior"** (先輩（シニア）, *Senpai (Shinia)*?) academically and the previous #1 Level 5. During a conversation with Kobayashi Satori and Iori Mashiro, they talked about making Bank requests over a phone line charging every 10 seconds and watching images loading line by line on a CRT monitor, with it taking over a minute for a page to display. In discussion after Shokuhou awakened, besides their former status and ability, they claimed not to remember their name or how they ended up in their disembodied state, though the few fragments of memory they retained suggested that Aleister Crowley and Kihara Noukan were involved in their original body's destruction. They described themselves as wandering the skies of Academy City and devouring the supernatural as they did, until a powerful clash during the Daihaseisai allowed them to be reborn into the physical world, fashioning their current vessel via their ability. Kamino later described them as a born esper, a Gemstone, who had come from outside the city and rose to #1, with research on them greatly contributing to esper development techniques and forming the foundation for the current generation.

There were differences between the wills in the two Relics, with the former Level 5's mind having apparently been split, and returning from wandering at different times. With Kokuchou's Relic, on taking over when Misaka Mikoto approached, they said a current Level 5 should stopped by the previous. They also expressed a wish for revenge and intent to bring down the hammer and destruction upon the city's law and its ruler. They were initially unaware of the other Relic and its similar power, later describing it as its copy. The Relic in Kouzaku's hands intend to stop its counterpart's plots, describing itself as the same as the other and it itself as its own greatest enemy, as well as accepting the 'humiliation' of returning to a world it considered hellish to do so. In response to its counterpart's 'arrogance' towards its copy, it claimed that people evolved by copying and there was nothing to say a successor was inferior to the original.

Aside from the Level 5, there is also another group associated with the Relics who are also said to be part of the mysterious and rarely mentioned "previous generation" before the current generation. This group used two squares (visual representations of the cubes) as their symbol. Aside from the Relic, the group also sought Shadow Metal, said to exist as cubic crystals, with an increase in activity after a large amount was generated in an event during the Daihaseisai. The group had a number of facilities and personnel at their disposal.

According to Kamino, they originated as a group of researchers who studied the former #1 and came to worship him. After they were split into two cubes, the scientists with those ideals and goals adopted the two squares as their symbol and the name **□□**, camouflage for inconspicuousness. □□'s current goal is apparently to create a new body for the former #1. Using a genetic sample from their remains, a test tube baby was created to act as a vessel (referred to as the **true body** (真体, *Shintai*?)) and given to surrogates to raise. Kamino and Shokuhou theorized that this child was Kokuchou Mayui.

1/3
A schism in the group later led to a portion of them breaking off to form the **Kaisei Corporation** (回生コーポレーション, *Kaisei Kōporēshon}*?, lit. "Regeneration Corporation") (**KSC** for short), which would become Academy City's top company in the field of regenerative medicine. The company's logo (⧈) is also made up of two squares, but with one inside the other rather than side-by-side. They are in possession of the former #1's remains - an arm rising up from a mass of cubes.

### Other

* Kamino, with her square-shaped eyes.
* Kamino's ability, with its cube-shape, disintegrating Kumamori's cube.
* Kamino focusing her ability.
* Visualization of Kamino's "area" teleportation.
1/4
Aside from the two with the Relics in hand, one of the other election candidates who was involved and emphasized in the events surrounding the election and the cubes, possesses traits notably similar to the Relics and their associated aspects.

Kamino appeared to have square-shaped eyes (somewhat similar to the square representation used by the group connected to the cubes) and used a spatial ability affecting a cube-shaped area, capable of disintegrating objects within a designated area. At the time of the ambush, Kamino was targeting the building in which Shokuhou was trapped with her ability. At the same time, in the sealed off space (with a cube-shaped barrier in place), Shokuhou was feeling effects reminding her of the past Level 5 (with the effect represented visually with a dark miasma), however much of this was actually the result of the power exerted by the Relic. Kamino's square eyes were actually the result of her wearing contacts to support her true ability, a form of "area" teleportation that allows her to transfer targets between designated areas within her line of sight. The contacts have a sight drawn on them to measure out and designate a box-shaped teleportation field, while the "matter annihilation" erroneously recorded as her esper power is a result of a failed teleportation when she loses sight of the destination.

However, after revealing this while saving Shokuhou Misaki, Kamino displayed knowledge of circumstances surrounding the cube, saying she would tell Shokuhou about the previous generation and "**□□**" once she recovered. She turned out to be connected to the Kaisei Corporation, who had funded some of her experiments, and was apparently performing an undercover investigation of them on Director Unabara's orders.

## Background

The exact time frame which the past Level 5 and the "previous generation" were active, and the circumstances which led to their obscurity and the creation of Relics, are currently unknown.

The Relic Level 5 was apparently active during a time when Bank requests were made over a phone line charging a user every 10 seconds, with a page taking over a minute to display, mentioning watching images load line by line on a CRT monitor.After their original body was destroyed, likely by Aleister Crowley and Kihara Noukan, their mind managed to survive (though torn and missing memories) and wandered the skies of Academy City, devouring the supernatural as they did so.

In a conversation with Kamijou Touma one year prior to the main story, Shokuhou had mentioned that there was once a Level 5 capable of spatial control.

## Chronology

### Toaru Kagaku no Mental Out

#### Tokiwadai Election Arc

*Main article: Tokiwadai Election Arc*
The Relic(s) played a key role in the events surrounding Shokuhou Misaki's involvement in Tokiwadai's student council presidential election in October, with at least one of them having been created as a byproduct of an incident in September. Prior to her involvement in the election, Shokuhou began investigating the Relic, learning of a supposed close connection to someone at Tokiwadai. Although it had started as a simple investigation, Shokuhou ended up taking out a related institute, with individuals connected to the group involved attacking her in the next day.
