An early COMP carried by the protagonist in Shin Megami Tensei

A COMP, also known as an Arm Terminal, is a device commonly featured in the Megami Tensei franchise. It refers to the portable computer which many characters have used in order to communicate with, transport, and summon demonic entities using the Demon Summoning Program. It is one of the most common elements to appear in Megami Tensei games.



Digital Devil Story: Megami Tensei novelsEdit

Akemi Nakajima carries a small hand-held computer with him at all times, which he uses to summon Cerberus at any time. Charles Feed also carries a similar device.

Megami Tensei IIEdit

The COMP serves the same purpose as it does in other games. Pazuzu also uses it as a means of communicating with the hero. The amount of demons the COMP can hold is increased once the hero's missing arm is replaced with a cybernetic one.

Shin Megami TenseiEdit

The protagonist carries a COMP which he uses to communicate with demons. It houses the Demon Summoning Program designed by Stephen. Stephen later upgrades the protagonist's computer so that it can store more demons.

Shin Megami Tensei IMAGINEEdit

Each player character in Shin Megami Tensei IMAGINE carries a COMP. In the start of the game, the player can choose between two models. Snakeman upgrades the player's COMP once they become a Devil Buster.

COMPs in IMAGINE can also come in a variety of vanity forms such as bracelets, glasses, rings, umbrellas, knuckle guards, gloves, digital books, and PDAs. These have unique summoning animations and are usually acquired through the cashshop or in-game events.

Shin Megami Tensei IVEdit

"A bracer worn by Mikado's Samurai. It functions a lot like smartphones, complete with Demon Summoning Program and map navigation. And like the phones Hunters use, Gauntlets also have onboard AI support.

Gauntlets are installed with the "Burroughs" operating system. She provides various support features essential to Samurai."
Shin Megami Tensei IV Apocalypse Notes, entry - "Gauntlet"

The COMP returns in Shin Megami Tensei IV in the form of a gauntlet. Those who are to be tested whether they will become Samurai or not must pass the Gauntlet Rite. 

All Gauntlets come with an assistant interface avatar called Burroughs, who is often referred to as a fairy. Burroughs guides Gauntlet users through demon data, application usage, navigation, among other functions within the limits of the Gauntlet's internal database. Mido aids with fusion and compendium data.

Gauntlet users can also learn active skills from well-raised contract demons via the "Demon Whisper" ritual. The Hunters of Tokyo and the Ashura-kai use smartphones to summon demons. The Demonicas seen in the game are armor worn by the Counter-Demon Force and it is noted that the vambrace on the Demonicas resemble the Gauntlets used by the Samurai.

Shin Megami Tensei: Devil SummonerEdit

The Devil Summoner Kyouji Kuzunoha comes equipped with heavily modified gun that has been integrated with a compact COMP system. The hybrid device is known as a "GUMP", which is a shortened term for Gun-COMP. Aside from its obvious purpose, it still functions like a regular gun.

Sid Davis uses a COMP modeled after a bible.

Devil Summoner: Soul HackersEdit

The GUMP reprises its role as the main demon utility device and primary sidearm, but has undergone a few cosmetic and functional improvements over time. Its use is now widespread among the majority of the active Devil Summoners.

Aside from the GUMP, there are also COMPs modeled after guitars, parasols, saxophones, and brass knuckles.

Shin Megami Tensei Trading Card: Card SummonerEdit

Card Summoner has the Arm Comp, which keeps track of the player's money and Victory Battle trading cards. The GUMP also appears in the game.

Devil SurvivorEdit

COMPs (short for Communication Players) bear a striking resemblance to the Nintendo DS (Nintendo 3DS in the 3DS remake). They were initially advertised as gaming consoles which allowed for web browsing, email and international online gaming. Its commercial tag line was "Play with people around the world!"

Naoya gave the protagonist and his friends specially designed COMPs to survive the Tokyo Lockdown. Aside from the Demon Summoning Program, a secondary application called the "Harmonizer" tunes to the wavelengths of humans, making attacks effective against demons while lessening the damage taken from them. The Harmonizer affects all humans and demons that are within range of the COMP.

COMP users came to be known as "Demon Tamers". The first time the Demon Summoning Program is initiated, a demon will emerge whose strength is proportionate to that of the user. A contract will not be forged until the tamer defeats said demon. Latter demons are obtained by participating in an online auction using Macca for purchase and contract enactment.

The COMP's battery life is limited; since electricity was cut off in the lockdown area, the only way to keep a COMP functional is by charging it with a hand-crank dynamo. This was the main concern that the party had in the beginning. They received one such device from Keisuke.

If the COMP runs out of battery power or breaks, a Demon Tamer loses their demon contracts and in turn will also make them vulnerable to demon attacks due to the disengagement of the mind link to the Harmonizer. The Demon Summoning Program can also go rampant, creating portals for demons to freely emerge from.

Devil Survivor 2Edit

The COMPs in Devil Survivor 2 are actually cell phones that have downloaded a demon summoning app, created by the Anguished One. Unlike the COMPs in the first Devil Survivor, these COMPs do not have much inhibitions at all aside from the fact that when destroyed, the Demon Tamers relinquish control of his or her demons.

Persona 2: Innocent Sin (PSP)Edit

Though Demon Summoning programs do not play a role in the main story, COMP-like devices are prominent in the Climax Theater quest, Persona Thief. The main antagonist, Tamaizu Nirasawa, claimed to have created and placed a Demon Summoning program into a handheld computer, reminiscent of the original COMP created by Akemi Nakajima. One of the other major characters in this quest, Haruo Weyland, summons demons from an effects panel on his guitar called the "Infectious Groove", a reference to Carol J and his guitar GUMP.

The Devil Children seriesEdit

The Devil Children use devices called Devil Risers, which are gun-shaped computers used for carrying and summoning demons. In addition, Devil Children carry a personal computer called a Vinecom, which aids in organizing information and sorting demons. Later in the story, protagonists often obtain the King Riser, which works as a second Devil Riser compatible with stronger demons.

  • In Persona 3, the player needs a "portable game system" to fulfill one of Elizabeth's Requests. While the item itself is referred to as the "Handheld Game", Junpei states that the system is called the COMPstation Portable, clearly referencing this device (as well as the real-life PlayStation Portable). He says he can give the player his old model since he got the redesigned one.
  • In the murder mystery visual novel game Danganronpa 2: Goodbye Despair the player can collect a set of collectable items called Monokuma Dolls in each island (five dolls in each), in one of the islands the player can find a set of five Monokuma Dolls wearing the COMP device.
