| Black Imperial Sword Judecca|
The Black Imperial Sword Judecca is a sentient Demon Lord Weapon originally sealed in the Sky Library before contracting with Arata Kasuga. Since then, Judecca has supported her master and eventualy became one of his primary weapons used in battles.
Upon being released from her seal, Judecca initially behaved similarly to an automated artifical intelligence system. However, after forming a contract with Arata, her responses gradually became more diverse and less robotic. As a Demon Lord Weapon, she will faithfully follow her master's desires and strive to fufill his wishes. In particular, she will even indulge with Arata's perversion.
During battles, Judecca can provide guidance and analyze the situation to offer the best course of action.
After taking on her human form, she acts very affectionate and tries to flirt with him. However, she usually ignores all other people except her master.
Judecca's true form is a longsword consisting of a jagged blade with a hook at the tip. Inside the crossguard contains a round gem that stores Judecca's conscience which allows her to communicate with other people. Attached to the pommel of grip is a long skeletal lanyard that can enfold the user's arm for analysis.
After Arata changes his class to that of a Sword Magus, he gained the capability to load spells from the Trinity Seven into Judecca, thus alternating her form as well.
- Fides of Gula - Large medieval blade with a cover guard and long grip.
In her human form she takes an appearance of a young girl in her teens with long white hair and purple eyes. As with most girls in the series she has large breasts. Judecca wears short white one-piece dress. Her other unusual feature is her short pointy ears.
A long time ago, Judecca was sealed by the Spriggans who would guard the Demon Lord Weapon inside the Sky Library for many years. Even after Abyss Trinity destroyed Akio's hometown, Judecca would continue to slumber within the Library.
Sky LibraryEditAkio are unexpectedly forced back into Judecca's room. They initialy are unaware of the Demon Lord Weapon's presence until Lieselotte warns them after sensing the sword's existence. While Lugh and the rest of the group stall the golem, Arata approaches Judecca whose seal suddenly breaks and falls into his hand. Upon contact, Judecca quickly confirms Arata possesses a Demon Lord Element before analyzing his magic. However, after detecting only his Archive Superbia along with Luxuria and Gula, she states that Arata has not yet achieved the Trinity requirement. As a result, Judecca then begins the process to force the Demon Lord within Arata to awaken. Akio attempts to separate the two, however Judecca easily repels her, forcing the ex-Spriggan to use the camera containing Lieselotte to freeze time.
Within the Frozen World, after noticing his arm has partially transformed into the Demon Lord, Lieselotte comments that even if time has frozen, the transformation slowly continues to progress. Arata then forcibly releases Judecca and returns to normal, much to grimoire's concern.Later, after Arata successfully masters Lieselotte's Logos Art and returns with her to the real world, he then summons Judecca who confirms that he has mastered the Trinity before deeming him as her master. Next, he questions if she can defeat the golem which she verifies that she can easily destroy the target. Arata begins concentrating while wielding Judecca, causing his magic to disappear for a moment before quietly eliminating the golem. Arata comments that he is finally understanding how to use magic as a result of using Judecca. Afterwards, Lugh tries to touch Judecca, the sword binds the thief and erotically absorbs her magic.
While Abyss Trinity attempts to awaken Lilith's Last Key, Arata surprised the Demon Lord and uses Judecca to force him back. However, Abyss easily recovers from the attack while brandishing the Red Imperial Sword Caina. Arata, with Judecca, and Abyss, with Caina, then begin clashing with one another, causing destruction to their surroundings. As Abyss orders Caina to invoke his "Fall" magic, Arata nevertheless continues to confront the Crimson Demon Lord while his grimoires analyze, despite receiving minor damange. After Sora and Ilia reveal the nature of the "Fall" Thema, Arata commands Judecca to execute Akio's magic, imbuing herself with Mantra Enchant. Disabling Abyss' magic with his anti-magic, Arata manages to force the Demon Lord back with the strengthened Judecca, destroying nearly half of Sky Library. However, after Abyss forcibly awakens the Demon Lord Element within Lilith in order to regain his original strength, Arata and Judecca find themselves eventually ensnared by his magic. Arata and the grimoires decide to use anti-magic to escape, but Judecca states that his chances are quite small, much to his chagrin. Regardless, along with Akio and Lieselott'e support, Arata manages to liberate Lilith from Abyss' control, as well as gain his fourth Archive and transform into the Trinity Form. In his final strike, Arata uses Judecca to destroy both Abyss Trinity and the Sky Library.
After Finding himself in Akio's ruined hometown again, he questions the whereabouts of Judeccca who reveals herself as a small pendant, confirming the destruction of Sky Library as well as the ability to change into any form of his choosing. When he asks the type of girl she can transform into, the Demon Lord Weapon responds "a very bouncy one", much to Arata's happiness and Lilith's displeasure.
AbilitiesEditAs a Demon Lord Weapon, Judecca can only be wielded by a Demon Lord or Demon Lord Candidate who has achieved the Trinity. If the requirements are not satisfied, she will initate Berserk Mode, which attempts to forcibly awaken the Demon Lord within the user. If someone tries to interfere the process, Judecca then can repel the transgressors, causing them slight damage. The only way to completely halt Berserk Mode is for the possessor to release Judecca which will restore the person to normal. Otherwise, the transformation will continue to progress, even if time itself is frozen.
However, upon successfully forming a contract, Judecca will become quite loyal to her master, providing guidance and support to fufill her owner's desire. Judecca can quickly analyze an opponent or the situation, as well as advice on a course of action .

Additionally, Judecca can transform into any form of her master's choosing, including a a pendant version of herself. She has also hinted at being able to assume a human female form if necessary.
After her master relinquished his Demon Lord Element, Judecca could no longer be utilized, temporarily falling under Abyss Trinity's care for awhile. However, Arata later regained the right to wield her after partially merging with the Weapon, allowing access to her abundant resource of magic. Furthermore, upon becoming a Sword Magus, Arata is capable of loading his spells into Judecca to invoke from, as well as transforming her appearance.

The two first enountered one another when Arata accidentally was forced into the room she was sealed within. Upon approaching the Demon Lord Weapon, Judecca's seal would break and fall itno Arata's possession. However, determining that Arata did not meet the Trinity requirements, she then attempted to force the Demon Lord within him to awaken until Lieselotte intervened. Nevertheless, Arata would later successfully form a contract with Judecca after copying Lieselotte's magic.
Despite forming a contract for relatively short amount of time, Arata has shown to wield Judecca quite effectively, capable of holding his own against the Demon Lord Abyss Trinity. Normally during battles, Arata will usually give instructions to Judecca which she will loyally process. Furthermore, Judecca will also provide information about the enemies and situation, as well as suggest the best possible course of actions to follow.
