Rule Fragments, or Hero Relics are ancient magical artifacts such as rings or weapons that are enchanted with unique powers, such as the ability to summon creatures to fight for the user, or the activation of a spell that greatly enhances the user's physical and magical abilities. Throughout the first half of the anime series, Ryner and Ferris travel around the continent searching for such artifacts on the express orders of Sion Astal, King of Roland.

The Ring of the Dark Emperor (黒叡の指輪, Kokuei no Yubiwa)Edit

  • Ring of the Dark Emperor
  • Shadow Beasts

A diamond-shaped ring with a red stone at its centre, this relic was owned by Miran Froaude for the duration of the story. The ring has the power to control shadows, which can take on a variety of physical and magical attributes, such as merging to form a protective barrier for a maximum of eight seconds. Froaude uses the ring primary through summoning "shadow beasts", creatures made from shadow that serve the bearer of the ring. To use the ring, the wearer must utter the incantation, "Let there be darkness!". The stone then glows brightly and its power is activated in whatever way the bearer chooses.

Quoted Passage, History/DescriptionEdit

Ryner speaking clearly with a foreign language: “The legend of the Great Emperor ‘Dark Emperor’…The life of one in darkness. The night of the dark moon. The night curtain. The pitch black wings. The illusion of darkness. The king of shadows. Wherever he was, in the world, in the distance, he was always surrounded by darkness, covered in the endless universe— That was the legend of the shadow king who covered the world. There were also rumors that he was actually human…as he carried out cruel violence in the world, he was viewed as a demon lord…but this king gave a ring with mysterious ability to his most capable subordinate, which was…The ability to manipulate shadows. After that, the subordinate used that power to kill off important people in opposing countries one by one, and the Dark Emperor’s land expanded. However…when that subordinate was about to kill an important person from a certain country, a knight who was protecting that person sliced off the finger with the ring and stole it, and the Dark Emperor was finally killed by the power of the shadows…the story goes like that, I guess? However, it’s still a mystery how the Dark Emperor had such a mysterious ring and where the ring came from. The manuscript never left these details…but the name of the knight who took that ring became famous as a legendary hero who saved the world, and he’s definitely called…He’s definitely called, yes, Halford Miran.

The Comb of Elemio (エレミーオの櫛, Eremīo no Kushi)Edit

  • Elmio Comb
  • Sui Orla using the Elmio Comb to defend himself

This artifact is shaped like a comb and can be used to fire a powerful shockwave against the enemy. In the anime, however, instead of firing a shockwave, its function is to nullify all magic cast at it, which theoretically makes it an ideal weapon to counteract a berserk Alpha Stigma bearer, though Ryner demonstrated that its power is not absolute by destroying it magically. It is owned by Sui Orla for most of the series, but was lost after he was killed, and it is not known what happened to it afterwards.

The Blade of Dolueli (ドルエリの剣鱗, Dorueri no Kenrin)Edit

  • Sui Orla activating the power of the Blade of Dolueli
  • The Blade of Dolueli
  • The dragon created by the Blade of Doleuli

This relic was left behind by Ryner and Ferris after they discovered it, having not been able to identify the correct way to use it. It was retrieved soon afterwards by the Orla siblings, who were also collecting hero relics, and who knew how to use it, unlike Ryner and Ferris. It was used by Sui as a weapon against Ryner and Ferris in their first fight. The Blade of Dolueli is in the form of a dagger with a blue blade, and upon invocation by stabbing the sword into something, which takes the form of a dragon, who's strength varies depending on the strength of the user's will. In Sui's case, the dragon encompassing his whole arm where he stabbed himself. The only anomaly was when Ryner accidentally created/summoned a dragon the first time he misused it. Later, Sui revealed this phenomenon had occurred because the ground has no will, unlike humans, and as such it created a dragon instead of transforming into one. The Blade of Dolueli was taken by Miran Froaude after he killed Sui Orla. Just what happened to the dragon after it fell off is unknown.

Quoted Passage-Description/HistoryEdit

*quoted from Densetsu no Yusha no Densetsu: Volume 3

“From a distant land. It spreads life, birth and death. Flaming fires Night made day by the flames Distant, twilight, jealousy, nightmare. It will bury this world and hell in shadows at midnight…” Ryner: “Anyway, about what I was talking about, the beginning part was introducing the Demon King of the world then.” Ferris: “Demon King?” Ryner: “Yes, this case is different from the legend of the Dark Emperor who was a tyrannical king of his empire. This was a real Demon King. See you can tell from the line ‘From a distant land’. It’s a story about him appearing suddenly and plunging the world into an era of fear. Sounds amazing, doesn’t it?” Ryner: “But let’s leave that aside… The main point was that. Anyway, a Hero’s sword might have been left in this fortress. Simply said, a powerful Demon King appeared then and a knight called Claus Gabardi… defeated him and was named the knight in the legend of the Heroes. After that knight died, the sword that he had used to defeat the Demon King was left in the ground somewhere near here…But there’s been some discussion that this sword cannot be retrieved by anyone…”(Based on BTT)

The Scythe of Ailuchrono (アイルクローノの鎌, Airukurōno no Kama)Edit

  • Kuu Orla wielding the Scythe of Ailuchrono
  • The Scythe of Ailuchrono

This relic, possessed and used by Kuu Orla as her sole weapon, is in the shape of a large scythe, and rapidly increases the wielder's strength and speed, allowing Kuu to easily match up to Ferris' speed. The blade also has the ability to freeze anyone and anything that comes into contact with it, and Kuu manages to use this ability to stop Sui from bleeding to death. As a side effect, the artifact "freezes" the wielder's heart as well and Kuu will lose all her emotional capacity when she's wielding it.

Quoted Passage-DescriptionEdit

“It was completely green, the blade was made of some unknown metal. And it was not clear what material it was made of, the hilt was carved with twisted strange flowery patterns. The scythe that can increase the strength of the body also has the power to create a wall of ice and freeze the blood of its corpses. But, that power is more dangerous than imagined. Just by cutting a few times, Ferris’ sword has been frozen and it has been getting heavier. The surrounding temperature is also lowering, Ferris’s body activities aren’t so sharp…” (DYD Vol. 3)(From BTT)

The Ring of Thunder Beasts (來獣の指輪 ?)Edit

  • The Ring of Thunder Beasts
  • Lightning Beasts summoned by the Ring

This artifact is owned by Ril Orla for the entire series, and it allows him to summon magical "beasts of light" to fight alongside him. The Ring is said to be on the same level of power as Froaude's “Ring of the Dark Emperor”, and works in much the same way. The Ring itself is square and golden, and its power appears to source from the Ring itself rather than from a stone or jewel set in it. The incantation used to summon the "lightning beasts" is, among other variations, "Lightning Beasts, arise!". Because the ring has the same amount of power as the Ring of the Dark Emperor, the strength and capabilities of the lightning beasts are the same as those of the Shadow Beasts.

Rock Devourer (石喰い, スパンクエル?,)Edit

  • The Rock Devourer
  • Ril Orla evoking the power of the Rock Devourer

This artifact, owned by Ril Orla, is a large, green, spherical stone which is used by the holder to extract crystals from the eyes of cursed eye bearers. The extraction of crystals is a rather gruesome process, as the crystals are forcefully sucked out through the eyes, resulting in an instant, bloody death. After extraction, the crystals can be kept by the user of the stone as weapons to be used at a later time.


  • Glouvil
  • Rifal Edia summoning the Spirit of the Sword

Glouvil is a large, two handed sword, owned by Refal, King of Gastark. The power of this Rule Fragment grants enormous destructive powers to the one who wields it, but in return that one has to sacrifice something important. In order to use the sword, the bearer must summon the spirit within the sword, presumably with their mind, and tell the spirit what they are willing to give as compensation. The compensation, however, will not be taken until after the power of the sword is unleashed. Refal had already sacrificed his sense of smell, sense to feel (Manga Only) and his right leg when he sacrificed his left eye for the power of the sword just after meeting Kiefer.

Latsel ThreadEdit

Latsel's Thread

Luke Stokkart using the Latsel Thread.

The latsel thread is a rule fragment used by Luke Stokkart after he picked it up when Ryner accidentally left it behind. The Latsel Thread stretches out infinitely and although it may not be very useful in fights, it allows the user to set up traps against their opponent making it very deadly if used correctly.
