The Demon Sword Lostvayne「魔剣 ロストヴェイン, Maken Rosutovein」is a Sacred Treasure belonging to the Dragon's Sin of Wrath, Meliodas.


Meliodas wielding Lostvayne 10 years ago.

Lostvayne is a curved shortsword with the Dragon tattoo emblem into its hilt and five holes along the middle of the sharp blade, and 5 half-moon holes along the other side of the blade. The blade is split into two different colors, the sharp part is silver and the opposite is a dark green moss. When Meliodas uses Assault Mode, the blade of Lostvayne apparently turns completely red.


Lostvayne was created by the Giant Clan's master craftsman, Dubs.[1]

Lostvayne was entrusted to Meliodas by King Bartra, and was in Meliodas' possession until 10 years ago when he sold it in order to raise money to open the Boar Hat. Merlin later bought it from a pawn shop in Camelot and kept hold of it until she returned it to Meliodas during Albion's attack on Camelot.


Albion arc

While saving Arthur from Albion's attack, Meliodas' sword, which was a gift from Liz, gets broken, leaving him without a weapon. This prompts Merlin to return Lostvayne to him in order to combat the giant monster.


By saying the command "Sacred Treasure Activate"神器発動じんぎはつどう, 'Jingi Hatsudō'」, Meliodas can use Lostvayne's abilities.

  • Jitsuzō Bunshin実像分身じつぞうぶんしんliterally meaning "Physical Clone"」: Lostvayne's special ability that allows Meliodas to create up to four or six clones of himself.[2] The clones only retain a fraction of the original's power, with one clone having half the power level of the original. The halved power level is divided among each additional clone.[3] Each Physical Clone is still able to use Full Counter to its full potential as the attack focuses on the enemy's attack power rather than the one using Full Counter. This allows Meliodas to use Full Counter multiple times on the same attack. Depending on the enemy and Meliodas's power level, it is additionally possible for him to use his clones to fight the enemy as well as dealing and taking damage without Meliodas himself getting involved in the fray.[4]


  • Lostvayne is the fourth Sacred Treasure to be revealed in the series.
  • Lostvayne was worth a thousand gold pieces when Meliodas sold it in a market in Camelot.[5]
  • In the movie, Meliodas created six clones of himself.
