Ama no Murakumo no Tsurugi (Sword of the Gathering Clouds of Heaven), also known as Kusanagi no Tsurugi (Grass-Cutting Sword), is a legendary black Japanese sword, and part of the Imperial Regalia of Japan. It was formerly the property of the former Heretic God Susanoo and considered a demigod. Ama no Murakumo no Tsurugi is a demi-god of Steel and has shown the Authority of Wind control, and the ability to enhance the wielder to a point where they can surpass the abilities of a Great Knight. It can also possess its wielder when they are in the Netherworld. It's suggested that both of these require the power of Divine Possession to accomplish though. Since its introduction, Ama no Murakumo has revealed the ability to adsorb Authorities, whether those of its wielder Godou, or those of an attacker, to provide power, and transform them into new abilities. After absorbing the power of wind from the Authority of Luo Hao, it granted Godou the power of shockwaves from his punches, when adsorbing lightning created from Godou's Authority, it developed immense magnetic powers, and other abilities.

Ian (イアン) is a member of the Stationary Guard in Trost District. Ian first appears in Ch. 5 after Trost District is breached by the Colossal Titan. He compliments Mikasa for killing a Titan that was attacking a group of evacuating civilians. In Ch. 12, a plan is formed for Eren to use his Titan powers to seal the breach with a boulder. Ian is placed in charge of the elite squad assigned to protect Eren on his mission. When Eren loses control of his Titan form in Ch. 13, Mitabi and Rico advise Ian to abort the mission and retreat. However, Ian orders his soldiers to continue to defend Eren down to the last man, as Eren is their only hope against the Titans. In Ch. 14, Eren regains his senses due to Armin's intervention, and Ian orders his soldiers to protect him until he reaches the breach even at the cost of their own lives. Ian uses himself as bait to lure Titans away from Eren, sacrificing his life in order to ensure the success of the mission. First Appearance Anime: Ep. 5 (Source: Shingeki no Kyojin Wikia)
