Yago in Brilliant Pagoda or Haze Castle
Yago Ametsukana (天目津金 ヤゴ Ametsukana Yago) is a god able to forge any weapon and who supplied weaponry for both the Dragonfly Army and Devanagara during the war between both factions. Their ultimate wish is to create a weapon suitable for themself. They are the extra stage boss of the Haze route in Brilliant Pagoda or Haze Castle.
- Creating weapons
They have the ability to create any kind of weapon, but such a weapon is only completed when it finds a suitable owner for use. Presumably, the weapons that surround them in their portrait are those that they have created. In Brilliant Pagoda or Haze Castle they provided weapons for both factions while remaining as a neutral party. Among their known creations are the Tasouken, Kunimitsu Ooya's Bankuruwase and Taira no Fumikado's personal club.
Sugari no Ontachi
The Sugari no Ontachi (須賀利御太刀) is the sword currently used by Yago, which can be seen held by their left hand. Yago uses this sword as a substitute until they are able to make the weapon suitable for them. It is said to be the counterpart of another sword from the Outside World and has lost its original owner and purpose.
In the real world, the Sugari no Ontachi is one of the sacred treasures of the Inner Shrine of the Ise Grand Shrine and is likely named after the bee or wasp-like decorations found on it. Since the rule of Empress Jitō, the shrine has had the tradition of rebuilding every 20 years into an adjacent land with exactly the same specifications, based on the idea that new objects have greater divine power. The sword is a part of the tradition and is often paired with the Tamamaki no Ontachi (玉纏御太刀) as the most luxurious and important swords out of the 1576 sacred treasures across Japan that are renewed every 20 years. Oddly, the two swords feature designs that are characteristic of a period later than the tradition, meaning that they may either be later additions to the shrine or that the swords received a redesign later in history.
Yago is based on several deities and youkai, including the god Ame-no-Mahitotsu-no-Kami (天目一箇神 lit. "one-eyed god of the heavens"), the goddess Kanayago-no-Kami (金屋子神 lit. "child-god of the metalworker") and the youkai Ippon-Datara (一本踏鞴 lit. "one-legged bellows").
Ame-no-Mahitotsu-no-Kami is a god of iron making and blacksmithing, who is known by a number of other names. Most notably, they are identified as the god Amatsumara (天津麻羅), famous for helping forge the mirror (Yata no Kagami) used to lure Amaterasu out of Ama-no-Iwaya, returning sunlight to the world. They are also said to be who the hyottoko mask is based on, which Yago wears on their head.
Kanayago-no-Kami is a goddess of blacksmithing worshipped in the Chūgoku region of Japan, who is said to have taught the people of a village in the Harima Province how to smith various metal objects, in response to their pleas for rain. She is sometimes depicted as a male god instead and is treated as the same god as Ame-no-Mahitotsu-no-Kami as well.
Ippon-Datara is a youkai that has an eye on a thick trunk-like leg, which is occasionally said to be the corrupted form Ame-no-Mahitotsu-no-Kami. The reason they both only have one eye is due to staring at the fire in their forges for a long time; while the reason they have only one leg is from working on the bellows for too long. Both of these were common occupational diseases for blacksmiths, which are reflected in Yago's design, with one of their eye's being covered, and one of their legs altered due to it going bad from an occupational disease.
Their full name is Yago Ametsukana (天目津金 ヤゴ). Their first name, Yago (ヤゴ), is the Japanese word for dragonfly larvae, nymphs or naiads, which is a reference to their support of the Taira clan's efforts to bring forth the true emperor and claim the Dragonfly Castle. According to JynX, "Yago" is written as "水蠆" in Chinese, which is the Chinese for dragonfly larvae, nymphs or naiads.
Yago Ametsukana wears a short, red kimono with brown, black and white straps and a black dress with white stripes. They have a brown eye, the other is covered by a white cloth with light blue dots. They have brown hair and wear a red hyottoko mask. They are carrying a sheathed sword with gold decorations and various knives float around them. They also wear a knee pad and have some metal covering their calf. They wear 2 different shoes: one that is covered in metal and somewhat resembles a knight's footwear and a maroon-coloured shoe. According to JynX, Yago's left foot looks the way it does as it was altered from their original foot after it had "gone bad" due to work-related reasons.
- Brilliant Pagoda or Haze Castle
Yago was entrusted by Fumikado's grandfather to look out for them on their path towards becoming the New Emperor, giving them advice through "revelations".
Yago assisted Iwakado in hunting oni and beasts for building a new body for Taira no Masakado. Yago is a trusted friend of Iwakado, and was entrusted with looking out for Fumikado on their path towards becoming the New Emperor.
While they do not know each other on a personal level, as they are both gods, they know each other's names and faces.
- The surname "Ametsukana" may not be Yago's actual name but the title of their position as a god, as indicated by the Preschool Team's Haze Extra Scenario, where Yago wanted to recruit Sukune as the next "Ametsukana".
- The Paulownia Seals that can be found on Yago's spell backgrounds are often taken by shrines that worship Ame-no-mahitotsu no kami as their shrine crest.
- Yago is described as being "human-like" prior to becoming a god.
- "Made in Yago" is a quote JynX used to reference Yago's creations.
