Kaisen in Brilliant Pagoda or Haze Castle
|Species||Sacred Animal (Toad)|
|Abilities||Gathering financial fortune|
Kaisen is responsible and straightforward and thus, is often irritated at Kujiru's impulsiveness. They hold their master Garaiya in high regard and often picks fights with Kujiru, since both want to be favored by their master. Both shikigami have a fierce rivalry and are often seen insulting each other. Kaisen also has a complex that they are more underdeveloped compared to Kujiru.
- Gathering financial fortune
- Changing forms
As a shikigami, they also have the ability to change into a human form. Their true form is seen in Garaiya's character art, where they are seen to be a toad riding on their master's head.
Kaisen is largely based on the Japanese interpretation of the Chinese mythological creature Jin Chan (金蟾), lit. golden toad, which is known in Japan as Seia-jin or Chinwa-jin (青蛙神), lit. green frog god. It has three legs, two front legs and one hind leg, which is positioned like a tadpole's tail at the back of the toad. Jin Chan was said to be able to spew treasure from its mouth and that if it shows up in front of your house, the family will receive financial fortune and happiness, which is referenced in Kaisen's ability.
Kaisen also has their origins with the Chinese Daoist and legendary immortal Liu Haichan, whose first name translates to sea toad, and is considered an embodiment of the Chinese God of Wealth, particularly in charge of financial fortune. In a particular Chinese legend, one of Liu's relative was a corrupt official who had been reincarnated into a malevolent three-legged toad and cast into a "sea of filth" after his death. Liu then tamed the toad which became Jin Chan, and it was henceforth the immortal's companion. Kaisen's relationship with Garaiya may be a reference to this myth.
A possibly-related legend also depicts a three-legged toad living on the moon, whether this toad is Jin Chan is unclear, as some other legends also have the toad as a transformation of Chang'e after she flew to the moon. This might be what Kaisen's title, "Three-legged Moon Seeker", is a reference to.
Their full name is Kaisen Azuma (東 海仙). "Azuma" is a common family name, used in Western Japan and the Ryukyu Islands, meaning East. While the characters for "Kaisen" mean ocean and a sage or an enlightened person respectively.
Kaisen has short brown hair and brown eyes. They dress in grey and brown clothing with tadpole ornaments and a hat composed of numerous tadpoles. Truth be told, Kaisen has a prosthetic foot, which they try to conceal with a pair of long grey boots. In their animal form, Kaisen is a white toad as big as Garaiya's head and has five tails.
- Brilliant Pagoda or Haze Castle
While Taira no Chouki was training under the tutelage of Garaiya, the Dragonfly Castle appeared before Chouki, which Garaiya took as an omen acknowledging them as the New Emperor. The idealistic Garaiya wanted for the emperor to be a “hero figure” to Mugenri, but unknown to them, Chouki actually had no interest in ruling. Knowing that Fumikado will eventually come to the castle and fight for the emperor’s title, Chouki waited for them inside the castle, with the intention to kill and have revenge on Fumikado.
Meanwhile, Garaiya sends Kujiru and Kaisen to recruit followers to their cause and monitor the Senri Shrine and its new employees. However, the reckless and overconfident Kujiru went on their own, separating them. After Kujiru and Kaisen are defeated by the heroes, they go back to Garaiya and tell them what happened. Garaiya and their shikigami (back in animal form) fight against the heroes in order to prevent them from reaching Chouki and the Dragonfly Castle, but is defeated easily, since Garaiya was weakened due to using most of their power to enhance Kujiru and Kaisen.
- Kujiru Kesa
Kujiru is Kaisen's subordinate. However, they seem to have little respect for them and disobeys them, because Garaiya favors Kujiru rather than Kaisen. Because of this, Kaisen is jealous of them and both are always seen bickering or insulting each other, much to Garaiya's chagrin.
- Garaiya Ogata
Kaisen is one of Garaiya's shikigami. The toad holds them in high respect and often picks fights with Kujiru in order to get their master's approval.
- Taira no Chouki
Despite the Dragonfly Castle's revelation to Chouki, Kaisen does not trust them and thinks that Garaiya was wrong for siding with them.
- Kaisen, along with Kujiru, lacks a common phrase in their theme that most people associated with the Dragonfly Army have, this is because they were bound by their shikigami contacts to Garaiya, and did not join on their own accord.
