Imari and Shigaraki

Imari (イマリ) and Shigaraki (シガラキ), are a pair of "Yamagami" (山神, lit, Mountain Gods) in which they use stones as their mediums. The two serve as Asakura Mikihisa's guardian ghosts.

About
Imari & Shigaraki are both a pair of Yamagamis; they are a pair of high-level Seirei Class animal spirits of the mountains, and the guardian ghosts of Asakura Mikihisa, which he gained from his travels, training, and hiking in the mountains.

Imari
Imari is a fox spirit that became a mountain goddess in the Chūgoku era when she became older than 1,000. She was originally an evil nature spirit, but the Asakura family defeated her and turned her into a helpful guardian ghost. She appears very intelligent and can change her form at will, but she's also a very skillful and powerful fighter. She is very feminine and noble, and her specialty is becoming a human female. Although Imari is referred to as a female, it is only because she looks like a female ghost but nobody is really sure of it. She acquired her name over 300 years ago by an Asakura who liked the tea ceremony. It appears that her white and smooth fur reminded him of his Imari ware teacups.

Shigaraki
Just like Imari, this raccoon is a nature spirit that became a mountain god when he got older than 1,000. His specialty is changing his form as well, but Imari is the better one. He used to live in an abandoned Buddhist temple until an Asakura Shugenji found him and convinced him to leave that place. From then on he became the Shugenji's guardian ghost. The same man who named Imari, named him after the Shigaraki ware because his fur color had the same deep red color.

Description: By integrating both Imari & Shigaraki into individual small stones, this Over Soul manifests extremely large versions of Imari & Shigaraki, that stand much taller than Mikihisa himself. In this form, they can both make use of their sharp claws and large teeth to attack an opponent, however, Mikihisa rarely makes use of this in battles. Instead, he seems to prefer to use Imari's & Shigaraki's shapeshifting abilities to produce two exact replicas of himself. When this is combined with the Fumon Tonkou ability, it also makes Mikihisa almost untouchable when fighting. However, this ability has a small weakness in the fact that the Over Souls cannot produce a shadow, meaning an opponent could easily make use of this to deduce who is the real Mikihisa. Due to the spirits of large forms, Mikihisa can also make use of them as a form of transport if the situation ever arises.

Trivia

 * It would seem that Imari & Shigaraki are what Ponchi and Conchi would be like if they would give up their large ego. Although neither Imari nor Shigaraki would ever admit it, they hate such a comparison, in every sense of the word. They believe that because they are high-class spirits they can't be compared to the likes of Ponchi and Conchi.
