Shinden and Raiden

Shinden (震電) and Raiden (雷電) are a pair of komainu spirits and the Guardian Ghosts of Asakura Luca.

About
Shinden and Raiden are the spirits of a pair of dogs that the branch family once owned.

O.S. Amaterasu
O.S. "Amaterasu" (O.S.  Amaterasu) Description: Using her star wand, Luca turns Shinden and Raiden into motorcycles which pull a large shrine like a chariot. According to Yohane, the shrine itself is actually created by a third, unknown spirit. Despite its size and apparent speed, this Over Soul was easily stopped by the defensive form of Asakura Hana's Oni Kabuto.

In its true form, called Mobile Shrine: Ark Amaterasu (機動神社), Luca is able to change Shinden and Raiden's motorcycle-like forms into legs, turning the Over Soul into a walker. It is able to fire a beam that can dissolve Furyoku, and by unknown means, it can also petrify spirits, rendering them useless in the process.

Attacks


 * Kachiyumi: In its mobile form, it performs a rapid stomping attack.


 * Wondrous Light Beam (無無明怪光線): The eye of the shrine fires a beam that is capable of dissolving Furyoku upon contact. However, Over Souls with mirrored surfaces can deflect the light without being nullified.

O.S. Big Zalim
O.S. "Byg Salem" (O.S.  Biguzaremu) Description: Using an unknown technique called Gion Gattai (祇園合体), Luca and Yohane are able to combine their Over Souls into one, giving it the strength of Yohane's Tsukuyomi and the speed of Luca's Amaterasu.
