Yamaiko Shrine

Yamaiko Shrine (やまいこ) is an area located somewhere in the Great Tomb of Nazarick.

Background
The shrine was created by the Supreme Beings as a prank on Yamaiko. Due to the female guild member impressive luck streak with gacha, the members of Ainz Ooal Gown called her the “Gacha God” and built the shrine not just for fun but also to see if they could attach some of Yamaiko’s luck on themselves. The area was closed off by Momonga due to the immaturity of concept. But since the transfer to the the New World, it was later re-opened, after Momonga, now going by Ainz Ooal Gown, had removed some of the party refuse that was left behind at the shrine's inception from the grounds, to allow Aura Bella Fiora and Mare Bello Fiore to conduct a "Shichigosan".

Layout
The area is unique in there is a stylized artificial sky containing clouds. It is designed with standard layout of a Japanese Shinto shrine. The entrance starts at a torii which leads to the shrines facilities down a path stone path, flanked by tōrō on either side. The path leads to the hall of worship which is guarded by two komainu statues.

It contains several cassottes which visitors must use by via instructions on a sign> As it states a visitor must use their right hand and pour water on the left hand to clean it and then repeat process by holding with the left hand. Then hold the cassotte with their right hand and pour water into the left hand to use to rinse their mouths before rinsing the hand with the water from the cassotte. And finally tilt the cassotte vertically and pour water on the handle to clean it. According to Ainz the whole process to mean to symbolize abandoning all desire as it was believed that doing so would improve gacha results.

Sandō
The road that approaches the haiden. The path actually contains a gimmick, should a person walk on stone pavement, a water attack blast will shoot from the hall and knock the pedestrian out of the shrine's boundaries. Hence it is recommended for pedestrians to walk beside the sandō. Peroroncino failed this precaution and ended up be knocked out of the area.

Haiden
The hall of worship of the shrine. It houses a coin box where visitors can offer coins and prayers to the shrine's deity. In addition there is a suzu that hangs before the hall to call out the god of the shrine. Once the bell is rung it activates a visual lottery displayed as a holograph to show the visitors omikuji. There is also an anti-theft feature, as if a person tries to steal the contents in the coin box, the haiden will open to reveal a Komainu golem that will attack the offender.

Trivia

 * Tabula Smaragdina contributed to the shrine by adding the omikuji lottery function at the haiden. Though Ulbert Alain Odle complained that he made the lottery setting of the "Great Villain" slot to be deemed the rarest and the worst fortune, in which Ulbert believed that it should be the best fortune instead.
 * It is unknown which floor the shrine actually is situated on as the manga did not reveal it's exact position though its presumably located on the 9th Floor given Guardians like Aura and Mare were unaware of its existence until Ainz showed it to them.
 * The Komainu golem was installed by Luci★Fer.
 * The shrine's sky background is oddly similar to the Chaos Zone containing the Takemikazuchi Shrine or Bishamonten Shrine from Mass for the Dead.
