Birukaze (a Touhou LW original) refers to the irregular and wild wind caused by highrises obstructing the regular air currents. This is the temperament of Sanae, as a Shinto priest to a god of wind. This Sanae's temperament was artificially augmented by science since her original temperament lost its magic. This temperament is specialized to solely resist Moon Essence.

Sanae Kochiya's sealed ability. It was most likely sealed away due to the incident, and it hasn't fully recovered since. The reason for this is still unclear and requires further investigation. Sanae Kochiya's Specialized Military Outfit: The design and manufacture of this outfit were largely based on the information provided by the Technology Youkai Network. The two main contributors to this network are Kanako Yasaka's Knowledge Institute, headed by a god of war who is also an engineering revolutionary, and Suwako Moriya's Technological Works, led by a god with a deep connection to iron and steel. All of the specialized military outfits are equipped with barrier chaff. Assault Armor Series: ο-Cannon: This weapon is a remake of Kanako's divine pillars. Sanae usually carries it on her back, but it swings down to her hip with the barrel facing forward whenever she wants to use it. (Sanae specifically requested for it to be designed this way.) It looks similar to Marisa's mini hakkero multi-purpose launcher because they stole a copy of its design and manufactured this weapon on it. They did this so the weapon could shoot a range of different bullets types and to ensure that it would have a lot of firepower. Assault Armor Series: γ-Nail: This weapon is a remake of one of Suwako's divine aspects, the Toad God. It has a built-in super vibration nail that directly utilizes the ritual framework. The weapon is also equipped with the ability to shoot lasers in the shape of iron rings. Assault Armor Series: ν-Railgun: This weapon is based on Sanae's purification rod, but it has been altered to include a few additional features. It is directly linked to the ritual framework and has the power to cause miracles to occur artificially. The gun's fire mechanism uses electromagnetism, so a variety of different bullet types can be shot. Backpack: This backpack is connected to each of her armaments and distributes energy to them. It also houses aiming assistance sensors and various subunits, including the Frog Unit and the Snake Unit. Ritual Framework: This structure contains a network of subatomic substitute prayers and is installed into each and every one of Sanae's armaments. It is exceptionally durable. Each substitute prayer has power equal to the faith of one follower, and the network can simultaneously activate all of them at once. This allows Sanae to artificially activate miracles that would normally require a prolonged ritual.
