Shiraha Social Support Club

Shiraha Social Support Club (白羽社交応援会) is an unofficial salon that is found in the School Garden. Officially, it is an independent archery training group, but the members’ actual goal is to create connections with large corporations mainly from the financial world.

Principles
Despite being middle-schoolers, with about 20 members, the group's goal is to create connections with large corporations. Their leaders apparently love kimonos and wall scrolls.

The club rented out an entire small building for themselves. From the outside, it looked like a bank and was protected by a door that is sturdier than a bank's, requiring an authorization card for members to enter. Inside, the establishment looks like a Japanese-style room with tatami mats and paper sliding doors. According to Shokuhou Misaki, its looks a part of the scenery preservation. It is the same as a hologram. Tiny indentations and protrusions are made on the glass like on a CD to alter the condition ability of the light to make a Japanese-style room look like a Western-style lobby.

Agitate Halation Arc
The establishment is the final part of Kamijou Touma's wild goose chase for the Altar of the Wisdom King set up by Tsuchimikado Motoharu.

With the help of the 5th Level 5, Shokuhou Misaki, controlling a local from the School Garden, they arrive and able to infiltrate the building, which would be the most likely place the Altar would be kept. However, as soon as Touma discovers that Motoharu has played a ruse on him and he discovers news of his friend, Tsuchimikado Maika, dying in a fire in her dormitory, Touma quickly abandons the search.
