Zodiac Art Gallery

The 12 Constellations Art Gallery houses the works of the famous French sculptor Paul Holic, collected from all over the world. Opening hours are 10:00 to 17:00. The director of the gallery was Tsukasa Oyashiki, former star of Dansweets.

History
The gallery itself is the reopened and renovated mansion of Issei Tenkai. Tenkai lost his mansion after he was convicted as an accomplice to murder in the IS-7 Incident. Ever since then, Oyashiki had been gathering money, with the help of the defense attorney Tateyuki Shigaraki. She eventually bought the mansion and rebuilt it into an art gallery presenting Holic's works, as Oyashiki was his fan. When collecting his works, she realized that the IS-7 victim's body, which went missing 18 years ago, was still frozen in one of the statues. She announced a grand opening, hoping that it would attract the real criminal of IS-7. The gallery was opened on April 2, 2019. Shortly after, director Oyashiki was arrested in Autumn Palace for attempted posioning of Yutaka Kazami. Fortunately, Miles Edgeworth and Tateyuki Shigaraki were there to solve both the case and the IS-7 Incident.

Layout
There are four main rooms in the gallery, called "palaces", each named after a specific season. All of them are decorated and have a temperature corresponding to their seasons and house specific sculptures of Holic, all of them named after constellations:
 * The Spring Palace - (12 °C) Leo, Cancer, Virgo
 * The Summer Palace - (26 °C) Libra, Scorpius, Sagittarus
 * The Autumn Palace - (18 °C) Capricorn, Aquarius, Pisces, Aries
 * The Winter Palace - (3 °C) Taurus, Gemini

Additionally, all rooms are equipped with sprinklers, which are manually controlled from the security room on the first floor. On the second floor, there is a medical room, equipped fully enough to create a poison antidote on the spot.
