Auxesia's jacket features Hikari (Summer) and Tairitsu (Summer), and must be unlocked first to access their limited event map, which debuted in summer 2018.
This is the only event song where the required song was already in the game before the event started.
Hikari (Summer) and Tairitsu (Summer) are also the first partners to appear in a jacket before being added to the game as Partners.
This song is playable in CHUNITHM and Cytus II as part of their collaborations with Arcaea.
In Greek mythology, Auxesia (also known as Auxo) was one the Horae, goddesses who personified the seasons. Auxesia herself was the personification of summer, and the goddess of growth, vegetation, and fertility.
