Following the group of local Magical Girls as they left the New District of Bai'an City, Emerald Sparrow flew with them to a street in the Old Town district.
The street they arrived at was somewhat old, and most of the buildings by the road had seen better days; however, this did not affect the normal life of the people who had been living there for a long time.
Because it was the Old Town district, the street was lined with shops of various storefronts. Bai'an City is known for its music, so a considerable number of the shops incorporated this element; there were music bars, piano stores, and concert halls.
And the place that the Magical Girls took Emerald Sparrow to was an old piano store that looked like it had quite some history.
"This is our usual base of operations,"
Bai Ji introduced it as follows, "It's a piano store founded by Lamp's parents. Later, her parents handed over the piano store to her, so now Lamp is the manager here."
