"7th-Floor Shrine" was Lady Gerd's answer, while Miss Coens recalled what had happened when she first arrived:
"Actually, I first appeared on the 19th floor. Back then, I didn't understand the rules here and rashly lit a light in the corridor, which drew an attack from an evil creature lurking in the darkness. I was leaning against the door to Room 1908 at the time. After the door was stained with that monster's blood, it immediately lit up. The monster was frightened away, and I had a chance to escape. Later, I met Lady Gerd in the stairwell.
"Thinking about it now, there was very likely something similar to a holy relic hanging behind the door of Room 1908."
The room Miss Coens mentioned was on the 19th floor, just like Room 1978, which the mission required them to deal with. If they were lucky, they might run into it directly.
Thus, Shade set his sights on Room 1978 and Room 1908. When he said he did not have much time left and intended to depart for the 19th floor immediately, the Demon Hunter said she could help this time:
"I've mostly recovered, and I know the 19th floor best."
"I'll stay behind this time. I was lightly injured just now and need some more time to recover."

Lady Gerd had also wanted to go to the Nineteenth Floor, but the corridor was narrow, and there was no need for all three of them to go out. Besides, three people traveling together would consume more light.
In the end, Miss Coens accompanied Shade to the Nineteenth
