That potion is just part of the story. You don't need to use it and the "fairy" is just High Pixie. You will "find" her after you clear area 13-4.

To enter area S13 you need to get all the "War Trophies" from 13-2: two Rods, Messenger, Merchant, Military Band and Exorcist. Use cards like Cassandra or Dog Sled Girl on the battles so you can get a "war trophy" if their skill procs.

There's really no advantage of clearing area S13. It costs 10 vitality per step (600~ vitality to clear both areas) and you only get one ATK and one DEF arcana for clearing S13-2.
