As Asta and the others were chasing the creature that lived in the cave beneath the Yultim Volcano Trail, they happened upon a dungeon. They were then ordered to explore the dungeon by the royal capital, so they split into groups and went in. They head in with Leopold and Vice Captain Randall, but those two end up running into the creature from earlier. They work together but cannot defeat the monster, which makes Leopold feel useless. At that moment, Leopold remembers the strange feeling he felt when he was fighting the elves, and...
When you fought against me after 
my body was taken over by an elf.
.عندما قاتلتني بعد أن أخذ الإلف جسدي
Als du gegen mich gekämpft hast,
Cuando te enfrentaste
a mí poseído por un elfo.
Cuando te enfrentaste a mí
poseído por un elfo.
Quand tu m’as affronté
alors que j’étais possédé par un elfe…
Quando ero posseduto da uno
 di quegli elfi e tu mi hai affrontato!
Quando você lutou contra mim quando
meu corpo foi dominado por um elfo.
Когда сражался с эльфом,
который овладел моим телом!
