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...
He's definitely the Vice Captain

¡Viva el vicecapitán
de los Leones Carmesíes!
¡Viva el vicecapitán
de los Leones Carmesíes!

du Lion flamboyant !
Non per niente è il vicecomandante del Leone Cremisi!
É digno do Vice-Capitão
dos Reis Leões Carmesins!
Вот это я понимаю,
вице-капитан «Багряных львов»!
