Lucia finds herself attracted to Touya after he resolved the coup d'etat at the Regulus Empire. Picking up on that, Yumina proposes that they welcome Lucia in as Touya's fifth fiancee.
Leave wars and guarding the castle to us!
!اترك الحروب وحراسة القلعة على عاتقنا
Ci penso io, che si tratti di guerra 
o di fare la guardia al castello!
Deixe as guerras e a
proteção do castelo conosco.
Обеспечим хоть охрану замка,
хоть войну!
