Kirika and Shirabe sing "Orbital Beat" at the school singing competition.  Not wanting to fight them at the  school, the wielders agree to fight a duel at another place. But when they arrive, instead of the girls they find Dr. Ver.
Stronger, stronger, simply staring 
at the Sirius within my heart.
أقوى فأقوى، أحدِّقُ ببساطة بالشِّعرَى في قلبي
Stärker, stärker, ich betrachte
den Sirius in meinem Herzen.
Solo puedo buscar las estrellas 
de Sirio en mi corazón
Solo puedo buscar las estrellas 
de Sirio en mi corazón
Plus fort, plus fort
Più forte, più forte, sempre guardando
Sirio dentro il mio cuore.
Forte, mais forte, apenas olhando
 para Sirius com o meu coração
