The ultimate sibling combo risks their lives to face the disaster striking all of the demon realm!
Don't think a relic of the past like 
you can destroy us that easily!
Als ob uns so ’n uraltes Relikt
so leicht zerstören könnte!
¡Una reliquia del pasado no podrá 
derrotarnos con tanta facilidad!
¡Una reliquia del pasado no podrá 
derrotarnos con tanta facilidad!
Ce n’est pas un vestige du passé
comme toi qui nous détruira !
Non credere che una reliquia del passato
 come te possa distruggerci tanto facilmente!
Não ache que uma peça de museu como 
você vai conseguir nos derrotar facilmente!
Какой-то там древности, как ты, 
так легко нас не побороть!
