This possession made me laugh the longest and the hardest. Do I even need to explain why this is hilarious?
 
Their Double Action lyrics:
 
Kintaros: Flowing, its flowing, this aimless journeythis once-in-a-lifetime encounter  
Rarity: Gleaming, its gleaming, like pure diamond  
Rarity & Kintaros: this generosity is growing slow  
Rarity & Kintaros: Mine, this strength of mine, youve wept over this generous strength of ours  
Rarity & Kintaros: When the voices of 2 overlap each other, we will be stronger than anyone else  
Lets get going now, Double-Action! When Beauty & Power become a single fashion  
Kintaros: With an ax held in my hand, onto a train of Time I boarded  
Rarity: Wiping my tears in a storm of threads I weave past and future  
Rarity & Kintaros: Flaming, this flaming, weeping over this flaming compassion of ours  
Rarity & Kintaros: When the voices of 2 overlap each other, the strength is not to be reckoned with  
Lets start running now, Double-Action! When Heart & Strength become a single Miracle  
Kintaros: Even if it was an Imagin, I will face it spiritedly  
Rarity: Now is the time for the flame of your life to burn strong!  
Kintaros: When this power is released, this Time-Space will be dyed gold  
Leave me to me to Do the Action! Lets get movingDynamic!!  
Rarity & Kintaros: When the voices of 2 overlap each other, we will be stronger than anyone else  
Lets get going now, Double-Action! When Beauty & Power become a single fashion
