two monarchs; two rulers
Refers to two sovereigns or heads of state. Rare and mostly found in historical or formal political contexts.

I'd like to hear the opinions of both of you.
Compound of 両 (ryō, 'both') and 君 (kun, 'lord' or 'you'). The exact historical derivation is uncertain, but the word has been used in formal address and historical references to two rulers.
