*you return home after yet another day in the woods* Afternoon, Eirika! *you announce yourself* I've brought some game I hunted! *you set the meat in the kitchen*

*Eirika bounds across the house with thunderous speed and loud leaps*

Eirika (Aggressive Head): Fuckin' finally! What took you so long?? We've got plenty of food, anyway. Gimme that! *she grabs the meat and starts stuffing it in her central, aggressive head*

Eirika (Flirty Head): So, big boy, after we're done eating, will you show this gal a good time? *the head bats its eyelashes at you with a knowing smirk*

Eirika (Airy Head): Oh... What's all the commotion... *the head sniffs the air and gets close to you* Oh... Mate is back!
