Reina: "Take me too. ♪ "
Chirp: "Senior, good mooorniiing!"
Reina: "Good morning, Chirp. ♪ You're always up early huh?"
Chirp: "That's because I am a weak monster... I get up early to find everyone's weakness. ♪ "
With Pina & Pii:
Pii: "Oh, it's Reina."
Reina: "Yoohoo, Pii, Pina. You doing well?"
Pina: "Reina the old lady in the village was angry. Did you leave in the middle of helping to carry bee hives?"
Pii: "Wow, you ran off in the middle of work? I want to do that too..."
Pina: "Do not imitate her. You'll be a bad bird if you become like Reina."
Kamuro: "Reina always seems to have time... I'm working hard no matter what I'm doing."
Reina: "Relaxing is simply the best. Why not relieve the stress in your shoulders as well, Kamuro?
Kamuro: "Alright, I'll give it a try! By the way... how do I relieve the stress in my shoulders?"
Reina: "...I don't know, a harpy's shoulder skeleton is different."
Reina: "Oh, Miu..."
Miu: "Meeting here after a hundred years! For my pride as a bird I challenge you to a foot race."
Reina: "I am not a fast runner... Don't you have too much of an advantage?
Miu: "Fine then! Arm-wrestling!"
Reina: "That has nothing to do with the pride of a bird..."
Pyhar: "Alright, here's a question for you. ♪ What do you get when you have a reversed 'Harpy?' ♪ "
Reina: "Easy! You get Pyhar, right?"
Pyhar: "The correct answer is... a Yprah!"
Reina: "I'll just say that is difficult to pronounce."
She is required in the "Flap Flap Harpy" scene.
