NA Localization:
The mythical beast called the griffin once roamed this world.
Devouring both man and horse, rumor said there was no beast more brutal.
The spawn of such a brutal beast and a mare is called a Hippogriff.
...An animal that mates with its prey doesn't exist.
That's why a hippogriff is essentially an impossible magical beast.
...Or so they say.
"Then, then why are you my steed?"
"Queee!"
(Translation: I think, therefore, I am. Fantasies can also be reality.)
"You don't know? Yeah, I don't really know, either."
"Quaaa!"
(Translation: Oh! The world is filled with fantasies!)
"It's fine, it's fine. Because I love you! See? I'll give you a big hug!"
"Gueee!"
(Translation: Please listen to me.)
Fan Translation:
The Phantasmal Beast Griffin, once roamed the world.
They are said to had been atrocious beasts that feed on humans and horses.
It is said that a hypogriff is born from a griffin and a mare.
……An animal that mates with its prey doesn't exist.
Therefore, this hypogriff is in itself, an impossible beast.
……However,
"Hey, why are you my steed?"
"Kue-!"
(Translation: "I think, therefore I am. Illusions are, again, the truth.)
"You don't understand? Yeah, I know right! I don't understand either!"
"Kua-!"
(Translation: "The world is filled with illusions!")
"It's alright, it's alright! Because I love you! Here you go, I will give you a hug!"
"Gue-!"
(Translation: "Are you even listening?!")
