The Three Princes and Adarna (2021)

Three brothers set out on a quest to find a never-before -heard legendary bird, the Adarna, that could heal their ailing father... or so they were told.

It is said to live in the most dangerous place in the kingdom, Mt.Tabor; so they must first seek a guide who could hopefully make this journey much less treacherous.

For this, they find Addie, a girl who claims to be a capable(?) guide for the group. Together, they set off on their quest to obtain the Adarna bird.

Addie: "Actually, you never did tell me what you needed-"
Diego: "You mean to say that you have been traveling with us without knowing...?"
Addie: "Yeah, seems that way, hehe..."

... They'll be fine, right...?
