Music (interview with composer)
I think this anime captures the deeply-seated longing for the mysterious, for the unknown we have inside. Something we can't quite express or articulate. A thing that drives those adventurous enough to get lost into the depths of the abyss, to the point of risking everything, even your humanity, or your life. Herman Melville, said in Moby-Dick: "I am tormented with an everlasting itch for things remote. I love to sail forbidden seas"
In Episode 12, the narrator puts this most clearly: "Longing [of the unknown, of the mysterious] seizes people more powerfully than poison and more deeply than illness. Once it catches hold of you, there is absolutely no escape. That is quite a curse, and yet adventurers all willingly devote themselves to its pursuit. For them, a life without longing is more terrifying than death itself."
Made in abyss, *embodies* this idea beautifully
and yeah it's impossible not to like Nanachi :3
Hmmnaaaa~~~
Also, excellent World building
Loved the sense of Adventure (Wanderlust), and the World building and whole beautiful design of characters and environments. Characters are also very cute, and make cute VRChat avatars which I like :3
