Good タイトル for a western manga?

I know, I'm posting this on ランダム and not manga, but normally the 回答 come もっと見る quickly here than anywhere else. I think anyone who's asked a 質問 here will understand.

Anyway, I'm creating a slightly もっと見る western-style マンガ (as I'm from the US), and I can't think of a title. It's about a teenage girl who can talk to animals. Her name is Yoshikawa Natsumi, and she travels with three other people her age. Since she talks to animals, she's constantly visiting forests, caves, etc....

The antagonist is a person known only as Noboru, and his ultimate plot is to tear down all animal habitats and replace each one with something for him (a castle, a mansion, skyscrapers, etc.). Natsumi's goal is to protect the ハート, 心 of all animal habitats, a gigantic forest (I might use the タイトル for the name of the habitat, depending on the suggestions), while fighting to restore the rest of the habitats as well.

I may または may not use any of these suggestions, and might post a promo chapter on ファンポップ eventually. Any ideas?
