1. Asami / Finder series. I assume he has learned survival skill and we have a higher chance of being rescued by his men.
2. Lucaon / Royal Servant. He has supernatural power and we can manipulate that strength to help us survive on the stranded island.
3. Naoya / Hidoku Shinaide. He has medical knowledge and smart. His brain can help us to make strategy and survive before the rescue comes.
Obviously Azumaya "Chunta" Junta..!!!! ヾ(☆▽☆)
You ask why..??
Because of this...!!!
