I hope that helps ^_^

If you don't mind lots of violence these manga have that type of storyline;

Battle Royale - the twist is only one of the students can survive & they're pitched against each other http://myanimelist.net/manga/142/Battle_Royale

Suicide Island / Jisatsutou - People who are suicidal are just dumped on this island to get on with things rather than waste money caring for them. However, some people get over their suicidal urges and want to leave & have to learn how to survice http://myanimelist.net/manga.php?id=11434

Hohzuki Island http://myanimelist.net/manga/5119/Hohzuki_Island

These are more romance/ecchi, but still stranded on an island;

Let's Lagoon - Boy & girl castaway on an island http://myanimelist.net/manga/15165/Lets_Lagoon

Nagasarete Airantou http://myanimelist.net/manga.php?id=1086

Cage Of Eden Characters
