Isla Valentine

"'I didn't wanna annoy you- you're my friend.'" Isla Valentine is the assistant of Dr. K, spending a good chunk of her life with the marine biologist on Mariaqus. Apart from aiding him in the Mariaqus Research Institute, she spends her time listening to the many natural songs that Mariaqus creates, writing down composures and songs of her own and usually fashioning her own instruments to play them.

Personality
Isla is fairly quiet. Despite her difficulty forming bonds, once she has become comfortable with someone she will often show them her music and talk more freely about her interests. It is easy for her to stay calm in dangerous situations and she is hard to anger, but upon loosing her temper she will seem almost like another person all together.

Backstory
After Isla's parents disappeared mysteriously one day with no records or trace of what happened to them, Isla ran away from her adoptive parents. Now living on Mariaqus with Dr. K as his assistant and resident song writer, dedicating her life to music, and of learning more of her birth family.

Trivia

 * A theory is that Isla is actually a lost descendent of the Zeppeli family. There is no official evidence to support this, and is most likely just a joke.
 * Isla is 1 of 4 main candidates in the Re Obscura Dating Sim, a joke game concieved by Soulless, alongside Caedis Alveare, Bunnie and Iris Celeste.
 * During her Bad Ending (achieved if you mistreat Isla), the protagonist is confronted by Caedis, who promptly shoots them once he learns what they did. With Caedis declaring that he's "not the one [they] should worry about", they're then promptly confronted with a barrage of punches from Dr. K's summon.
 * Isla's route has been cited as possibly the second hardest in the game, given that she needs to warm up to the protagonist first before a relationship is even considered, even though the other characters seem to be somewhat warm towards the protagonist, say for Caedis.
