Nekus

Story: The plot is just like the synopsis says, 4 cute high-schoolers happen to be in a plane crash and end up together in a deserted island, thankfully one of them Homura (the main character even if all 4 become pretty important) is a survival specialist and carries the others at the start. The story progresses nicely and doesn' get repetitive even after 66 chapters, it is generally light-hearted but with som nicely put heavy/scary moments. From a realist standpoint, they sure are really lucky sometimes but it's 100% believable.
Art: The Art is really pretty weather they are shoving a girl's body or a dying animal. Nothing else to say really just go look at it and you'll see that it's good.
Characters: At first the other 3 girls are kinda useless and bland but as the story progresses their personalities become better defined and we see their talent coming to light in different ways and they start to become useful, necessary even which is a nice touch.
This manga is overall above-average and I read it all (66 chapters right now) in a row without being bored at any point. So, in the end, my suggestion is to read the first chapters, if you like good because it only gets better if you don't, well the overall feel of the work doesn't really change so it might not be for you.
