Introduction
After an airplane crash during a school trip, Oribe Mutsumi and her classmates were stranded on a seemingly deserted island. Mutsumi found the other survivors, and used her wilderness knowledge to help them. She expects that they will be rescued in about three days, which doesn't seem so long to endure. However, she didn't account for the fact that the island is populated with gigantic killer insects. Her knowledge of butterflies, wasps, and more may be the only thing that will help any of her classmates survive to be rescued!

Oh this is just delightfully abysmal, another generic surving anime for the surprise of everyone! but i don't know what could possibly be more more legally blind that adding a lot of shock value involving insect sex.

First and most importantly: skip this OVA and watch the movie instead, since this OVA is literally the same as the movie (this OVA starts at the scene roughly 15 minutes in).
Not much to review about this. It's basically a gory, insect-rape doujinshi and it's pretty bad, even by that standard. With too much focus on awful cliched characters and a story that isn't even explained, unless you read the manga prior to watching, you're in for dull character interactions and several shots of insect rape/gore. It's harder to care about the story or characters when you get dropped in mid-story and it ends with a cliffhanger to the next scene.
In short, if you're interested in watching this for a story, skip the OVA and just watch the movie. If insect rape is your thing, there are a few short scen…
