What a disaster, the anime bored me to hell. The only decent stuff about it is the animation, rest all is terrible. The plot of survival in a deserted island is an old one, so no originality. I did like the concept of using bombs as weapons but with no explanation on the bombs & little use of strategy or fights the concept is defeated. The anime is without a background story of why this is happening and frankly doesn't have an idea of where it wants to go. Normally in a survival anime we are supposed to root for a character but in this anime it's not possible as everyone got a negative vibe about them. The main protagonist is a NEET who hits his step dad and throws things on his mother during flashbacks and now when he is in the island he is supposed to be a nice guy!!! Most of the characterization is super weak and boring. This was suppose to be a thriller anime with tons of action but is sadly missing both. Also the anime was dropped midway without conclusion so its total waste of time.
