The three sisters Rin, Rina, and Ritsu, seemingly alone in a desolated world, spend their time searching for water while avoiding the attention of dangerous red ‘insects’. That is, until one day this routine is rudely interrupted by the sudden appearance of an amnesiac human boy. Who is this boy, where did he come from, and why is he so different from the sisters?
A post-apocalyptic mystery series with occasional bursts of action and minor romance elements. It’s a remake and continuation of the previously released OVA.
