It's been a while, review time.

On the colonised planet of Terra 2, only men exist, only six men survived the original landing and cloning tech has allowed the men to exist for 300 years, in Japoness, we join Otaru, an odd jobs guy who during a routine run in with unwanted boyfriend Hanagata, unlocks a female android called Lime known as a marionette, but unlike other marionettes, Lime has human emotions which arrives just in time to deal with an invasion from Gartland, joined by Cherry and Bloodberry, Otaru sets off to defeat Gartland preventing the invasion of Japoness, all the while learning the secrets behind the last remaining woman Lorelei and the secrets behind the maiden system that are also in the enemy marionettes.
True fact, this is the first manga I ever finished and it would take twenty years to finally watch the tv series, the show is an under rated under appreciated gem, it has quite an interesting lore and really begs the question of what really happens in an all male society and when you introduce the female gender in it's purest form and not the fakes the original marionettes were, it helps that we got the music of Megumi Hayashibara and the character designs are my favourite in all of anime for it's vibrant colours and pleasant aura, even the dub turned out reasonably good.
Unfortunately the further you go into the sequel series, the weaker it gets, so the first and maybe second season J to X should be plenty, all I'll say is, don't look up Saber Marionette Z.
Final Verdict: this should've been included in the essential 90s anime experience right up there with Slayers, Saint Tail, Wedding Peach and Outlaw Star, it's worth your time.
