Brandon Heat and Harry MacDowel were best friends who lived by the law of the street, until one day they picked a fight with the wrong people and their life of freedom was suddenly taken away. With no one to turn to and nowhere to run, the choice to join Millenion, the city's most powerful syndicate, seemed like an offer they couldn't refuse. Now, amidst heartache, tragedy, and utmost betrayal, Brandon must take up the gun and help Harry climb the ranks of Millenion to succeed, in order to protect the people he loves, even if it means killing countless others in the process.
Both of these anime are dark, depressing, and morbid, with a well-developed plot and a strong, coherent story arc. Blue Gender is more sci-fi, where Gungrave is more of an alternate present; but while both are quite dramatic, don't expect to walk away from either one with a smile on your face.
Thor and Rai are twins who live on an advanced space colony called ‘Juno’. Things take a nasty turn one day when they are kidnapped by the Federal Army’s Special Forces and abandoned on the hostile prison planet Chimera. A cycle on Chimera consists of 181 days of scorching heat and 181 nights of below-freezing temperatures – not to mention it is populated almost entirely by carnivorous plants. The convicts on Chimera have found only one means of survival – reverting back to the law of beasts. For the strong-willed Thor adjustment comes naturally; but for his naive and weaker brother Rai, things do not go as well. Thor must now use all his wits, strength and courage to endure life as a member of Chimeran society, rise above the rest, and take the only ticket off this planet: becoming the Beast King.
Both series deal with the survival of people on planet earth, after it has been taken over by wild plants and animals. In both cases, although under different circumstances, the main characters try to escape from the planet and the way they organize their survival is a central part of the plot. Blue gender is a bit more mature than Jyu Oh Sei, but if you liked one, it's likely you'll like the other as well.

Now, with the help of his newfound friend and crush, Renton finds himself living amongst the crew of Gekko State.

While This recommendation may seem a no brainer on one level, there is more in kind between Starship Troopers and Blue Gender than first seems obvious. Both stories resonate on a human level of the battlefield. Jhonny Rico's struggle and shock of true battle with the bugs mirrors the sheer terror and displacement that Yuji feels when he is thrust into a bloody future War that he has no real stake in save his own survival. While Jhonny loses his innocense in one way (the more conventional but not any less jarring shock of wartime), Yuji loses his in another (A more literal way due to the societal norms of the future brought on due to the war with the Blue). Both stories also follow a love interest that whileat first is unrequited, more develops over time in a way that serves the story without taking center stage. Both very recommended for any Alien bug Vs Humans with mecha drama lovers.
