In 2031, ancient relics were found that proved the existence of an alien race, and they bore a chilling message: mankind will eventually be fated to fight the Hadeans, and their loss would mean the destruction of humanity. Now, twenty years later, man lives side by side with mutated creatures that spawned from the waters where the relics were discovered. The Neo International Defense Force (N.I.D.F.) was formed to protect the planet from any threats that may occur as a result. Chief scientist Yuno Rukina has been sent to find the Book of the Dead. But upon finding it, vast swarms of insects and large monsters appear around the globe; the Hadeans have finally arrived. As members of the N.I.D.F. try to contain the threat, Aiba Shu is mortally wounded; to save him from death, Yuno plunges the Book of the Dead into his chest, transforming into the Necrodiver – the messenger of humanity. Armed with integrated weapons and assisted by powerful guardians, Aiba must defend the planet against the Hadeans and keep his revenge against the human who betrayed her own race.
In the early 21st century, certain people are exhibiting signs of B-cell growth, a condition that is incurable. Yuji is one of these, who chooses to become a "Sleeper" -- a person who is put into stasis until a cure can be found. The tranquillity of Yuji's sleep is interrupted 15 years in the future, in a very different world. Giant bugs known as Blue have invaded the Earth, eating its resources, and.. human beings. Now all Yuji can do is escape through the city with the ones who saved him from his inevitable death, towards Second Earth... mankind's new home in space.
Blue Gender and Kiss Dum are remarkably similar in so many ways. Giant creatures swarm the planet and leave a tattered landscape behind with few survivors. A lone protagonist must fight his way to survival, though in Kiss Dum the lead isn't nearly as whiny or powerless as in Blue Gender. Regardless I strongly believe fans of one would enjoy the other.

this anime is defienently something for you if you liked the other. They might seem a bit different at the begining, not to mention the differnce in production year. But as you get into the show, the similarity of these will begin to show.
The only difference there is is probably the superpower vs. the mecha thing. otherwise these will fit perfectly.
but since i don't want to spoil anything i can only say that if you love the whole "vengeance-theme" as well as the "love-theme" in one of these, then the other will certainly hit spot on.
So i higly recomend these.
