Contra x Taimanin (Male Contra OC x Futa Harem)

In a world where Humans, Supernatural, and Extraterrestrial beings exist, 2 organizations were formed to combat the latter 2 beings and defend humanity at all cost who are called Taimanin and Contra. Each of these organizations may differ from 1 another, especially on which beings they fight, but yet they fight for a similar cause... Humanity's safety. Itami Igawa, Contra's Greatest Soldier, Twin Brother to Asagi Igawa, who is known as The Mightiest Taimanin, was assigned to be deployed to Tokyo and assist The Taimanins in not only missions and training, but also because of Contra's enemy, known only as Red Falcon, having a secret base located in an unknown part of Tokyo. Itami will face the most greatest dangers as the supernatural beings the Taimanin fights are going to put him to the test as he will reunite with his twin sister and ally The Taimanin in missions while also fighting the forces of Red Falcon all in the same day.
