Saruyama Kenichi Takes Control (Rewrite)

The story is about Saruyama Kenichi, a boy who, due to a certain incident, receives the ability to look at alternate realities. After gaining this ability, he realizes that he is nothing more than the secondary character of an ecchi anime, whose only role is to be the perverted friend of the protagonist. With renewed determination and the help of a convenient system, Kenichi resists his future destiny as the protagonist's loser friend, but it is not going to be an easy road. In addition to perverts and aliens, the world in which he finds himself is slightly different from the one he saw in other realities. Will Kenichi overcome all difficulties and gain control of his own life?
