This new light novel series, Planet of the Orcs, has humanity as a minority in a majority of Orcs and other monsters and humanoids. While Light novel series like Overlord, Re: Monster and others, the main character is the antagonist, in this Light Novel series, the main character, seems to be the hero, that has been sent to 13 previous planets (alternate reality worlds) to free humanity from Monster Oppression. Light novel series that have multiple planets (or multiple alternate reality worlds) are like March of a Parallel World Rhapsody, Shield Hero, Monster Paradise and Mechanical God Emperor.
I imagine that author chose current title from the Planet of the Apes (1968) franchise series of books, movies, tv series and comics.
The first volume of this new series has 160 pages (on the short side) and 7 chapters with a bonus story. Currently only 2 volumes have been published in English. The main character is a hero that has been sent to 13 worlds before he was summoned to this the 14th. world. Hero does not have any money, weapons and information about this 14th (Orc Planet). No one has even told him that here, Humans, are a minority.
While this series focuses on the human minority, the point of view of the Monster or Humanoid Orcs is portrayed by an Orc called Black Dog.
The controversy, treachery, depravity and corruption of humanity are described by the author in this first volume. It's as if, the human minority would prefer to be conquered, enslaved and annihilated by the Orc majority. Humanity presents a divided front (worrying more about the control of power within the humans than to end the oppression of the Orc humanoid majority.
Author writes a lot about the power struggles of the minority. If this is the 14th. world that the hero has gone to, in 10 years, I do not understand why, the author explains so much about people that are not only not relevant, but unable to rise from the tyranny of the Orc majority.
