• Portal — yes Aposimz (stylized in all caps), known in Japan as Ningyō no Kuni, is a Japanese manga series written and illustrated by Tsutomu Nihei. It was serialized in Kodansha's manga magazine Monthly Shōnen Sirius from February 2017 to August 2021, with its chapters collected in nine tankōbon volumes.

The series takes place on an artificial celestial body known as Aposhimuzu, which is 200,000 kilometers in diameter. Most of the planet's volume is occupied by its core, which is covered by a superstructural shell. Five thousand years ago, people who lost a war against the inhabitants of the core were exiled to the surface, a cold and harsh environment. Surface dwellers face both the rapidly spreading Frame Disease, which slowly converts normal humans into biomechanical, zombie-like beings, and native biomechanical creatures known as automatons. Certain people have been transformed by special "codes" into Regular Frames, beings composed of a substance called placenta and fueled by Heigus Particles, which renders them biologically immortal and makes them stronger and more resilient than normal humans. Regular Frames are also able to assume an armored form, and most have a unique special ability or weapon. These Regular Frames are highly revered by normal humans and are often leaders and protectors in their communities.

• Etherow • The sole survivor of the White Diamond Beam settlement after the Ribedoa Teikoku destroys it. After being transformed into a Regular Frame, he seeks revenge upon the Empire. His armored form is colored in deep red with stripes of white and features a miniature railgun embedded in the left forearm known as an EBTG, which allows him to fire a variety of ammunition from his body's own solidified placenta to the incredibly powerful Anti-Megastructure Bullets. • Taitānia • An intelligent automaton who provides Etherow with the code that transforms him into a Regular Frame as well as seven Anti-Megastructure Bullets (AMBs). She journeys with Etherow as his guide and confidant. Her normal form is that of a small four-legged creature, but she can temporarily assume a humanoid form. However, this transformation consumes a large amount of energy, and she is only able to change once a day. • Keisha • The princess of the underground settlement of Irufu Niku and a Regular Frame who eventually joins Etherow and Titania. Her armored form possesses a staff weapon that can extend to great lengths and is able to channel electricity. • Wasabu • A Regular Frame and former member of the Rebedoa Empire's Reincarnated who joins Etherow's group. As a Regular Frame, Wasabu is capable of reinforcing himself in armor. He is only able to fly.
