List of Minor Characters in the Four Endings Series

This is a list of minor characters that have appeared or are mentioned in passing in the Four Endings Series, including in its songs, light novels, manga, or other related media.

Eve
Eve was one of the irregular twins birthed by the Master of the Court. Born alongside her twin Adam shortly before the Third Period's destruction in EC 999, Eve was unable to develop a will of her own. After merging with the soul of Eve Moonlit, Eve gained a will of her own and at least some of Eve Moonlit's memories. She later forged a contract with Michelle Marlon before taking up residence in the rebuilt Evil's Theater with Adam, Gammon Octo, Gallerian Marlon, and Michelle.

When Riliane Lucifen d'Autriche and several other sin contractors came to the theater to confront the "Sleep Princess", Michelle went to join Eve and Adam in the interior room of the theater and the three played while the confrontation played out. As Ma resurfaced from within Riliane and absorbed all the contractors, including Michelle, Eve and Adam ran to tell Gammon while he fought with the intruders Allen Avadonia and Nemesis Sudou.

When Ma came out into the exterior room of the theater and attacked the group with lightning, Eve shielded the others from her attack and rebuked her for absorbing the contractors and, by doing so, betraying the Master of the Court who had helped her to survive. Soon after, Adam initiated a Re_birthday, causing Eve as well as the theater, Gammon and Adam himself to be caught in the "reformatting" event and travel back in a loop, presumably to reincarnate as Eve Moonlit.

Luna Hazuki
Luna Hazuki, also known by her nickname of Moon Goddess, was one of the earthlings involved in the creation of the Third Period. In the Second Period, Luna became a mechanical engineer, eventually creating the robot TALOS, a companion robot for the ship Climb One. At some point, she rejected the romantic advances of Gilles Derais. As the Second Period faced destruction due to the spread of HER, Luna and TALOS boarded the Climb One along with 70 other scientists for the sake of finding a new planet to repopulate. As they were brought into reality by Behemo Barisol, they discovered a "new" world, really the destroyed Earth.

Having lost contact with the other spaceships, the Climb One crew realized they were the last inhabitants of Earth and decided to create a new species in the image of earthlings. During this process Seth Twiright, an HER who had secretly boarded the Climb One, instigated the deaths of 62 of the crew members and contaminated the new species to have a possibility of developing HER Syndrome. The remaining crew proposed they reincarnate as gods into the world to guide the humans, unaware that Levia, at least, was an HER.

When Held Yggdra and TALOS disagreed, an ensuing fight occurred and Climb One crashed, Luna being the only survivor while everyone else's physical bodies were killed. TALOS and Held, now having incarnated as gods, agreed to hide Luna's existence and she was assumed dead, forgotten by her compatriots. In EC 999, she was sleeping in a chair within the Climb One when TALOS brought Allen Avadonia to her, and she disappeared from the room. She is described as being an old woman with a mask with wires on her face and liking video games.

Phaser
Phaser was one of the earthlings aboard Climb One. After his death he was made into a forest spirit, using a fox as his avatar. After the end of the world, he accidentally ran into Allen Avadonia and Nemesis Sudou. Having grown resentful of the latter, he quickly ran away from them.

Rin
Rin was a girl living in the Fourth Period together with her mother. During her teenage years, she developed a crush on a boy while riding on the same bus as him. Due to her shyness she found herself unable to talk to him, but still enjoyed the ten minutes they shared during her bus trip to school. She is represented by the Vocaloid Kagamine Rin.
