Rachel

''"Close your eyes... Now imagine there's nothing there... No rock roof... Just the sky, and beautiful shining specs of light." - ''Rachel to Baam

Rachel is Baam's best friend and an Irregular. However, she did not open the door herself, she merely went into the tower when the door opened for Baam. Per-say, she is only an Irregular by namesake. She made the decision to climb the Tower in order to see the stars in the sky at the top. She is the first known Irregular to be assigned the Light Bearer position.

History
Rachel's life before she entered the Tower is as mysterious as Baam's. Her age and birthplace are completely unknown. During the time she spent with Baam, she taught him everything he knows.

She also taught Baam a board game, which he proved to be fairly good at, and told him that the place "above" where she came from had lots of people who played it.

Rachel has a major obsession surrounding the stars in the night sky and told Baam all about them. At some point or another, she told Baam the story of a man who loved a star so much that he started building a tower to reach it.

In one of Baam's flashbacks, there was a scene where Rachel's hair was being pulled by an unknown person.

Appearance & Personality
Rachel is a short girl with primrose colored hair and freckles. She wears pink skirts and brown long sleeved shirt under it, with a red ribbon tied around her waist and behind her back.

Baam recalls that Rachel is a tomboy who likes to play pranks when Black March asks him about her. He doesn't describe her as exceptionally pretty but that says she is a good friend.

Rachel's obsession with the stars is strong, so strong that she can't sleep at night, but she has doubts due to Baam following her.

Part I
In the 1st test of the Evankhell's floor, she meets Androssi Zahard and Akryung. They form a team which proceeds to kill everyone else in a 30 minute death match, facilitated by Quant for their initial Evankhell test. Her team is then transported to the Crown Game arena. They enter the final round of the Crown Game, in order to defend Baam's position on the throne. Rachel is attacked by Hwa Ryun, but Baam jumps off the throne in order to save her, causing himself to be knocked out by the blow intended for Rachel.

Rachel visits Baam while he is unconscious and meets Koon. She asks him about the legend of the Tower, and tells him that she always had dreamed about reaching the top of the Tower and looking at the starry sky. She asks Koon not to tell Baam it was really her he had saved.

Koon keeps her promise and tells Baam that the person he saved is not Rachel. However, Baam sees through this trick. He wonders why she wants to see the stars so much, because to him, she is 'more important than anything.'

Rachel assumes a different name, Michelle Light. She is positioned as one of the 'Best Seeds' of the Light Bearer group. She is shown to avoid Baam, taking her lunch out to go, and not even caring if this costs extra points. While talking with Androssi in the bathroom, Rachel begins to doubt why she is trying so hard to stay away from Baam. She has a dream where she is looking at the stars and sees Baam, and invites him over, but Baam is surrounded by all his other friends and ignores her. She is quite distressed by this.

She is then put on Team B for the hide-and-seek test, the same team as Baam. She helps manage the team with the other Light Bearers, until Ho shows up. Ho lures Rachel out of her lighthouse by telling her that someone was targeting Baam, and then holds her hostage to use her as a bargaining chip against Quant and Baam. When Baam refuses to budge, Ho stabs Rachel, causing her to scream in pain. However, Baam is able to stun Ho and rescue Rachel. Rachel tells Baam not to chase after her before passing out. She was given treatment for her injury, but Yu Han Sung prevented her from getting proper medical attention. As a result, her legs were seemingly disabled.

Later, in the Submerged Fish Test, she is placed in a bubble of Shinsoo with Baam. They are attacked by the Bull, which attempts to destroy their bubble. Rachel relies on Baam to protect her from it, but after he kills the Bull, she unexpectedly stands up, and pushes him out of the bubble saying, "Sorry. Baam. Here you need to die."

After she came out of the submerged level she was confronted by Rak who inquired Baam's whereabouts, she replied breathlessly that Baam tried to protect her from the sudden appearance of the Bull and is down there, implying that Baam died trying to protect her. Later when Lero-Ro affirms Baams death she faints and is carried to her room to rest. At night however she was sentient of Hwa Ryun visiting her and opens her eyes while Hwa says: "congratulations Rachel, for becoming the heroine of the story" implying all that her actions were an act to gain sympathy from others.

Shortly after that, a flash back shows Baam chasing after Rachel. Rachel said she will enter the Tower and asked Baam to forget about her. She was then transferred into the Tower. Rachel met Headon where Headon explained how she wasn't chosen to enter, Rachel refused to believe this, so Headon offered her a simpler version of the Ball test Baam took in the beginning, to which Rachel replied that said she didn't want to die. After that Headon said she should move out of the way because a guest has arrived. Baam arrives and agrees to take the test, while Rachel watches through a one way window. Rachel was screaming "Don't do it" to Baam over and over again, but she was in a barrier at the time and couldn't be heard.

After Baam's test was over, she asks Headon why Baam was chosen instead of her. Here, she implies that Baam has taken everything from her. Headon offers her a trade: if she could fulfil his yet unknown request, he would let her become the heroine of this story. Headon prepares her with Akryung and Yu Hansung with Hwaryun. After this, the flashback ends with Rachel going back to sleep. Before Hwaryun leaves, she asks why Rachel is going to such lengths to see the stars. Rachel replies that she's afraid of the night(Baam).

Afterwards, she appears along with the other Regulars as they pass on to the next floor.

Powers and Abilities
Rachel is only an Irregular by namesake. She is not quite up to the usual standard of Irregulars, because she lacked the strength to open the gate herself.
