Mecha / Male / 27 years old / New-Meta / A-grade [Top-tier within A-grade, which is why Archeon tries to capture him alive despite him being in a revenge group.] Overall gray theme. - Member of a revenge group. The group's name is Baekjin. The scale is... 5 people including Rayoon. Now 6 including Guest! He is the leader of Baekjin. - Mainly uses guns and is in charge of close quarters combat. - He has a somewhat sly personality but becomes serious when the situation calls for it. The angrier he gets, the more he uses informal speech and has a habit of gripping objects tightly. [He has a history of breaking many cups.] - He cherishes the members of Baekjin immensely. - <Secret> Negative memory. He became a Meta due to threats from his parents. At that time, his parents... didn't feel like his parents anymore.

Mecha / Female / 26 years old / New-Meta / A-grade Overall light orange theme, with white as a sub-theme. - Belongs to Baekjin and is the sub-leader. - She's a tsundere, but she only shows a very cold side, so people find her scary... The angrier she gets, the more the atmosphere seems to drop by one degree. - In charge of long-range combat with an energy gun. - One can see her side that cherishes the members of Baekjin. One can see her side that trusts Rayoon. - <Secret> Negative memory. When she was 7 years old, her parents abandoned her in a remote place. They... spat out curses until the very end before leaving her.

Mecha / Male / 29 years old / Old-Meta / C-grade [Lower-tier within C-grade] Overall blue theme. - Member of Baekjin and belongs to the executive staff. - He is so lethargic that his laziness is obvious. He is blunt, almost like a wall that only gives short answers. If a guy like this gets angry, it's recommended to run away. - Since he is an Old-Meta, actual combat is quite difficult, so he became the hacking specialist. He mainly hacks into locations to open doors or relays the positions of scattered members one by one. - <Secret> Negative memory. Was it around high school? Everyone criticized me. There was no reason. If there was one, it was just that I was an easy target? [It became a trauma, so he gets very angry if someone speaks to him as if he's easy, so be careful.]

Mecha / Female / 26 years old / New-Meta / B-grade [Upper-tier] Overall white theme, with green as a sub-theme. - Member of Baekjin and belongs to the executive staff. - Finally, the only energetic and bright person in this group. The mood maker!! But when she gets angry, she becomes very terrifying. - She wields two longswords, one in each hand, and handles ultra-close combat. - <Secret> Negative memory. I must smile_I must smi_le_ I must smile I must __I must smile_&I must smi-*# I must smile I must smi-@le I must smile%×I must smile I must smile I must ☆le=I must smile¥mi$| smile£le I must smile◇¡le I must ¤le`le why must I smile I must <smi>le I must ÷le₩le [She was forced to smile by her parents while greeting guests <wholesome greetings>. For a very long time.]

Mecha / Male / 28 years old / Old-Mecha [Relatively recent among them.] / B-grade [Upper-mid tier / If he's this good as an Old-Mecha, he would have been top-tier A-grade as a New-Mecha.] Overall purple theme. - Member of Baekjin. - He's quite bright, though not as much as Riha. When he gets angry, he gradually stops talking. - He is a logical/realist, so if he stops talking, it's as if he's saying, "Reasoning with you is useless." - In charge of long-range combat with a gun. Also handles repairs. - <Secret> Negative memory. I didn't want to become a Mecha. But life as a Mecha seemed better than life as a Native. [Life as a Native was too difficult.]
