- Nice Job Breaking It, Hero!: In the fifth trial, she does this by refusing to vote due to not being sure who the killer is. What she didn’t know, is that Franziska von Karma had taken control of the trial, and wanted there to be a vote quickly so that the game could be officially messed with. However, because Yoruko convinced the others to join her in her refusal of voting, the plan didn’t work and Franziska got executed even though she didn’t actually kill anyone.

Franziska von Karma
'''Ultimate Prosecutor

- Kill the Cutie: He was one of the most innocent and kind hearted in the killing game. So it was only a matter of time until he was killed. When it happened, it was gut wrenching. …. Physically and emotionally.

Ultimate Swordsman

"Red Crewmate"
Ultimate Crewmate

He was the second killer, killing Toon Link when he remembered his true nature as the Ultimate Impostor. He also gained a pet named Mini Crewmate who looked just like him, but smaller. Red, before his memory was returned, treated him like a son. However, once he knew who he really was, he discarded Mini like trash.
- False Friend: Because Red was really The Impostor, he was never really friends with any of them, even if he didn’t know it until mid chapter two.
Toon Link
Ultimate Sailor
Toon Link was the Ultimate Sailor. He was the second victim, being killed by Red/The Impostor, due to his despair state. Toon Link was targeted as he was an easy victim because of the motive given to him. This motive caused him to randomly fall asleep at times he could not control, giving Impostor the perfect opportunity to strike.
- Kid Hero: He fits this to a tee.
Mao Mao
'''Ultimate Sheriff
Mao Mao is the Ultimate Sheriff. Due to trauma caused by the first trial, he developed a split personality by the name of Pow Pow, who served as a wiser and kinder figure to both Mao Mao and the participants as a whole. He is one of the six survivors.
- Split Personality: He gained one after the events of the first trial. Unlike most of the examples, neither Mao Mao or his split self Pow Pow were evil or played for drama. Pow Pow acted more at first as an annoyance and eventually a strong friend to Mao Mao and the rest of the group.

But at the cost of killing his redemption arc, along with his good relationship with Yoruko.

Former Ultimate Merchant

- The Determinator: Teruya no matter what stays determined throughout every situation in the killing game.
- Failure Hero: Teruya tries his best, but no matter what he does, he can't seem to save anyone throughout the course of the Killing Lockdown. . until his sacrifice at the end, which may have ultimately made it so no one else besides him and Franziska would have to die.
- Hair-Trigger Temper: Gets one thanks to the second motive, due to becoming bipolar.
- Horrifying the Horror: Pulls this when he's pissed off in Chapter 2, scaring the mascot of the killing game and basically everyone when he's pissed off, so much so that Ralsei's scared at him for the entire rest of the killing game.
- Sanity Slippage: Less so then in the fourth chapter of SDRA2, but he does NOT take the fourth trial well in the least, possibly because one of his closest friends ended up being the blackened due to Nikei's manipulations.
- The Promise: Teruya promises after the third trial that he will end the killing game with his bare hands, like a certain other green-haired killing game survivor. This comes to play in Chapter 5, as he ends up coming up with a plan to end the killing game himself with the help of Franziska.
- Token Good Teammate: The only participant of the Killing Lockdown who was not a member of Deleo, as revealed by Yoruko in the final trial.
- True Companions: Acknowledges that he considers Yoruko this in Chapter 3, and also believed this of Marin, which made Chapter 4 hurt all the harder. . .
- You Wouldn't Like Me When I'm Angry!: Ends up playing into this in Chapter 2, due to his bipolarity and Teruya when he's angry tearing apart Aotokage, violating a rule, and scaring her so much as a result that she didn't even try to punish him as a result.
