- Complete Monster: Ted Chikatilo, known as the "Million Killer" and owning the title of Ultimate Pyrotechnic, is a member of Ultimate Despair and an infamous bomber who's one of Future Foundation's most wanted criminals. Chikatilo has a fascination with explosions and violence, using the Tragedy to his advantage to turn people into "beautiful fireworks". Responsible for a number of bombings and coming off his latest killing spree where he murdered a platoon of Future Foundation agents, turning one into one of his "art pieces", Chikatilo sets his sights on Killer Killer for bragging rights. Knowing Future Foundation was planning to lure him out, he tried to trick Takumi and Juzo, disguised as him, into fighting each other before coming out and attacking the two. When Takumi managed to thwart his attempt, Chikatilo became more aggressive, killing countless people around him, before trying to blow up Takumi, his partner Misaki, and anyone around in a wide range explosion. A narcissist of carnage, with thousands of deaths to his name, Ted Chikatilo is one of the worst criminals in the world of Danganronpa.
- Like You Would Really Do It: Makoto Naegi is seemingly found dead at the end of Chapter 3. Considering Naegi is the main character of the anime that the manga ties into, very few people bought it, to the point that his death was disconfirmed not in the manga itself, but the official timeline released on the website.
- Magnificent Bastard: The titular "Killer Killer", Takumi Hijirihara is a suave assassin who uses his skill to protect the world from other killers. After surviving a massacre committed by Mukuro Ikusaba, Takumi joined Future Foundation's 6th branch, partnering with Misaki Asano to investigate and stop prolific killers. With his ability to enter the killer's mindset, Takumi is able to figure them out before grading and killing them with a similar method to the killers' own MO. When his old friend Shuuji Fujigawa returns and takes Misaki and places a detonator on her neck which will activate a massive bomb killing millions unless Misaki is killed, out of jealousy of their budding romance, Takumi outs himself as Killer Killer, willing to become a fugitive to protect Misaki and defeats Fujigawa, deactivating the detonator with his cutting skills before running away taking Misaki with him to be with her in hiding.
- Moral Event Horizon: This manga reveals that Junko Enoshima and Mukuro Ikusaba crossed it even before The Tragedy of Hope's Peak Academy. Shortly after Mukuro returned to Japan, she massacred the entire student body of Giboura Junior High on Junko's orders simply to prove she hadn't gotten rusty.
