Vermillion Rogue is an ultimate student at Hope's Peak High and is the Ultimate Scientist. He was best known to be selfish, prideful, stubborn, flamboyant, and intelligent. He is also extremely bossy towards other people and calls anyone in a lower class (normal) peasants. Vermillion was working with Umbrella at the age of 12 thanks to his early talents, but resided after the corporation's stock market began to diminish after being exposed of conducting illegal and harmful experiments. Vermillion is also known to not fully participate in the Class Trials, and rather make snarky and cocky comments as of means of entertainment. However, he also began to see a sudden change of heart, when he begins to reflect from the last class trial he was in: The trial for the murder of Hoth Regal's younger brother. When Vermillion suspects Kooky Poppers, Timmy's older brother, he decides to make a decision and look into the matter. One day, when Vermillion's suspicions were confirmed, he headed towards a table secluded from the cafeteria where Chi Makita, Ann Takamaki, Ryuji Sakamoto, Yusuke Kitagawa, Yosuke Hanamura, and Rise Kujikawa reside having a conversation. He was received with grills and distrust, but brushed it off and asked as to what they fight for and only wants answers from the group other than Chi. Of course they made their feelings of distrust very clear thinking that he's just going to make fun of him and scold him to leave, which made Vermillion ponder a bit knowing they fight for something worth fighting for and thanked them for the answer, taking his leave. Later that day, Rise, Chi, and a whole bunch of other friends decided to follow Vermillion as to see what he's up to, only for their answers of suspicions shatter straight to the ground after witnessing Vermillion on the floor bleeding to death. The group panicked and assured him that help is on the way. However, to their utter shock, Vermillion wastes no time making his dying words out of his blood and writing in Hiragana "tsuki", meaning moon, giving them a hint of who is the murderer. He then asks God to forgive him whole-heartedly before making his last breath, and died of blood loss. Everyone was shocked and horrified to see a changed man die for their lives, and the body discovery announcement broadcasted by Cat Makita played. Chi managed to use the evidence he gathered and connected the pieces together and pinning Kooky as the murderer thanks to Vermillion's dying message as critical evidence, since Kooky is the Ultimate Astronaut alongside Kaito Momota. Vermillion proves to have a change of heart, now knowing his mistakes and forsaking his pride for something even worth better than before, and humbling himself before the Lord.
