Danganronpa Doomful mistake

Chapter 3. Double Check of Hope over Despair Part 3 (Class Trial)

Monokuma: "Now then! Let's start with a simple explanation of the class trial!" 

Kaede: "We know what to do, bear!" 

Monokuma: "Normally I would execute you, but I might hit the culprit!" 

Miu: "Wait, Kaede is the culprit?" 

Monokuma: "You figure it out!"

Keebo: "Where should we start?" 

Shuichi: "To the vote! We all know who's the culprit!" 

Korekiyo: "I didn't kill anyone." 

Tenko: "We will see about that." 

Himiko: "We're nine to one! The majority agrees!" 

Keebo: "Perhaps we should actually start a conversation."

Rantaro: "Alright then, let's see what happened last night." 

Shuichi: "I have an idea! Last night, Kiyo invited Kirumi to his lab. There he took the katana, even with the golden sheet!" 

Kaede: "And stabbed Kirumi in her heart! Killing her!" 

Miu: "I don't think Kirumi would just let herself be killed like that." 

Kaede: "Of course, he fought with her!" 

Rantaro: "And Kirumi lost the fight. Then, Kiyo pushed Kirumi to the wall and stabbed her in her heart." 

Tenko: "And that's how she died! Right Kiyo?" 

Korekiyo: "............." 

Gonta: "Stop being silent, we're speaking with you!" 

Kokichi: "(One of the arguments has something more to it.)" 

Kaede: "Of course, he fought with her!" 

Kokichi: "No, that's wrong!" 

Kaede: "You again?" 

Kokichi: "The culprit didn't fight Kirumi! While Keebo investigated, he didn't find any signs of a struggle."

Keebo: "Yeah, if the culprit fights Kirumi there would be something, however the lab seemed too clean." 

Miu: "She may have been knocked out."

Kokichi: "I doubt it."

Miu: "Why?" 

Kokichi: "(I should show her)" 

Kokichi: "The Monokuma file 3! It doesn't say anything that could knock her out. No blood force trauma or anything similar." 

Miu: "Oh yeah." 

Korekiyo: "What about her stomach wound? With that much bleeding she would have faith for sure." 

Gonta: "Yeah she would. But with that many stabs she might as well die." 

Shuichi: "Her heart wound didn't have much blood. She probably got killed by the stomach wound." 

Miu: "This is why the monokuma file didn't say her cause of death!" 

Keebo: "The culprit probably wanted to use the katana for a fake wound to frame Kiyo for the muder!" 

Himiko: "C'mon! No one else could be the culprit! How did the culprit enter his lab otherwise?!" 

Rantaro: "Maybe what he said wasn't a lie? He may have been knocked out."

Shuichi: "That garbage is most likely to kill someone." 

Korekiyo: "I wasn't lying, we all know that's Shuichi's thing."
