After the most recent class trial had come to an end, a new floor of the school soon opened up. As they explored it, they discovered a botanical garden, a dojo, a biology lab which was locked and three classrooms. They also found that the stairs ended of the fifth floor. They also discovered that one classroom was completely wrecked up with blood on the walls and fat. It made the group sick just by looking at the room.
They all soon joined together in the cafeteria to discuss their findings, they came to the conclusion that what happened in one of the classrooms was because of the 'Most Despair Inducing Event in Human History.' "I'll try and figure out what happened in that classroom." Kyoko said surprising everyone. "This again. Where are you going in these most critical times? Where were during the Hifuma and Celeste, and the Sakura cases?" Byakuya asked. "Isn't it about time you told us?" he asked. "Told you what?" Kyoko asked. "Who you really are. Who exactly are you, Kyoko Kirigiri?" Byakuya asked her.
"I'm sorry. But I cannot say." she replied. "What a laughably unlaughable joke. Do you really expect us to trust you?" he asked. "I know you won't. That's why I haven't brought it up." she said. "Man, Kyoko's pretty cool." Soul said. "If this is the way you are going to act, we're going to have to restrict your movement. Give me your room key. If you don't want to, then speak up." Byakuya said. Kyoko then stood up and handed him her room key. She then walked out of the room. "What is so important that she has to keep it secret?" Aelita wondered. Just then, the PA system kicked in.
"Attention all students. Report to the gym immediately!" the bear said angrily. Everyone soon arrived to the gym to see Monokuma beating up a fish. "I am so angry right now! One of you have stolen my secret treasure! This will not stand!" he shouted. "Wait! Where's the girl in all the purple? She must have been the one who stole it! She also destroyed a surveilence camera. That goes against school policy! No, you are all responsible! You will all pay!" he shouted as he returned to the podium and it went down.
After the events that had occured in the gym, Makoto had returned to his room only to be called into the bath house by Kyoko. The two soon met inside where she showed Makoto the key she had taken from Monokuma. She then explained to Makoto that he needed to keep Monokuma busy while she tries to finds which room the key opens. Makoto agreed on the condition that she come back alive. She agreed.
Later that night, after distracting Monokuma, Makoto spelt in his bed having strange dreams about being told to stay in the school. He woke up in the middle of the night to see someone in a mask holding a knife in their hand. Makoto then slept again only to wake up to Kyoko. He fell asleep again only to find it morning. He walked into the cafeteria along with the heroes to see it empty. "Strange. Where is everyone?" Usagi asked as thye looked around the school till they found the four students in the gym taking apart Monokuma. "What are you guys doing? That's Monokuma!" Ichigo said. "Its all right." Byakuya said. "Yeah. This things broken." Hiro said. "What do you mean?" Makoto asked. "I couldn't stop thinking about what Monokuma's stolen treasure was last night. I came here to ask him what it was but he was nothing more than a stuffed toy." Byakuya said. "So I called the other students together and we began to dismantle the thing." "Master came up with this genius idea. He said this was our chance to figure out how Monokuma worked." Toko said. As they continued to disassemble it, Hiro soon took out the bomb inside of him. "Ahh! I just found the bomb!" he said as everyone took a step back from him except for Byakuya. "Apparently a standard Monokuma comes equipped with them. They are vibration sensitive." Byakuya said. "Seriously? I can't get my hands to stop shaking." he said. "Also, I forgot to mention. I switched the sensor off earlier." Byakuya said as everyone calmed down.
"So, how did he break anyway?" Luffy asked. "Something bad probably happened to the headmaster. So, we should probably head to his office so we can confirm this has happened." Byakuya said. The group was later seen at the door to the office only to find it locked. "Toko! In under one minute, go and find us a pick ax. There should be one in the shed in the botanical garden." Byakuya ordered as Toko ran to get it. "So we're just going to break the door down?" Natsu asked. "Yes. It should be easy since Monokuma is out of commission." Byakuya said as they saw Toko running down the hall quickly. "There's Toko. Wait, that's Genocide Jill!" Hiro said.
"Here I am! Everyone's favorite serial killer with a shining smile. Kyehahaha!" she said. "So where's the pick?" Byakuya asked. "Pick? Oh, I get it. This girl was suppose to find a pick ax in the garden. That's one mystery solved, now for the other one. Why is there a corpse in the botanical garden?" she said causing the others to gasp.
They soon went to the botanical garden to find a person covered in a white sheet and wearing the same mask as the person who tried to attack Makoto. A knife was seen in there chest. "So, who's body is this?" Eren asked. "Probably Kyoko's since she is the only one not here." Byakuya said. "Let's just solve this by taking the mask off." Genocide Jill said as she ran towards the body. "Wait!" Byakuya said. But it was too late for as soon as she pulled the mask off, an explosion occured setting the body on fire and knocking the girl into a tree which on impact knocked her out. "We need to put this fire out immediately." Byakuya said as they all quickly grabbed bucket after bucket of water and doused the flames of the body. Soon, the body was extinguished but totally unrecognizable except for a wolf tattoo on the right hand of the corpse. "Well, we put the fire out and since Kyoko isn't here, we naturally have to assume it was her corpse." Byakuya said. "No, there's another possibility. A while ago, Kyoko told us of a sixteenth student. A student known as the Ultimate Despair: Mukuro Ikusaba." Makoto said. As they discussed this, they noticed a key next to the right hand. They then took it. "But, what does this key open?" Tsuna asked. "I have an idea about what it opens." Byakuya said as the group headed to the data center where they put the key into the lock and opened the door.
Once they were inside, they saw several screens showing footage from the surveillence cameras along with a door with Monokuma's face on it. As they looked around more, they soon found a television inside with an antenna. But before they could turn it on, a familiar voice was heard. "Oh my! SO you actually found it? Pupupupu! Its been an unbearably long time since we last met!" Monokuma said. "Wait, weren't you dead?" Happy asked the bear. "Me? Dead? Don't go spourting such bearfaced lies! I was playing dead since I saw a bear...in the mirror! Pupupu!" he said. "You seem to be acting like a totally different person." Aelita said. "Of course. I've become a whole new bear. Its been two years since then after all. Also, you are all probably wondering what all this is. Let me show you." the bear said as he turned on the television to show the whole group on it. "Welcome to the most despair inducing television show in history! You see, I have been broadcasting this all over the nation. Every killing, every trial, all part of the despair sowing. But, shouldn't you all be focusing on something else right now?" he asked.
"The class trial. A body was found in the botanical garden, so now we have to figure out who killed them." Kirito said glaring at the bear. "Bingo. I hope you all enjoy it!" Monokuma said as he walked out and the PA kicked in. "A body has been found. We will hold a Class Trial!" he said. After it cut out, Kyoko walked into the room. "Looks like we're in a bind here." she said. "Kyoko! You're alive. Where have you been?" Maka asked. "I've found out a lot of things thanks to you, Makoto." she said to Makoto who smiled. "Wait a minute, if you are still alive, then the corpse in the botanical garden is..." Usagi started. "Yes. The body there is no doubt the body of Mukuro Ikusaba, the Ultimate Despair."
