Mikado Sannoji

Personality
Mikado Sannoji is a very friendly man who doesn't wish harm to anyone, not even those who've wronged him. He does his best to assist the class, and provides feasts for them daily, so they don't get lose their fighting spirit.

He believes that everyone has potential to do great things, and often tells people such as Maki Harukawa that they're doing well despite the circumstances at hand, and that if they keep going for it, they'd have a fighting chance.

Mikado also shows himself to be quite intelligent, being able to pick apart loopholes in the rules, using the game to his own advantage. This is shown when he attempts to attack the Monobeast, saying if he used his abilities it technically wouldn't be a violation of Rule 7.

This also shows a weakness in his personality, where he's stubborn and acts on his own constantly. This even leads to his death, as Ren Shirogane wouldn't be able to stab him had he either been honest about his injury, or just stayed in his room for the concert. He does this all to do individual investigations without interruption, and as far as he's concerned, stopped Ren from attempting to kill anyone else.

Before the Killing Game:
As stated by Mikado, he was a very poor orphan in desperate need of help, finding no luck in anything he did. That was until one day, where an orange haired man with "tired eyes" as he described it blessed him with heavenly luck, and made him realize his potential in magic.

He developed these skills with constant meditation and rigorous practice, being able to impress several people. He won some fame by this, but not enough to be heard about by the rest of the students because according to him, he hates publicity.

Prologue:
Mikado was one of the 15 students who arrived, and introduced himself to the others. As they all reached the island, and after encountering their tour guide, Monokuma, he entered the dining hall and boasted he could use magic to create food. To ease all doubts, he rushed everyone out of the room, and quickly made an entire feast out of nowhere.

At the beach party following, he would join a water fight against some other students, along with Maki. He would prove himself a master of several elements. But just afterwards, everyone was called to the hotel lobby, where Monokuma revealed they were trapped on the island and had to get away with murder to escape.

Chapter 1:
The next day, Mikado made a large breakfast with the help of Akane Taira and Nori Akamine, doing it to alleviate some stress and hoping to achieve the sense of comradery they all had before the game started.

After breakfast, Monokuma told them all about the plaza, to which everyone save for a few people, including Mikado, didn't go to. It was during this investigation of the plaza that everyone heard a large roar, and ran out to see Mikado approaching a Monobeast with killing intent. He said if he succeeded, it wouldn't violate Rule 7 because killing it wouldn't directly tie to escape. He was shot in the leg by it, though, and gave up, realizing he'd die if he went further, much to the disappointment of Kaito Momota. He was rushed to the hotel, and was given help by Mikan Tsumiki and Keiji Shinogi.

He was confined to his room, so he wasn't present for the motive being given, and was filled in by Ibuki Mioda, who promised to give him a private concert in his room after the concert that was meant to be held on the beach.

Mikado's Fate and Legacy:
On the night of the concert, he snuck out to the spa in order to do some investigations, but ran into Ren. He immediately saw the killing intent in his eyes, and offered to be the one to die, to which Ren agreed to the plan, and stabbed him. As Ren fled, Mikado used a cord on the door, locking it from the inside, and crawled to the men's changing room, using gasoline to burn himself alive.

He committed suicide in order to stop Ren from being executed, as he didn't wish for him to be executed despite what he did.

His death served as a sudden snap to reality for the participants, and urged certain people such as Rin Satsuki and Setsuka Chiebukuro to notice how weak their safety measures were. This caused future murders to be less easy to create, potentially causing several unsolvable cases to be solvable.

Maki Harukawa:
Mikado is very friendly and supportive towards Maki, urging her to try and befriend everyone despite being very anti-social, and is understanding when she feels unconfident about it. They have a great deal of trust in each other, Mikado believing he would trust her no matter what secrets she was hiding from him, understanding that everyone has secrets. In a Free Time Event, Mikado made a promise to give a magic show at her orphanage, but all of that would fail to come true as his death happened.

His death shook Maki up, making her unstable and willing to kill Ren, in spite of what Mikado died for on the first island. She's reminded by Kaito Momota and Yuki Maeda that Mikado wouldn't want her to do anything rash, ending her bout of anger.

Akane Taira:
Mikado is impressed by Akane's motivation and perseverance she has about her job. He goes as far as telling her that this will to always do her job would aid perfectly in learning how to use magic, and even offers to teach her the basics of magic. They both also share a very similar past, realizing they were helped by the same orange haired man.

Ibuki Mioda:
Mikado and Ibuki find even ground being very ready to try and cheer people up. Mikado regrets not being able to show up to her concert, but understands why he should stay where he was, causing Ibuki to offer him a private concert, which he happily accepts. Ibuki calls him 'Magic Man' as a nickname.

Kaito Momota:
Kaito encouraged Mikado to stand up to the Monobeast, but Mikado withdraws, causing Kaito to be disappointed. He later tries to plan a surprise attack on the Monobeast with Mikado's help. Mikado rejects this, saying he realized it was basically a war machine, and that just a surprise attack wouldn't be enough to stop Monokuma's power over the group. This causes Kaito to ever so slightly consider him a coward.
