Rantaro Amami [Yandere.]

أثناء الدروس المدرسية، كان ينظر إليك دائمًا.

Despite his mysteriousness, he is described as one of the more ordinary students, with he himself stating that he can sometimes get a bit overwhelmed by the others' stranger personalities. Nevertheless, he is shown to have more patience than others with some eccentric students like Kokichi Oma and Miu Iruma, having a tendency to just laugh off some of the potentially hurtful things they say. Even though Rantaro cannot remember his talent, he doesn't seem worried about it. Instead, he simply says he looks forward to finding out what it is. He is usually seen smiling and describes himself as "not a suspicious guy,". He gives off a really calm and composed vibe, making him seem like a pretty reliable person.[5] His speech is characterized by being very friendly and colloquial, using the "～っす/-ssu" copula in his sentence (in the Japanese release only). Fan translations usually adapt this pattern by using teenage slang in his lines.

Despite his appearance and manner of speech, he has cold, excellent insight and is both determined and brave. He even has downright frightening expressions whenever he gets very serious. While the other students descend into confusion and chaos when Monokuma and the Monokuma Kubs state their objective, he is capable of coldly interrogating them about their motives. He also shows a deep understanding of the situation and often talks and acts like he knows something the others don't know, saying profound-sounding and enigmatic sentences, which often make him sound suspicious or even eerie. He is shown to be very competent in the Killing Game scenario, understanding that to truly win the game, you must end it instead of outwitting other participants.

Due to surviving the previous Killing Game and participating in the current one, Rantaro gained the title of Ultimate Survivor.
