Rantaro Amami

When he was first introduced, Rantaro seemed like a mysterious individual. Later it could be seen that he is a carefree and relaxed person. 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.[7] 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.

Rantaros favourite sex activity is to have his armpits fucked or to lick someone's armpits. He also enjoys receiving head and using ice to create a sensation.
