Description
Pierre, whose full name is Pierre Bichelberger, is an idol associated with 315 Production and belongs to the mental-type category of performers. Before becoming an idol, he worked part-time at an amusement park as a mascot, wearing a full-body frog costume and handing out balloons to visitors. The costume concealed the fact that he is a golden-haired young man of striking appearance. In truth, Pierre is the prince of a foreign country, and his official profile lists his hometown as being beyond the sea. He came to Japan under the pretense of a visit to escape conflict over the royal succession.

Despite his royal background, Pierre is modest, warmhearted, and bright. He loves singing, dancing, and performing, and he views idol work as a way to bring joy to others. He frequently speaks of casting sparkling magic so that everyone can be happy, and he expresses a sincere desire to make the whole world smile. His Japanese is imperfect, which is part of why he originally found mascot work appealing, as the costume allowed him to make people happy without needing to speak. He struggles with kanji, sometimes asks for help reading scripts, and has a running gag of never being able to say the phrase for you are welcome correctly. He also carries a small frog doll named Kaeru, which mirrors the mascot design he used to wear, and he treats it as a close companion.

Pierre's central motivation is to use his own abilities to bring smiles to people. Having once hidden behind a costume, his growth as an idol involves learning to express himself more directly through his voice and performance. His cheerful persistence, genuine kindness, and earnest wish to spread happiness become defining qualities as he adjusts to life and work in Japan.

Within 315 Production, Pierre is a member of the unit Beit alongside Kyouji Takagaki and Minoru Watanabe, who were also former part-time workers. The three form a friendly and supportive group, and Pierre's innocent energy often helps lighten the mood. He works closely with the producer, whom he addresses with warmth and respect, and he is quietly accompanied by two bodyguards who follow him for his protection.

Pierre's notable abilities include singing and dancing, which he pursues with great enthusiasm. He is also a skilled martial artist, holding black belts in kendo, judo, and karate, making him more than capable of defending himself despite his gentle nature. In addition, he is very quick at changing into mascot costumes, a skill left over from his previous job. Ultimately, his most distinctive strength is his ability to uplift those around him through his sincerity, optimism, and hopeful outlook.
