Pierre Bichelberger is a young foreign prince who worked as a mascot in an amusement park handing out balloons. It was a job well suited to him, as mascots aren't required to speak (Pierre's Japanese is less than perfect) but are still able to make people happy. He loves to make people smile, and decided a career change to an idol was a natural next step with Minori's help. The two of them afterwards recruited Kyoji to join the unit, and the trio of Beit was born.
