Pierre L'Supérieure, known as Eita Kyuando in the Japanese version, is a character in the Yu-Gi-Oh! Arc-V anime. He is a student at Clarity Prep School who is arranged to duel Yuya Sakaki by Nico Smiley, and this arranged match is the main context in which he appears in the story.

In terms of personality, Pierre is portrayed as an arrogant duelist. He is known for always wanting to get everything right in quizzes, and this trait strongly shapes his behavior and his public reputation. His attitude reflects a belief in his own knowledge and precision, and he carries that confidence into his interactions as a duelist.

His motivation is closely tied to being correct and proving his superiority, and he treats the arranged duel as a chance to demonstrate that his way of thinking is the right one. His approach is therefore rooted in his intellectual self-assurance and his desire to be seen as flawless.

His key relationships are with Yuya Sakaki, who serves as his opponent in the arranged match, and with Nico Smiley, who sets up the duel. His affiliation with Clarity Prep School provides the background for his character and connects his quiz-focused identity to the academic setting he represents.

The character's notable ability is his expertise with quizzes and the knowledge-based confidence he brings to dueling, which sets him apart from other challengers Yuya faces. Because he appears in a limited capacity within the series, there is little room for significant character development, and he remains defined by his role as a proud, academically minded student duelist.
