Reira Akaba

赤馬 零羅
The younger sister of Akaba Reiji, dueling in the Junior class of the Maiami Tournament. She is very timid and shy, always carrying a patchwork teddy bear with her, even going as far as hiding behind its face as the crowd cheered. For most of the series, she is mistaken and referred as a boy due to her masculine clothing until the final Duel against Zarc.
