Cross Fight B-Daman: Legendary Phoenix

Enzi Hikigane may seem like a rough-and-tumble protagonist but he is an exceptionally-skilled B-Der that uses his elusive custom-made Spike=Phoenix to earn a livelihood in the bustling city. One day, he meets Hajime Tamauchi, an average joe whose interest in B-Daman started after watching Enzi's B-damanccentric tricks of the trade. The series follows the daily life of Enzi and Hajime as they bid their way to be the best B-Ders and also to fend off those who are trying to capture the elusive Phoenix.
