Unleash The B-Daman Power

The story takes place in year 20XX - in the town of East City, where the newest toy B-Daman is becoming more and more popular. Riki Ryugasaki is a quiet schoolboy who wants to be an adventurer when he grows up and his favourite word is mystery'. Riki has a lively personality, but can be a bit vague at times - he marches to the beat of his own drum. One day Riki is taken to his first B-Daman event by his friend and classmate, Sumi Inaba. Although he doesn't participate as a player, Riki's natural curiosity sparks an interest towards B-Daman and when Riki hears an urban legend about a secret B-Daman tournament - a tournament that only a very selected group of players are allowed to participate - he realises that there is something very mysterious and exciting about B-Daman. Riki is sure that the story is nonsense, but just then a mysterious, unidentifiable voice calls out to him: Boy, there are still many things in this world that you know nothing about'. Along with the voice, a boy named Samuru Shigami holding a White Dragon Type B-Daman appears. Riki senses something overwhelming in that cool and mysterious atmosphere. Samuru walks away and disappears. What is the mystery behind the B-Daman?
