Gigant Big-Shot Tsukasa

The anime follows Tsukasa, whose dream is to become the best at Gigant Shooter (battles in a game similar to pog) in the world. The menko card his father left for him called King Menger is his partner. Tsukasa's fellow gamers are the cute but tsundere Koide Miruko, the spectacled bully Numata Manabu, and the realist and sharp-tongued Doumoto Ataru.
