Position: Cheerleading Captain (self-appointed)

Suzuna is a cute blue-haired girl who's always wearing rollerblades.
She came to the United States to look for her brother and hitched a ride with one of the bikers of a bike gang.

Later, after her brother accepts Sena's offer to join the Devil Bats, Suzuna follows the team back to Japan. She then becomes a cheerleader for the Devil Bats.

In the anime, Suzuna was introduced earlier in the timeline as a part-time reporter, working for the magazine American Football Monthly to discover Eyeshield 21's identity. Her reason was to find her long-lost brother, whom she suspected was Eyeshield 21. Realizing that Eyeshield 21 was too short however, she then leaves for America due to a tip from Hiruma.
