Saionji Amane

Kazuya's childhood friend. She may seem scatterbrained, but she's actually quite good at everything except cooking and sports. Her grandfather is a brilliant scientist, and Amane carries some of his stranger inventions with her wherever she goes. More than anything, she wants to help Kazuya, who got caught up in the battle against the Evolutions trying to protect her.
