Wakaba Nogi

A second-year middle school student and one of the Heroes of the first Hero Team and the ancestor of Sonoko. Wakaba is a serious, strong-willed girl that believes in rewarding favors. She seeks revenge on the Vertexes and is willing to take risks to get it. She is a natural, charismatic leader who is wildly popular with the general public. However, she is also a kindhearted girl who is dismayed that her serious exterior sometimes scares people off, and she has a hidden soft side which enjoys being spoiled by Hinata.

As a Hero, Wakaba fights using a sword named Ikutachi. It can cut through Vertexes with ease, even if the user is not transformed. Ikutachi is one-handed, meaning she has no need to hold onto it with both hands.
