Junko is introduced in episode one of the anime. She's very skilled with a short blade and wooden sword, both of which she carries or summons. She also has a tsundere nature, often becoming embarrassed and misunderstanding situations because of that. She comes from a Suharaist family that protects the Empire and is very strict about upholding the values that were taught to her.

She wants to marry Sai Akuto and even temporarily removed herself from her family to aid Sai when he was in trouble, trying to destroy the Gods and save Keena. As Sai was about to leave on Peterhausen, he told her that when he gets back he will take good care of her.
