Kenichi Mochizuki

Balsa the spearwoman is a wandering warrior, who takes on the task of saving lives, in atonement for a past sin. On her journey, she happens to save a prince, and is tasked with becoming his bodyguard. And he is going to need one, for his own father, the emperor, wants him dead. Throughout the story, Balsa's past will come to light and they will uncover mysteries about Chagum's condition while developing a family-like relationship with each other and others.

Yuichi hasn’t seen his cousin Nayuki in years. Now that he’s back, all knowledge of ever visiting has vanished. He tries to adjust to the vaguely familiar surroundings, but the gaps in his memory haunt him as time grows short. The pieces of the puzzle have appeared – an eerily silent beauty with blazing tresses, the mysterious girl with the winged backpack, and the sword-wielding demon slayer – but it’s up to Yuichi to discover how they fit together.
