SPOILER WARNING (Highlight to read) 

At the end of Part 1, Hazumi is taken into forced labour and seperated from Nacht as he had lost the tournament. While Nacht had received the money to bail her out from Remedia, he was knocked out and the money was stolen.

Soon after in Part 2, Toushin Bolt Allen reunites Hazumi with Nacht, but her emotions had been sealed away as she was caught in the crossfire when Nacht father staged a coup to usurp power in the Toushin district. Nacht attempts to cure this by bringing her a shellfish, which she had once used to enchant items, but while she instinctively enchants his weapons, it is to no avail.

Finally in Part 3, it is revealed that Bolt Allen's story was a lie, and he was part of the evil conspiracy all along. In truth, Hazumi is being mind-controlled by a magic stone implanted onto her. However, with the "help" of Fiori Mifiori, Nacht manages to remove her mind control. They finally confess their love for each other and Hazumi also resolves her conflicted tension with Remedia. She then assists Nacht in the final counterattack to escape from the district.

In the end, it is also revealed that Hazumi's father was not crippled in an accident, but rather the mine collapse was planned by Remedia's father. Remedia is also revealed to be her cousin and Hazumi is last seen in the ending embracing a reincarnated Remedia.
