Haruka Fujibayashi/Relationships

Erwin von Arnim
Erwin is immediately taken aback by Haruka's natural beauty, displaying his severe weakness for Japanese features that also caused him to fall for Karla von Browig prior. Since they are both acting as bodyguards and are both sword users, he uses those facts as an opportunity to get close to her, however she is unaware that he has any potential feelings for her.

Erwin begins taking swordsmanship lessons from her, finding that he has more talent for Japanese-style samurai swordsmanship than for traditional style. He wishes to ask for Haruka to be his wife, but her brother Takeomi Fujibayashi attempts to intervene. After Wendelin von Benno Baumeister defeats Takeomi in a duel, he explains to her that Erwin wishes to marry her and she accepts the proposal.

Following their engagement, they spend a significant amount of their free time getting close, and their relationship blossoms. She continues to instruct him in samurai swordsmanship. The two stay with each other nearly all the time, fighting side-by--side.

Takeomi Fujibayashi

He repeatedly tries to get in the way of Haruka's relationship with Erwin, struggling with it even after the two are engaged.
