This page outlines Hibari's relationship with characters in the Senran Kagura 3DS series.
Hibari and Asuka seems to have a stable relationship. Besides their little interactions with one another during the Hanzo story mode of Burst, they haven't interacted much. However, they see one another as friends and comrades that are willing to help out each other.
Hibari and Ikaruga seems to have a stable relationship. They haven't interacted with one another individually, but Hibari does see Ikaruga as her senior and older sister along with Katsuragi.
Hibari and Katsuragi seems to have a stable relationship. They haven't interacted with one another individually, but Hibari does see Katsuragi as her senior and older sister along with Ikaruga. In some cases, Hibari likes getting herself involved with Katsuragi's shenanigans, which causes Yagyū to step in and threaten to kill Katsuragi sometimes.
Hibari's relationship with Yagyū is a tight one. She sees Yagyū as a very close friend. Yagyū loves taking care of Hibari because Hibari reminds Yagyū of her deceased younger sister, Nozomi. On most occasions, Hibari appreciate Yagyū's love, but there are some cases where she gets annoyed with how Yagyū babies her, especially if it makes her feel weak and helpless. These instances are shown during the events of the Hanzo story mode of Burst and Deep Crimson.
Homura Crimson Squad
Hibari's relationship with Haruka is just as tight as her relationship with Yagyū. Throughout the Hanzo Story mode of Burst, the interaction between Hibari and Haruka revolves with Hibari trying to beat Haruka to prove that she's not weak and helpess while Haruka messes with Hibari like one of her dolls. When Hibari transferred to Hebijo Clandestine Girls' Academy to retrieve Hanzō National Academy's Super Secret Ninja Scroll, she realizes that Haruka and the rest of the Hebijo elite group aren't bad people. From that point on, Hibari tries her best to befriend Haruka. After their last fight, Hibari was able to befriend Haruka.
Their new bond expands further during the events of Deep Crimson.
