Yes, Haruna-chan has relationships
Ayumu Aikawa - Zombie & Masou Shoujo (@ayumuaikawa)

Haruna is responsible for Ayumu being a masou shoujo because he supposedly ‘stole’ her powers and now fights megalos in her place. Their relationship was really rocky at first, in fact they fought non-stop since the night they met in the graveyard. Haruna was always calling him absurd names such as a “Stupid Pervorse” or a “Sexual Harassment Devil”. But in spite of all that, Haruna had fallen in love with the zombie; developing a sort of tsundere attitude to hide her true feelings. As time passed their heated arguments evolved into a sweet passion towards one another, and Haruna confessed. Ayumu since then has realized his true feelings for her and confessed as well. The masou shoujo and the zombie are now happily boyfriend and girlfriend, sealing it with a kiss.
Ayumu really means a lot to her, although she is usually reluctant to admit it out loud. The thing is Haruna never cared to remember anything unless she deemed it to be interesting. Surprisingly she remembers and calls him by his name while almost everyone else she knows has been given a nickname. Ayumu is someone special to Haruna, and she bothers to remember because she loves him.
Eucliwood Hellscythe - Necromancer (@euthenecromancer)

Haruna didn’t exactly care for Eu at first, in fact they practically ignored each others presence while living under the same roof. She calls her Necromancer and they eventually become friends. Although Haruna sees it more as a sibling bond after Eu gets sick one day and now refers to herself as her Onee-chan. When the two switch places for a day Haruna gains a new respect for the Necromancer because she was able to experience her pain and suffering, admitting that it really is hard to conceal your emotions. For the most part Haruna and Eu seem to get along just fine but sometimes she can get pretty jealous of her seeing as she was Ayumu’s initial interest. But when alone together they really do act like best friends.
Seraphim - Vampire Ninja

Often calling her Leafy or Leaf Girl because of her leaf based attacks, Haruna wasn’t too excited when Sera barged into the house uninvited and unknown. But in the latter Haruna sees her as like a big sister. One time she had to kiss Haruna in order to suck blood out of her to continue on living, but they aren’t considered married because of it. She is the complete opposite of Haruna when it comes to cooking so she tries to teach Sera how to get better because the dishes she would end up making were deadly and disgusting. The irony is that she works at a restaurant although it’s because her clan operates it and uses it as a hideout. Haruna works there part time as a maid.
Mael Strom/Yuki Yoshida - Vampire Ninja & “Wife”

Because of Haruna Yuki is considered Ayumu’s wife under vampire ninja law; she pushed him into her and accidentally kissed Yuki. Ever since then she’s had a complicated relationship with her, and deep down Haruna regrets what she did that made the marriage possible. It’s not that she doesn’t like her, but becomes extremely jealous of her; to the point where she wanted Ayumu to kiss her once so they can be pronounced married too even though Haruna isn’t a vampire ninja. She occasionally becomes delusional whenever she sees the two together causing her to fluster and flail. Haruna nickname’s her Yukinori combining her civilian name with the name that only Ayumu is allowed to call her, Tomonori.
Ariel/Dai-sensei - Masou Shoujo & Teacher

Ariel is usually referred to as Dai-sensei and is Haruna’s teacher back at her school where masou shoujos train, Matelis. She is super powerful despite her physical appearance and her innocent voice. She sent Haruna to Kyoto to buy tofu but she ended up in Tokyo where she had her fateful encounter with Ayumu. Haruna looks up to Ariel almost like a motherly-figure. She’s the one other person who she calls by name indicating Dai-sensei is an important person in Haruna’s life.
Kyoko - Masou Shoujo & Mortal Enemy

Kyoko is a masou shoujo just like Haruna and was once Dai-sensei’s pupil before betraying her. Haruna couldn’t care less about Kyoko until she started attacking her and her friends with evil intent. Hence Haruna had developed a rivalry with her and a bit of hatred, although there are still times where she shows no concern for her whatsoever. The thing that really gets on Haruna’s nerves is that Kyoko constantly tries to flirt and manipulate Ayumu, using her abnormal sized breasts as bait.
Madoka Kaname - Good Friend (@madoka-dokidoki)

Haruna came to grow fond of Madoka the more they interacted with each other and expressed concern for her when she was sprung on an energy drink called, Morning Rescue. The reason she likes Madoka so much is because she senses something more in her other than just being a sweet pink-haired school girl; believing that she is secretly a very powerful magical girl. Plus she enjoys the conversations they have together and she never fails to make her chuckle. Her suspicion about Madoka being a magical girl eventually came to light, proving Haruna’s genius instincts to be right again. Haruna nicknames her Madokidoki.
Minato Arisato - Frenemy (@minatovstheworld)

When Haruna first met Minato she immediately jumped to the conclusion that he was a creepy stalker. She began to think this statement was true when he refused to leave her alone and then used mysterious blue cards to cast some weird spell on her, eventually finding out it was to rejuvenate her masou shoujo powers. Nicknamed the Mysterious Blue-Haired Guy Haruna came to terms with him when he compared her to a Pikachu which made her really happy, but she still keeps on her toes whenever he’s around just in case. He recently became Haruna’s “Onii-chan” and does a pretty good job at looking after and supporting her.
Kazumi - Magical Buddy (@dead-or-rice)

Witnessing Kazumi’s energetic attitude first hand instantly made Haruna become interested in her and want to remember her name. Kazumi was always praising her and saying that she loved Haruna’s wide smile while Haruna really admired her fuschia tinted eyes. In the past Haruna said that masou shoujos are beyond superior to mahou shoujos but after meeting Kazumi she came to realization that she’s not so bad herself.
Rita Mordio - Rival & Twinsie (@hotheadedgenius)

When Haruna had her encounter with Rita she proclaimed herself as a genius, which did not amuse her in any sense because she was the only one that ever claimed that title. The two hit it off immediately, creating a friendly rivalry. Haruna seeing her as someone that’s actually worth challenging. They’ve been quarreling over who’s better since day one, even to the point where they brought their respective boyfriends into the arguments. Rita resembles Haruna greatly not only in ego and arrogant personality, but in appearance. Hence why they’re called twinsies. Even though they constantly tease and taunt each other about everything, deep down the two probably have taken a huge liking towards one another. Haruna nicknames her Goggle-girl.
Sasuke Uchiha - Ninja & Friend (@uchiha—avenger)

The only thing Haruna finds interesting about Sasuke is that he’s a ninja and has “magical” eyes. So it was only right to nickname him Magical-eyed ninja, though she never really uses it. The correct term for Sasuke’s special pupils are called his, “Sharingan”. Originally thinking that the only thing it does is change the color of his irises he convinced her that they’re abilities are far more powerful. She once demanded him to teach her how to get them to only learn that it was a hereditary thing. Haruna and Sasuke don’t talk much but because Mun has taken a liking to him Haruna is pretty much forced to associate herself with him, sometimes trying to lend a helping hand when he is in distress. Although she isn’t very good at comforting others, Sasuke seems to appreciate that she cares enough to at least try.
Azure Ishiwatari - Demon & Acquaintance (@azurerp)

Upon meeting him in a local grocery store after both grabbed the same egg carton Haruna had originally thought he looked kind of cute. He insisted on going over to her home and cooking for her after confessing he had nothing else to do. Apart from finding him a bit attractive she really didn’t care for him all that much even after he had already entered her home. It was only when he indirectly told her he was a demon that Haruna had become fully alerted of his presence since all her life she was trained to kill such things. Ever since then she’s been joking about killing him someday but he’s proven to her that he’s a very kind being despite his status. Although that doesn’t stop her from teasing.
