Shinji and Aimi have had a rather mixed up relationship but thanks to them accepting who they truly are and becoming more comfortable with one another, they are now in a loving polyamorous relationship with Matsu Kusagare. Shinji and Aimi are playful with one another, sometimes saying things to each other that seems malicious in nature but in truth is kind of their love language, they would probably flip out on anyone who tried to join in.

Shinji and Aimi also have known each other since childhood both having lived in Sapporo around the same time, he became enamored with Aimi when she hit him with a bat after he was bullying her. She ended up being taken out of school but Shinji always kept close, concerned with her well-being. Secretly watching her up until she left Sapporo and wanting to stay close to her, he soon moved as well with his little brother, Hibiki Tatemono. Although he dated Hoshiko for a short time and she dated his father-- which obviously made things awkward for them at first.

Shinji has saved Aimi's life on many occasion and even revived her with his incubus powers, making her a succubus in the process. They're in love your honor.

Matsu and Aimi also have had a complicated relationship. Matsu being severely misunderstood at times by the peachette due to the fact that she had no idea he was autistic, sometimes taking innocent things he said as insults due to his blunt nature. They actually met earlier in life only once. Unknown to the both of them, they would meet again when the girl was 20 years old and still working under Kojiro.

Aimi fell in love with Matsu instantly but felt guilt for this due to her relationship and love of Shinji. Although it complicated the progression of their relationship and their desires for one another, Aimi and Matsu ended up entangled in each others spell for quite sometime before finally accepting their love and dating when she was 22; Matsu saving Aimi from herself and her mental issues. Unable to keep away from one another, they ended up solving the issue as eventually Shinji, Matsu and Aimi ended up all falling in love.

Matsu also is Aimi's past life lover being the reincarnation of the Egyptian God, Ra and Aimi having the spirit of Aphrodite; with her Egyptian counterpart being Hathor. Ra and Aphrodite were separated through lifetimes but have finally reunited with one another in their current lifetimes, which explains Matsu and Aimi's strong attachment to one another.

Sunni was Hoshiko's first official boyfriend. Unknown to either of the two, Sunni is a snake demon with terrible powers that he used on Hoshiko, abusing him in secret. Not being aware of this for years, Aimi assumed that their relationship simply ended due to irreconcilable differences.

Years later he returned into their lives through way of contacting Aimi with intention of gaining something from her. Already in a bad mental state at the time, Aimi ignored Sunni at first-- not finding him to be a threat. However, he was relentless in bothering her. Aimi soon found out about his torment on her best friend which deeply angered her as she had always wanted to protect Hoshiko.

However a bigger, mutual threat in the form of Kojiro Tatemono emerged which turned the tides of Sunni and Aimi's contentious relationship in the end. There was a deeper side to the snake demon whom was actually a practical puppet to Kojiro, a man he'd also had a long and difficult relationship with himself, by way of blackmail. Aimi softened to Sunni when he saved her family from impending danger and offered them refuge.

Slowly they'd both come to realize and try to deny their long growing feelings for one another but in the end, love wins and Sunni became another addition to their family and to Aimi's heart.

Kagami saved Aimi when she had run away from Toya, finding her at a bus stop in the middle of the rain and taking her home. They were alike in so many ways, instantly feeling a parent/child relationship almost akin to his and Hoshiko's relationship. Looking up to the man, Aimi finds him to be one of the most important people to her, wanting to help him with his own relationships and keep him happy.

Aimi and Kagami grew a bit distant thanks to their work lives and the fact that due to an accident, Hoshiko desired to leave their home, Aimi reluctantly following in tow, unsure of what happened to cause the drift between Kagami and Hoshiko. She still loves and respects Kagami, enjoying any time she gets to spend with him and playfully hiding behind him from Shinji.

Hibiki Tatemono happily came as a packaged deal with Shinji. When Aimi found out that Shinji was living in his car, she invited him to her home and they soon fought for custody for his younger brother and won the case. Since then Aimi and Hibiki have had a close relationship, treating each other instantly as family. Aimi adores Hibiki and his loving nickname for her and she would do absolutely anything she could to protect him.

She often times bothers him-- although he doesn't ever seem to mind. Much like his older brother, Hibiki is also an demon/incubus.

Another packaged deal, Kiku is Matsu's biological son with his ex-wife. Kiku is a very complicated kid, another learning curve. Akin to his father, he is also on the spectrum and seemingly avoidant behavior. However, Aimi clings to him in hopes that one day he'll like her. ( Which he's beginning to :D ) Aimi is also very protective of Kiku as she is with her entire family, giving him solitude when he needs a break from Miyu.

Kiku makes Aimi happy in ways she can't explain. Kiku is also the reincarnation of Aphrodite's son, Eros. Although thus far, this has yet to show itself, possibly because Kiku is still young.

Several years after Aimi's departure from her home in the Sakurano estate, her parents for some reason ended up having yet another child whom was also subjected to abuse of her own at the hands of her mother. Their mother's mental health severely having deteriorated, she went as far as to name their child Aimi once again, wanting to regain some semblance of her daughter.

Matsu having accompanied Aimi when she was visiting the estate in a state of mental disorder, he ended up spotting the young child and made a split decision to take her home. Technically kidnapping the young girl, Aimi is grateful to have her freed, not having had known she even had this little sister. Choosing her own new name to gain her own identity, she ended up as Miyu Sakurano and instantly opened up to everyone in their apartment complex.

Aimi wants to give the girl a normal life and keep her from truly remembering the worst of her abuse. They became incredibly close--seeing as they're some of the only girls and also sisters.

Aura was saved from a terrible situation by Matsu who kept her safe and eventually took her in to live with. Due to Aimi and Matsu's accidental treatment of the situation, around this time they broke up from when they were first together. However, as they got back together, Aura being one of the only girls around her, Aimi often watches her curiously; although because she's had limited interaction with those of the same sex, she's still curious about her.

Aimi wants to be closer to Aura, considering she lives with them and she has a strong connection to Matsu-- However, they're still working on it.

Autumn is currently Aimi's employer, being a fashion designer; she hired Aimi as a model for some of her clothing lines. Aimi deeply admires Autumn, clinging to her whenever she's around and genuinely caring for her there are times when Aimi would just enter her place of work just to spend time with the gorgeous seasonal Goddess.

Autumn has taken a pivotal role in Aimi and the rest of her family's lives whenever they need-- even going as far as to use her Goddess powers to revive some of them. Aimi often goes to Autumn for advice, finding Autumn to be highly intelligent and a fun conversationalist.

Kojiro, father of Shinji Tatemono was the employer of Aimi at FATAL TASTE and due to her need for validation and love, she ended up dating him for quite a while. Kojiro, never having been a good person was a demon, dealing in unsavory practices due to his lack of morality. Aimi often went to Kojiro whenever Hoshiko was busy, needing to fill that void since she cannot be alone. Aimi was also abused at times by the man, especially mentally. Aimi, not having experience with relationships, kept this from everyone. Although it was obvious if you knew Kojiro's nature.

Having an on and off relationship, their "relationship "romance" eventually faded away without much thought. However, Kojiro being the narcissist has seemingly decided to complicate Aimi and her family's lives.
