He has known her since childhood. They are constantly bickering, she's extremely annoying yet a familiar figure that is somewhat precious to him. Most of the time, he calls her Gremlin, but he strives to prove her that she's wrong and that he IS a good man (better than her). He might have had a crush on her when they were younger... But now he just wishes the unlucky chosen man good luck. Whenever he's with her, he can blow some steam off and even have some fun arguing with her. (though he inevitably ends up annoyed or angered...)
Kai is Celica's cousin, much like Yumi, his twin sister. And much like Yumi, she still loves her cousin deeply. She knows he would probably throw her to an executor if he were to catch her, but she still loves him. She's been watching his prowesses from afar and is very proud of the Guardian he has become. He is the only person who's opinion on herself matters aside from Yumi's. His anger and hate toward her do hurt but she learned to accept it.
Yumi is Celica's everything. Her cousin is her most precious person and she would gladly do anything for her. The soft bat is most likely what kept Celica sane through her toughest times, and now that she's found her again, she feels overwhelming shame whenever she kills someone. She wishes Yumi could be proud of her.
The two women are very close to each other, even though their family broke apart years ago, which Yumi is still really sad about, as she thinks Celica has never done any harm to anyone and their parents are the only responsibles in all this.
She may be a peaceful ashuri, she would do anything for her dear cousin.
They may be childhood friends but Yumi is a mystery to him, she felt so shy and outofworldly that he never dared bother her, though he always wanted her to join Kai, Ruby and himself on their adventures outside when they were kids. He really wants to know her more but has no idea how to do that. She's still very precious to him and he considers her a close friend.
Yumi knows the young man since childhood, but never talked that much with him, because she was very shy at that time (she still is actually) and never got the courage to go to him and learn to know him as he was already very close to Kai.
Lately, he became Ruby's boyfriend, and Yumi is relieved the milqilin has such a nice man by her side.
When his adoptive little brother told him he was getting married, Vulcain was shocked. When he met the wife-to-be, he was even more shocked, but also delighted. Yumi is such a soft, lovely lady that he instantly grew fond of her. He's very proud that Lux found himself someone as good as her. He looks forward to enjoy some more afternoon teas with her whenever she visits again.
Vincent is Plum's best friend. The both of them have known each other for a while now and they share everything with each other. She's one of the very few people that can make him smile and that he enjoys cuddling with. He would follow her to hell if she asked him to. He is happy to have a special place in her heart.
Leah is Yulan's everything. She means the world to him. He would (and did) do absolutely anything for her. He loves her so much it can be painful to be separated from her for a day. He desperately want a child with her and pray the goddess of Love every day and night.
Luann is Kai's servant and best friend since childhood. One of the few people able to handle the bat at all times, and takes great pride in it. Gives him blood whenever he wants out of habit (he even fills little jars ), and is used to his orders and swearwords. There are three people that Luann would give his life for, and Kai is one of them.
Kai is Lux's fiancée's twin brother. While their personalities were meant to clash, he restrains himself a lot when talking to him, because the bat is one of the few people that Lux does respect. He really wonders what the boy thinks about his mariage with her sister. But he's never asking that out loud. Ever. Despite being a lone wolf, he'd really be interested in teaming up with him to arrest some of the biggest slayers out there.
Tsubasa is Nova's dear pet. Literally, she entered his appartment by the window like a stray cat, and he took her in. She has managed to catch his interest, but she has no idea that means he's never letting go of her. Usually lacking patience, he restrains himself for his little kitty. He would skin alive anyone coming near her.
Adorable Italian girl. Dante met her and her sister completely by chance and overheard them talking in italian. He jumped on it and introduced himself in his mother tongue. immediately, they became friends. He feels an incredible warmth when he's close to her, since they come from the same country and she really feels like he's known her for ever. Plus, he adores her peppy personality. She's very fun to be around. She constantly asks about the ring on his finger, but he's yet to answer this one question...
Saul met her very recently at Honey's favorite shop and learnt she was Honey's best friend. Of course, his eye was immediately caught by her beauty, but he almost instantly knew he would get along with her. He thinks she's interesting, funny, and he looks forward to talk more to her. He's also honored that she seems to think highly of him.
They have known each other for a while. Roxie is the one who introduced Honey to Saul and his business, and so after they became friends they became co-workers as well. She loves cuddling and spending girl time with her ! Together
Ven was initially solely interested in Miel's body. He easily convinced her to sleep with him and enjoys her body a lot. However as time went by, he noticed she had caught his interest. He's very possessive and wishes her to only look at him, though he has yet to understand that these are symptoms of an early blooming love.
Yohan is a shy nerd studying musicology. Social disaster, he's akward with other people. He met Berry at a party and had sex with her while they were both drunk. Way to meet someone eh ? The next morning however, they noticed they had a lot in common and became actual friends (with benefits). Yohan is very supportive with Berry and her dreams. He thinks she has a lot of talent, and she's very beautiful. He secretely used her as inspiration for his novels before he started to talk to her, and he hopes she never find out about it because it's super embarassing and he does not want her to think he is a weirdo.
