1. Ozzy was literally willing to grant Elise’s wish without the gifts, so she wouldn’t have needed to gather them and lose her gf if it weren’t for Walpurga telling her she needed to gather said gifts

2. While Ozzy does have scenarios where he kills Elise, it was never his first intention to do so, meanwhile Walpurga had that intention, and wanted to inhabit her body, while I understand why, it’s still extremely messed up

3. Ozzy gave Elise the potential girlfriend of Rozenmarine, who in all intensive purposes is the perfect sacrifice which is sorta nice in a messed up way, and even if she isn’t sacrificed she’s still a supportive girlfriend who understands her pain, offers comfort, company, and good soup

Random headcanon: Ozzy just rubs it in Walpurga’s face that he’s somehow the better parent between the two

Also Elise is so obviously Ozzy’s favorite child, I’m sorry Enjel but it’s true

Both, Walpurga and Him have been watching closely, both have their own reasons to be interested on Elise but at the end was Walpurga who manage to claim her before she could met him, taking what its hers and finally finding a way to fulfill her wish, to become a woman

Walpurga has being a wanting to be a woman and have a baby, and now that she can finally do it she was just enjoying her new life without worring about the time, enjoying the simply fact of being alive, and not just that, but also enjoying the slow and beautiful process of falling in love with you, Elise's good company. Now that she stoped Elise from meeting him you are safe too, and thanks to following Elise she does know a bit of you but now she can finally meet you in person, understanding Elise's feelings and now being able to personallly be with you (taking advantage of the fact that her feelings are indirectly corresponded)

However, not everything will be easy for Walpurga, Ozzy was quite interested on Elise too, and even if she didn't mange to even reach the table he is quite mad about the fact that now she's gone, if Walpurga is going to play this way then he can do it too, taking away her new favorite person to make it up for taking away Elise from him

Even if Ozzy and Walpurga have worked together in the past he is quite mischievous so at first this was more like a simple game for him, wanting to mess with her by sending his servants to advice Walpurga to be carefuly or else he will take her beloved. At first was just a simple game, but by being watching over Walpurga he end up indirectly meeting you too, being able too see how interesting you truly are, maybe even as interesting as Elise was! now Ozzy really wants to reach you to be able to truly meet you!

It take a lot of work from his part to be able to meet you without her being present, but when he did he acted kind and playful, taking your hand in his and saying that he was an old friend of your beloved. Ozzy's love for you grow slowly, between the little interactions he had with you to what he saw while talking you without that witch, Ozzy himself was surprised by his own feeling but not disapointed, he found them quite funny and will follow them without shame

Ozzy doesn't exactly hate Walpurga, but since she wasn't going to let you stay close to him then he decided to attract you, if she wasn't going to share you then he will just take you to himself with the excuse of being able to make any wish you want come true. It leaded to a heavy fight between both, Walpurga angrily begging you to dont listen to that demon while Ozzy was trying sweeten you ear with the promise of all you could ever wish for

Walpurga would be the one confronting Ozzy about this, she was finally living her dream and she wasn't going to lose it for an idiot messing with whats hers, but Ozzy didn't care much about her anger and propoused to share you with him, letting you come here and visit him and his servants whenever he misses you or else he will have to put an end at this and lull you to be his new beloved Golden Maiden

At the end, Walpurga didn't have another option than accept to share you, but she will never be happy with this deal. They try to make it work for the sake of your safety and their happiness, Walpurga takes advantage of her new life to stick with you all day, keeping you as close as posible (almost rubbing it in his face how you two can live a happy life together like any other human while he can't, something that he doesn't care much about but at the same time annoys him), while every night you are always dragged to his realm to visit him, have little adventures together or share a meal at his table, sometimes he even choose to pay you and Walpurga a visit in your house instead of dragging you (mainly to mess with Walpurga, being all affectionate and clingy with you in front of her)

Despite Ozzy being mischievous he nor Walpurga mean to harm you, both know how fragile humans can be and if they do something wrong they could lose you by their own hands and non of them want that, so you don't really have to worry about your safety, however you are pretty much trapped in their little game, you don't have voice nor vote on this, they may love you but they won't do what you want, your life is now in their hands and even when you have some freedom is not enough to keep your life as what it was

Even so, it may not be too bad, Ozzy has his way to your heart with his words, he knows exactly what to say to win you over, while Walpurga couldn't be happier to have you in her life and thats obvious in her affectionate actions and efforts to make you happy too
