The story is setup so that bell ends up with ais.

I mean liaris freese exists for bell because of her so....

While it is not confirmed, it seems that Bell will end up with Ais. However if it goes that way, Oomori should give the rest of his harem a happy ending (and not pushed to the side like other harem animes). Others do say that they wouldn't mind a soft harem ending (maybe 2-3 girls), I mean it's an eh for me, I don't really mind who he ends up with.

Bell will most likely end up with Ais in the end but what the other girls in his life will have to say about this is something that I am curious about.

I just hope that Tiona and Bell do not ever get into a conflict and Bell defeats her because I am starting to get the impression that Bell might be her type. If she is anything like her sister then she might become extremely possessive.

I mean Finn has denied Tione's advances but she just will not get the hint.

Although, a fight between her and Ais over who gets Bell would be entertaining.

That would be entertaining, though what about Ryu? Wonder what she'd feel like after knowing that Bell is after someone else, her friends did say to not let him go, got to see what happens there.

While it is clear that Bell and Ais will have a relationship in some capacity, the harem route is still very much alive as the author refuses to stop making more and more girls fall in love with Bell, and continues to develop their feelings toward him. The only real endgames for the romance subplot going by the plot and narrative are Ais x Bell and Bell x Harem. An open ending is just the author chickening out and not finishing the story and doesn't count.

For me, I'd prefer a ending like this

Ais is facing the OEBD, and due to her hatred and drive for revenge above all else, she let's many people in her familia and many other's in other familia's die simply because she isn't willing to wait for revenge, and not only does she die, she drag's dozen's if not hundred's of people to death with her and get many more injured as Bell saves the day with his powers and determination, and end's up making the harem as he lost his love of Ais learning that you can't fall in love with the first thing you see

That was pretty depressing ngl

That's the point, it's to teach Bell that his first love should not be on look's alone and someone who doesn't know him to well, it should be someone who he knows and is close to naturally

Ais and Bell's relationship is not only unnatural and only existed because Ais wanted to learn how he was growing stronger and faster, but it was also fragile as Ais seemed to not care about Bell enough to listen to him about the Xeno's until Wiene literally ripped part's of her body out, her feeling's for Bell are no more than her wanting to learn his secret to getting stronger faster, and if she knew, she would have likely never gone any farther than apologizing and then vanishing that instant without a second though

This is how I see it, and as an example of what could have been a healthy relationship in my opinion and who I wish Bell would get with is Haruhime, my reason why is because she didn't use Bell in any way and has been honest with him and only lied to him for his own good, and once she was saved from Ishtar, she did everything in and beyond her power to help Bell and is loyal to Bell to a fault

some can say Lily is good, but she stole and lied to Bell at first, so I am holding that against her a bit

Mikoto love's Takemikazuchi so she's a no go

Enia is not given enough screen time for me to make a proper or accurate enough judgment yet compared to the others as of yet

Ryuu is complicated and is likely suppressing her feeling's for Syu/Freya so she isn't that good in that sense of holding her true self back

Hestia is a bad match since she is more obsessed with Bell since she wants him even if he's unhappy in my eyes, and Bell sees her as a mother figure above all else, and will not violate that relationship, so for me, I respect Bell for rejecting a goddesses love not our of spite because they love someone else, but rather, respect of them as family

Freya is much worse as she would hurt Bell in a near or completely fatal way for her own happiness above all else as well as Bell only meeting her one time and that wasn't much as Bell himself isn't even what Freya is in love with in the first place

Lefiya would be a good contender in all honesty as both are alike in many ways in all honesty and rival's Haruhime in that sense in my opinion if not for her petty jealousy of Bell for something beyond his power and not his fault

And I can go on, but you get what I'm saying, right, Ais is a bad match because she's to focused on her own petty goal of revenge, I'm not saying she doesn't have a right to be mad, but she need's to move on and live her life, or she let the OEBD win before she even faces it
