I doubt the Author would have things play out as such, though I do think it could be revealed Lefyia has a similar (Repressed) Admiration for him similar to how she views Aiz.

Honestly, this scenario seems suspicious to me. Normally, Lefiya has always been in the middle of the fray alongside the first-class adventurers; following that pattern, she should have fallen to the 61st floor with all of them.

However, Omori left her behind to represent the Loki family on the rescue team, which will most likely result in her spending a lot of time with Bell, going through ordeals together. In fact, the final image of SO15 shows her staring at Bell as if she were pinning her hopes on him.

So, this narrative setup feels premeditated; that is, Omori is deliberately pairing Bell with Lefiya on a grand adventure, most likely so that "something" might develop between them. At least that's how I see it.

Lefiya has matured in her own way through volume 13 of SO. just like bell had, though both of them also regressed somewhat i feel in the later volumes. I wonder if lefiya will be named finally in Danmachi volume 21. anyways, this will be there adventure to save Ais. thus having to set aside their differences. well, the issue with the idea of a romance is that even in volume 18, he did not bother naming this elf. so suddenly saying her having so many interactions with bell just feels weird.

I did hear that Bell groped Lefiya is this true because the act is similar to what Issei in dxd specializes.

Both Lefiya and Bell have matured, but you need to manage your expectations. Omori won’t allow them to mature completely, because that would ruin all the “comedic” scenes he tends to use. For example, if Bell fully matured, he wouldn’t let himself be constantly harassed by his usual annoying pursuers like Hestia and Lili, and he would clarify the situation once and for all—something Omori clearly doesn’t want to do. Therefore, to maintain his “humorous” style, it’s essential that Bell remains immature—weak-willed—so he continues to let himself be harassed.

As for whether Lefiya will finally be mentioned in the main series, I already take it as a given; otherwise, Omori wouldn’t have shown that image of her looking at him with hope. Since this will be such an important mission for both of them, I doubt their interactions will be the usual ones—Lefiya bothering Bell out of jealousy. Instead, we’ll see their more mature and professional sides, which will likely change the nature of their relationship.

Honestly, I don’t find it strange at all that a new adventure would be created to make them interact a lot and very intensely. That’s basically how this series has always worked. That’s why we talk about the “Ryuu arc” or the “Freya arc,” referring to the character Bell interacted with the most during each event. Now, it’s simply Lefiya’s turn.

Of course, there’s a fairly speculative element to all this, but I suggest it because it seems very odd to me that Lefiya didn’t fall to floor 61 along with the others, especially since Omori had been raising her status at a pace similar to Bell’s, and that would have been a perfect opportunity to continue with that. So, the fact that she stayed behind and now seems to be placing her hopes in Bell feels like a deliberate decision, aimed at bringing the two of them together. Strictly speaking, Lefiya wasn’t necessary to negotiate with Bell—Omori could have sent Raul to talk to him, and once Raul explained the danger Ais is in, Bell would have agreed to cooperate immediately.

The issue now with Lefiya is jealousy because her so called rival has long eclipsed the Elf.

She saw him battling Ottar even with her magic power the girl falls to Bell.

I do want eventually for his rapid growth skill to be revealed although this will crush Lefiya.

Lefiya will have to accept and bow down in respect to Bell that he is superior to her, and wait until she learns of Realis phrase his growth kill.

She will say how in the hell I can compete with this and is so unfair.

The jealousy aspect will show its ugly head nothing against Lefiya the girl has been left in the dust.

She will become a exemplary mage in my opinion but Bell right now is OP .

Bell as a comparison is like Sung Jinwoo of Solo leveling to Lefiya using a analogy the boy is overpowered.

The answer to this question is a affirmative no on all accounts there isn’t a chance in hell.

I don’t see a chance in hell of Lefiya falling for him and Bell is obsessed with Ais in the same level to Freya.
