It makes the most sense thematically for Bell to be the Strongest Adventurer, as well as making sense logically and fitting in with certain things said in the early books. Of course, to do that, he'd have to reach at least level 9 or 10. Which is highly unlikely to say the least, given that Oomori has been slowing down the rate of his level ups when if anything they need to be faster. And of course meaning the amount of plot armor for the final fight will be unlike anything seen before.

I honestly don't know where Bell's going to end up. I think level 7 is a safe bet, but anything past that is iffy.

Based on the timeframe he is leveling up and remaining time lv6 and halfway to 7.

Level six is not enough to beat OEBD he will need a ton of help basically every Familia and a Divine miracle.

Loki helping will be not enough this monster decimated the strongest Familia in record along with Hera.

Bell will probably hit level 7 (its stretching it though) and that will be it. Have you guys ever heard of power of love or power of friendship? That's all that's going to be needed to win the big fight in a shonen type story.

Abigail is probably going to end up being right and it will hurt the final quality of the story so much. Why didn't the Zeus and Hera Familias just care about their friends and loved ones?! If only Alfia had loved her sister, she could've pummeled the thing! Oh wait

Power of love is this a Care Bears episode to me realistically it would be everyone giving their power to Bell to deliver a devastating attack to oebd.

This is similar to Dragon Ball with the move of Goku that gathers all the energy from everyone.

I used to think Bell would be Level 7 by the time of the battle with the OEBD and its defeat would grant him a final level up, making him be at the highest level in history. This is a shonen afterall, so he is obviously set to be recognized as the strongest by the end.

Then I believed it would be waaay higher, but discarded it with seeing how slow Oomori is making him progress. So personally I think its gonna be like I originally thought, so that he can be officially among the strongest. Since there would only be, officially, two other people that were a match for him at most.

@Rigel31415 The highest we know of in history was Level 9. Ottar is going to be Level 8 within the next few books, almost certainly. Bell would need to be Level 9 to be the strongest living, Level 10 to be the strongest of all time. It's almost certain neither is going to happen.

Bell will reach level ten but not on this story his realis phrase will make him stronger than Ottar.

Bell can’t reach this height due to the author limiting the story and not wanting him to get to age 15.

The age reason is extremely dumb in my opinion trying to make the lead not growing up.

Honestly a time limit of 2 year will have been nice or at least a year and half
