The reason I'm asking is the rare skill that Bell has increases his stats as long as he looks up/wants to reach Ais. But at the pace that Bell is levelling up (level 4 in 4 months ?), I wouldn't be too surprised if Bell reaches level 6 in an year from the start of the story. So, he has 8 months to level up twice. Quite possible given that he has almost single-handedly fought Juggernaught & we don't how the dungeon will expose its fangs on level 37 (he's alone with Ryu). So, all in all it's quite possible for him to reach level 6 in 8 months from now. If you ask, where I'm going with this with all this timeline ? I think Ais levelled up to level 6 almost around the time Bell reached level 2, so unless Omori pulls 1 out of the hat she won't be levelling to 7 anytime soon.
