confusing..looks like rachel used baam to open the gate and get to the testing floor, but then got rejected from climbing the tower. If so, who is the regular/irregular? Hopefully, next chapter will explain things. Either Rachel used baam all along or she is jealous/or misunderstood the reason why baam is able to climb the tower (she couldn't hear the conversation between the admin and baam)

In a way, Rachel used Baam to open the door.. But not literally. It's more like the door was opened for Baam, but Rachel accidentally fell in it too. [Rachel was closer to the floor door to the Tower than Baam, so she was accidentally sucked in it. Baam was supposed to be the chosen character, not Rachel.]

Rachel is the irregular while Baam is the regular. [Notice how Baam was really fortuitous and all while Rachel was handicapped and only made it through the levels with the help of other people? It's like the tower is rejecting Rachel because she's an irregular and doesn't belong in the tower, but favoring Baam because he's a regular and belongs there.]

So far these recent chapters [75-77] really cleared up a lot of confusion. But yeah, she is jealous of Baam. But what I didn't really get was why so many rankers support Rachel, an irregular... It'll prolly get explained in the next few chapters I guess

yeah I also think baam wasn't really an irregular. I just don't get it why he was also given an irregular test at the start just like rachel if he was chosen. did he force the tower open after rachel got in? not sure.. also why is everyone else hellbent on getting rid of him.. so many questions..
