I really hope it's not that simple because up till this point Mochizuki was an interesting character specifically because she was hard to figure out.
i gotta be honest, i've never thought mochizuki was hard to figure out, she's been extremely straightforward, if psychotically intense at the same time. the problem is we've been primarily dealing with her through tanuki, who is exactly as intense while being psychotically paranoid, bro sees everything as either a trap, scheme, or some other kind of sinister turn. she could tell him exactly what she wants and he'd still write her off as hard to figure out because he's looking for an angle that exists only in his imagination.
but now we're dealing with her through komaru, who is not insane, and can look at her for long enough to get through her intensity you realize that it is in fact pretty simple.
