I really hope it's not editors/puplishers forcing Fukuda in this direction.
Anyway, she (Fukuda) seems to have wholeheartedly embraced the "romcom clichés". So, unless we get a big surprise I can see things going this way:
1. Marin will tell herself she/her cosplays are distraction Wakana from...
I just noticed that between last chapter's flashback (where Randa kinda, sorta confessed) and this chapter's, Randa got all those piercings. Not sure what to think about that.
So...third monster in and she in trouble for the second time.
I guess that shows that the manga can be taken as an argument for "streetwise over genius".
Remember how, in the manga, she nearly gets raped and kidnapped, only to be saved by the Elemental Cat of her friend, Leo? And how that turned her away from men and to cats?
Well that also happens in the LN. Only that Leo had a visible boner and, after killing the guy who tried to rape Aria...
In the LN during Aria's backstory.
Man, Ciel sure can fit alot of deathflags in a chapter.
Also, since dragon girl has visible nips in page 4, yet Aria doesn't in page 6, I am inclined to believe that elves don't have any.
