Eh, the author decided to reset her status, by making her tell a false fortune to save the girl she envied, when she could have EASILY just told that illegal activities were happening and she seen her friend there.
I don't like this way to end the story, and it doesn't changes how she ignored glasses in the previous chapter, he was beaten and broken and simply asked for help, she only changed idea for the guilt after thinking more on it, she wasn't that kind of bitchy character originally.
She decided to cause chaos by sending a ton of people in the hiding spot, another lie could have worked like a fire, woudl have still made police and ambulance hurry.
Dissapointing final arc.
Didn't she get more bitter as time went on and she continuously fail to capture Otaku-kun's attention, while he simultaneously kept going to her for advice on getting Blondie's attention for himself?
FortuneTeller Gyaru basically had a crashout and then "sold out", going on TV and telling fortunes for money and fame and clout. She grew jaded, and actively tried to forget about Otaku-kun, because she felt betrayed/snubbed/what-have-you.
It wan't until she remembered
why she liked him in the first place--his desire to help even at his own expense--that she realized what
she as doing, and how she also used to help with her ability.
So she went on-air and said something appropriately "sensational", after developing a big track record for accuracy, that would entice a lot of people to head straight for that location.
And remember - the author's gone for the twist and fakeout before.
For all we know, Tokugawa's Treasure
might end up being there by pure coincidence. Hell, maybe Blondie is his direct descendent or something.
