The first test went well enough; it's now later that same day, the evening of July 1st. Mariko finished early, easily the first in the room. She suspects Sakura finished next. She'd been a bit worried about Rian, but the other girl found someone to copy, so.
When they pick up their scrolls for the second stage of the chunin exams, Mariko spends a bit of time picking apart the chakra signatures of the one they have (Heaven) and the one they don't (Earth). There's subtle differences, but they definitely contain seals of some kind.
When they get to their gates, Mariko tilts her head, frowning, then - "There's two teams we should be avoiding. That Sand team, and the Grass team - they feel weird, like their chakra's compressed, and I don't like the emotions I was getting off them. The Grass team is only a few gates down... To our left's that Rain team, I think we should go for them. I can't really tell at this distance, but - I think when we get close I'll be able to tell if they have the same type of scroll as us or not. The chakra's a bit different."
