CSA0277: Aya: Stop laying about; there's investigative reporting to do!
Shenanigans in a Magical Forest
You check your notes in the BUNKACHOU to see what you've figured out. The answer is, quite frankly, not a whole lot. So ... YUKARI thought MASHA was dangerous, possibly for reasons which have to do with the fact that she was born with something as magical and complex as a CODEC DEVICE ... But she immediately dropped everything when it turned out that she was a STAGE 3 BOSS? And all this after promising you, in as many words, that this would be a better SCOOP than RUMIA YAGAMI forming her MALICIOUS COMPANIONSHIP?
YUKARI is always acting mysterious to the point of being cryptic, so not even a thousand-year-old TENGU like yourself can figure her out most of the time, but there's no way she could have possibly thought that you'd be satisfied with just this. Time to investigate some more!
