She's doing the old "hey that Reimu's little one's ice cream" routine and demanding that anon shares half of it. So next panel anon decides to "share" Reimu's ribbon by ripping off half of it.

Then of course the other half is idol little one's!
Yukkuri/To take it easy is meant to share with each other you know?!!
