b4tans: Yuubari was infected by Yura disease.

Yeah, the joke is that candy "お菓子" can be pronounced the same as "fucked" "犯し". So, Yuubari took Samidare's request for candy or a trick will be played "that" way.

More commit a sexual crime (primarily rape) than just 'fuck', but yes.　There's also that 悪戯, in addition to being the benign 'trick' is also rape/molest/sexual misconduct.

So basically it's "If you don't rape me, I'm gonna rape you!"

bump.
