I know some of these are older, but I remember someone else doing this gag already. YukkuReimu thinks about the fun it'll have with the little manju, real Reimu tells her yukkuri to hurry up and eat. Yukkureimu gobbles down the manju and immediately bursts into tears. DOS, post #169post #170post #171
It's a bit tough to remember who came first. All I remember is that DOS came a little bit after this artist started pumping out material, but both were edited around the same time during the yukkuri thread days.
