MyKuromi

MyKuromi is the femslash ship between My Melody and Kuromi in the Sanrio fandom

Canon
Kuromi always thinks of herself as My Melody's rival. While My Melody thinks of the two of them as friends. Because, in fact, they actually don't hate each other. Although Kuromi quote-on-quote claims she is My Melody's "true rival." My Melody has warm feelings for Kuromi, but Kuromi's feelings are more inclined to rivalry, to make her seem "tough."

Onegai My Melody
Kuromi used to be friendly, but she has a revenge quest against My Melody, which makes her act like a villain to her. This is all because of some non-ill-intentioned, innocent mistakes My Melody made when her and Kuromi were children. Kuromi was so mad at My Melody for them that she keeps a notebook with her with all of the instances in which this occurred. Although My Melody's "mistakes" were harmless, Kuromi claims they were "traumatic" for her and swears to get revenge for them. However, later one the series implies that her revenge quest is more due to jealousy because My Melody is "cuter" than her, than because of actual hatred towards her.

The first time the two of them meet each other in the series, after a very long time, My Melody witnesses Kuromi getting a lot of high schoolers sucked into another dimension. As Kuromi enters the scene with an evil laugh, My Melody shouts her name. Kuromi says hi to her and says that she will not let My Melody interfere with her plans. My Melody gets closer to Kuromi and tells her that she shouldn't do bad things again. But Kuromi just laughs it off. Kuromi claims that she's helping a kid with no friends out, by trapping his potential friends there, so My Melody feels sympathy for her proposition and agrees. However, at that moment, Uta Yumeno lets My Melody know that trapping people is not frienship, so My Melody helps all the high schoolers be free, which makes Kumori even more mad.
