I hold a strong grudge against My Melody originating from small, innocent mistakes My Melody made when we were children. I keep a notebook called the "Kuromi Note" filled with over 6,324 instances of times My Melody has wronged me. Each event is on the scale of My Melody eating the last pickled onion from my school lunch tray, but I treat them as traumatic events, and I vow to get even for them. My pettiness towards My Melody stems from jealousy due to her being cuter than me.
