The character you're referring to is a fairy who takes on the form of a mouse with a hat and is known as Latifahs uncle. He bears a resemblance to Bonta-kun, a fictional mascot from Full Metal Panic? Fumoffu. This character has a mutual dislike towards Seiya.
Spoilers:
In episode 8 of the anime, he rants off at some high school girls while disguised as Seiya about how they know nothing of love and the suffering it can produce. He mentions watching the woman hes loved for ten years being married off to a guy he absolutely hated, then being entrusted with their daughter years later.Isuzu immediately asks if he was referring to Latifa, but Moffle claims he was just speaking hypothetically.
