Description
Flat is a supporting character from the anime Onegai My Melody, recognized as a small blue mouse with large ears that have yellow inner linings, a tiny yellow oval nose, and a long, slender tail often adorned with a small orange or pink ribbon. He originates from the magical world of Mariland and is one of the oldest characters in the larger Sanrio universe, having first appeared in 1976. He is best known for being the closest and most loyal animal friend to the series' protagonist, My Melody.

In terms of personality, Flat is generally depicted as kind, honest, and a little shy. While he has a gentle and caring nature, he is also notably more practical and level-headed than My Melody, whose relaxed and often oblivious attitude can sometimes frustrate him. He has a particular fondness for mushroom hunting and his favorite food is ice cream. Despite his reserved demeanor, Flat possesses surprisingly good social skills, especially concerning romantic matters, which he occasionally uses to offer advice to the human character Kakeru Kogure when Kakeru struggles to communicate with Uta Yumeno.

Flat’s primary role in the story is that of a steadfast companion and helper to My Melody. Whenever a crisis arises due to the magical curses cast by the antagonist Kuromi, My Melody often uses her magic to cast a spell on Flat, transforming him into a more capable form to help deal with the specific trouble. His deep affection for My Melody serves as a key aspect of his character and motivation. While he is typically supportive, there are recurring hints that his feelings for her are romantic. For instance, he is shown blushing when she hugs him and even directly asks her out on a date, demonstrating a personal investment beyond simple friendship.

Flat does not undergo a dramatic character arc or possess flashy magical abilities of his own. Instead, his development is tied to his role as a reliable and courageous partner. He consistently provides emotional support and, due to his ability to remain calm and think logically, often acts as a grounding presence for My Melody and other characters during chaotic situations. His courage is evident in his willingness to be the subject of My Melody’s spells, placing himself in harm's way to help his friends. Ultimately, his unwavering loyalty, bravery, and the gentle crush he harbors for My Melody define his contributions to the story.
