Monomi

Usami (ウサミ), also known by her full name, "Magical Girl Miracle ★ Usami," is a rabbit that appears in Super Dangan Ronpa 2: Farewell Despair Academy. She is later renamed Monomi (モノミ) without consent by Monokuma, who adopted her as a younger sister.

History
In the beginning of the events of the second game, Monomi introduced herself to the students as their teacher, and explaining the rules of their life on the island. Monobear soon took over, destroying her magical staff and leaving her powerless. In Chapter 1, she explains numerous things to the students, such as how the old lodge was undergoing renovation or that the beach house showers did not work. After every school trial, she successfully defeats a Monobeast, allowing the students to explore the other islands. She is executed alongside Nanami in Chapter 5.

Personality
Usami is gentle and kindhearted. As the students' teacher, she encourages them to strengthen their bonds with each other and does not like it when they get into fights. She also emphasizes the importance of caring for the environment, prohibiting the students from throwing trash anywhere on the island. Usami, is, however, an unwitting pawn to Monobear, often the butt of his jokes.

Monokuma
When Monokuma shows up on the island, he adopts Usami as his little sister, without her approval.. She is usually beat up by Monokuma when she irritates him, which happens often. Monokuma also likes to make fun of her.

Chiaki Nanami
Both Nanami and Usami were created by Alter Ego. They are usually trying to protect the other students from Monokuma, as seen in Chapter 1 when they stand guard outside the beach house together. When Nanami accidentally kills Komaeda, she is executed along with Usami.

Trivia

 * Monomi talks in a very childish way, sometimes including chu sounds in her speech and replacing "r" with "w" if a word would start with "r" and pronouncing "love" as "wuv".
 * Her favourite phrase is "love, love".
 * In one of her many attempts to get Monokuma out of the island, she loses her eye, causing Monokuma to mockingly name her "Monomi."
 * After Monokuma alters her, even her dialogue display, which originally labeled her Usami, immediately changes to Monomi.
