has short hair and is generally sweeter than her twin, but develops a bad attitude whenever Nana takes credit for what she does; she shares a connection to plant life. She also has a strong attraction towards Rito (similar to Lala's, but with a more lustful desire), stating how his facial expressions are lovely, letting him touch her tail, and even becoming more aroused when Nana refers to him as a "beast". At times, she would even sneak into Rito's bed at night, but when asked why she does that, she simply replies that she is sometimes half asleep and unintentionally ends up in Rito's bed. At one time, she nearly stated how jealous she was of Lala that Rito's hand was stuck to her tail. Her tail is also able to shoot out lightning.
Like her sisters, she has a cell phone capable of transporting objects. However, instead of gadgets, Momo summons plants.
