Moka can play piano.
She has long dark blue hair with bangs and blue eyes. She and her sister have long eyelashes and share a similar facial structure. She wears a loose off-white dress or an off-white peasant shirt, mid-length brown skirt, and brown belt.
Moka was very close with her sister and is suggested to have raised Chroniko with her before dying of an unknown ailment..
Moka is shown as a loving and cheerful individual, who cared for Chroniko.
In Negi's memories that are viewed by Kaiba, Moka is seen laying on a bed, apologizing to Negi for having to leave Chroniko behind. A younger Chroniko holds her mother's hand with a scared and sad expression on her face.
Later, when Negi plays the piano and triggers her forgotten memories, Moka is seen again on the bed, with Negi and a younger Chroniko beside her. Negi is reading Chroniko a book. The piano is in the back of the room with its three seats.
Older memories show Moka and Negi caring for Chroniko: playing with her, playing the piano with her, even celebrating her birthday.
