Momo Sakura

Momo is a short and young girl who has red eyes and hair color. She has short hair, pulled halfway into a ponytail like her older sister's. In The Different Story, she has long braided hair and appears to be a few years younger than Kyoko but more mature-looking in contrast to her original design. Though according to the artist, a year has passed and the change is due to her growth.

Momo is depicted as a lively child who loves playing and is respectful to others.

In the anime adaption of episode 7, Momo makes an appearance as a paper cut-out during Kyoko's backstory. It is explained how Momo died by Kyoko's wish for her father's sake. She is also one of the characters in the third drama CD, appearing when Kyoko brings Mami to her house in Kazamino City for dinner with her family.

In The Different Story, she makes her first appearance in chapter 2. She makes her first appearance when Kyoko and Mami arrive at Momo and Kyoko's house for dinner. Momo asked Mami to play with her but Mami refused politely. In chapter 3, she is shown walking outside her room after being accidentally woken up by her father. She goes back to sleep after she's told that everything is alright. In the same chapter, she is indirectly mentioned in a TV news reportage in Mitakihara City. There, it was announced that her residence in Kazamino City was caught in fire and she with her parents' bodies were discovered.

In Puella Magi Oriko☆Magica, she appears in a flashback, when Kyoko looks at Yuma and she is reminded of her little sister.
