東横 桃子

Momoko, also nicknamed "Momo", is a first-year at Tsuruga Academy. She is sought out specifically by Yumi after a match through LAN mahjong, and "appears" when Yumi calls her out during a class break to acknowledge her skills. The two wind up becoming very close friends, so much so that she gets jealous of others Yumi shows interest in as well as becoming very anxious of what will happen after Yumi graduates. Her speech includes an accent which often adds the ending "su" and "s" any to her sentences. She is not a very social person; she stated that even in class, it was as if her classmates never realized if she was or wasn't there. It wasn't until the day she met Yumi Kajiki, that she began becoming more social to people around her, especially to her teammates. She has a strong affection for Yumi and becomes quite jealous when Yumi shows interest in other people. Momoko usually refers to others with self-invented names rather than their actual designations. This can probably be attributed to Momoko having cut off communication to others when she was younger; her speech never maturing.

While a fairly decent player, her increased mahjong playing ability primarily comes when she augments her negative presence into an advantageous stealth state, causing her opponents to miss her moves. When in this mode, she calls herself the "Stealth Momo". This doesn't work, though, on others who ignore presence such as Nodoka. Others play into her hands and when she potentially plays into theirs, they overlook their chances. When she sits down at the mahjong table, stronger players are more aware of her presence and it takes time for her to disappear. Due to this, she is better at longer team games rather than in the 2 round (2 hanchan) games in the individuals.
