Hiroko has medium length-brown hair and dark eyes with glasses. She wears the standard Senriyama school uniform.
Hiroko is the one who informs her teammates about their opponents and how to deal with them. Her teammates compare her to a scientist. She has a growing interest in Arata Sagimori due to her different play style in every game. Thus, she is determined to analyze Arata as her new specimen.
Hiroko is typically serious and somewhat blunt, telling Izumi that there are many in her age group who are much better than she is, and that she should not focus too much on comparing herself to others.
Hiroko is in charge of making sure that Sera Eguchi wears her school uniform to matches.
Although she was born in Kobe, one cannot distinguish her from a student from Osaka.
Playing Style / Abilities
Her playing style is just like her personality, in that she likes to analyze her opponents during the match and counter it. While it gives her an advantage, if her analysis is wrong, or she has no information about the opponent, she will have difficulty responding to her opponent.
National Tournament Arc
Hiroko appears with her teammates coming back from sightseeing. When they go and check on their sickly member, she informs the others that they now have the tapes of their opponents matches. Afterwards she is shown making brief comments about Izumi Nijou.
Before the sergeant match of the second round, Sera Eguchi and the others were conversing about Yuu Matsumi. Hiroko had prepared Izumi a simulation program to help deal with her. She is shown next with her team discussing Yuu's playing style but notices that she changes her style to include every red tile and that their is not way to combat it. When Sera starts to leave for her match, Hiroko pulls her back and makes her change into her school uniform.
Her match was briefly shown but she did manage to gain points. In the anime after Achiga wins, Hiroko seemed a bit happy to have Arata Sagimori advance. And when Sera calls her out on this, embarrassed she informs her its for science.
Final Eight Arc
Hiroko appears with the rest of the Senriyama team walking towards their waiting room. She appears later in a flashback of Toki Onjouji's. Here she is playing Toki to see if she can see two turns into the future. During the last of Teru Miyanaga's turns as dealer, Toki again is on the verge of collapsing and has another flashback. Here Hiroko and the others are gathered around Toki's bed and tell her of the "Toki shift", which is a schedule for Senriyama to help her. Hiroko then tells her that she has worked out a list of recipes for the camp and that they really want to help Toki. She is then seen arguing with Izumi. Afterward we see flashes of the training camp. She is later seen with the rest of Senriyama going with Toki to the ambulance after she collapsed after her match. After Izumi's match, Hiroko welcomes her back. She then tells Izumi that third-years are generally better during the inter-high. While eating Izumi responds by telling her that there are some first year monsters out there. Hiroko agrees and tells her that even in her first year there were players such as Kei Arakawa, Koromo Amae, and Komaki Jindai. She then tells Izumi that she isn't even in the monster category even if she thinks herself one. She explains that Awai Oohoshi is probably the strongest first year, along with Saki Miyanaga and that Izumi shouldn't compare herself to others.
After giving Izumi Toki's room number, she continues talking but is cut off mid sentence as Izumi leaves. Hiroko notes that she should call some of the other members of the team to keep her company. After the lieutenant's match, she says that Sera should stop flirting on TV.At the start of her match, Hiroko says that she needs to get second place back and that Shiraitodai is the biggest obstacle. When Seiko Matano starts to make her move, Hiroko says that they aren't many records of her since she just started for Shiraitodai but has already devised a theory about her abilities. She then says that she will test her theory and then beat the hell out of her in the finals. Hiroko then says that she can't aviod Seiko's calls too much or it would wreck her hand and soon after Seiko calls again and just as she guessed Seiko won withing five turns of making three calls. When Seiko starts paying attention to Mairu Shirouzu, Hiroko wins and says that if she continues to let down her guard she'll sink her under. Later in the rounds Mairu and Seiko are battling while Hiroko observes them. Getting excited she says that their data is delicious and that she'll bleed every last drop out of them. During the east fourth round she starts analyzing Mairu saying that she should be panicking but that she is an ace that shows very little tells. She is then surprised when Arata wins but says that she was correct in figuring out that her playing style resembles bowling. However she notes that she mixes in a dated playing style but doesn't know. After another Mairu win, she says that she's winning too much. Her next hand she is a dealer and declare's riichi. Mairu then declares riichi but Seiko deals into Hiroko's hand and again the next round. She then realizes that she is within 600 pts of second place when Arata declare's riichi. Hiroko is again surprised by Arata when she wins on different tiles then she calculated for. After another Arata win, Hiroko speculates that she is going through a change a well. Later she says that with how strong Mairu is that there isn't much she can do. She then turns her attention to Arata and says that she is a serious danger now and that she couldn't collect much data on her thanks to Yuuka Morigaki. She then realizes that Arata's playing style sometimes resembles Harue Akado. Later the match ends with an Arata tsumo.
Back in the waiting room, Hiroko is greeted by Masae Atago and Sera. After learning that Ryuuka to the playing hall as soon as she arrived, she wondered if Ryuuka is up to playing. She is see after with Sera at the waiting room comment about Awai Double riichi, despite only seeing two times Awai techniques, she manage to see throughly to Awai double riichi can be stop by shifting the flow of the tiles which Senriyama's couch as well as her aunt Masae Atago comment on her amazing analysis. Though, she didn't manage to tell Ryuuka about it as the second renchan already start and hopes the best for Ryuuka. While studying Shizuno Takakamo, she notices that her abilities go along with the dice roll and the mountains that make up the tiles. After the loss she is seen crying and being comforted by Masae.
During the Side B semi-final vanguard match, Hiroko notes that Usuzan has a strong captain and vice captain but the rest are not that good. Hiroko also says that their sergeant player has put in a lot of work and that Usuzan's ace is very highly skilled. In the lieutenants match she discusses Choe Myeonghwa's abilities with Sera and offers to pay the money Hiroe Atago owes Sera, noting that 30 yen is a "cheap" amount.
National Championship Arc
During the vanguard match of the fifth place game, she is seen discussing the game with her teammates. Hiroko appears at the end of the sergeant match, scolding Sera for attempting to leave in the boys' uniform. Later, she greets the other vice-captains before they play, including her cousin Kinue Atago, and they banter about which is worse, playing after Hiroe as her sister or cousin, both agreeing that Kinue has it rougher, as all of her matches take place after Hiroe's. Everyone is weary of Mairu Shirouzu winning, as it's widely known that Shindouji's double aces are somehow connected. Unfortunately, Hiroko ends up playing into Mairu's damaten lessening the lead they have.
