Sachiko Agou

Sachiko Agou (吾郷 佐知子 Agou Sachiko) is a second year at Hirefuri Middle and a member of the mahjong team.

Appearance
Sachiko is a 154 cm tall girl with light hair that is tied in pigtails.

Personality
According to Maiko Terado, Sachiko likes to make others frustrated. She is active and cheerful, and often likes to blurt out slightly stupid things. Her fellow second-year teammate Chantana Matsumoto is usually able to respond in a calm and smug manner, except during marriage talk.

Sachiko is obsessed with the idea of girls marrying girls. She considers herself married to Chantana, wants to befriend and marry Hayari Mizuhara, and immediately assumed an engagement announcement was coming when her elders told they had something to reveal.

Sachiko has a habit of drooling uncontrollably when desiring something, whether it be points on the mahjong table or girls to marry.

Playing Style/Abilities
Kayo Takeshige remarks that Sachiko gets waits that trigger Atama-hane at critical moments. In other words, she gets a Tenpai with the same wait as the player to her right. In this situation, if their shared winning tile is discarded by either of their two opponents, her win will override her opponent's.

Shimane Tournament Arc
In the finals of the Shimane middle school team tournament, Sachiko faced Hayari Mizuhara, Mio Bonkohara and Mizuki Aoto. Early in the game, she managed to win a Suuankou yakuman, sending her into a massive lead. However, her attempts to win quick, cheap hands later on in the game were unsuccesful, and Mio managed to overtake her by a slight margin by the last round. Since Komosawa Middle had already won two games, Mio's victory here would end the whole match. As a result, the two other players were both aiming to knock down Mio and make Sachiko win. While Sachiko herself also reached a comeback tenpai, ultimately Hayari won the hand and succeeded in making Sachiko the winner, extending the match to the Captain's round.

Mixed Training Camp Arc
Sachiko and Chantana walked together along the seaside to the training camp. Arriving in the evening of the first day, they immediately ran into Hayari and the rest of the Yumachi girls. Sachiko was flustered by Hayari's presence, and proceeded to drool over the prospect of befriending and marrying the her. Back in their room, Sachiko complains about not getting a bath and not getting there earlier. When Fuuka says she has something to tell them, Sachiko thinks it's a marriage proposal.

Later in the night, the seniors helps inform the juniors that they will not participate in the training camp. After their explanation they tell the girls that they'll leave Hirefuri's future in their hands. A tearful Sachiko tells them that next year they'll beat Komosawa.
