|Voiced by:||Jouji Nakata|
Kei Haramura is Nodoka Haramura's father. He works as an attorney and reluctantly tolerates his daughter's interest in mahjong because he believes it is only a game based on luck. His wife works as a public prosecutor and because of her work, the family often moves to a new prefecture every few years. Before settling in Nagano Prefecture, they previously lived in Nara Prefecture.
Kei is a stern looking man with short silver hair and brown eyes. In all of his appearances, he wears a suit and tie.
Kei desires for Nodoka to quit playing mahjong and move on to a preparatory school in Tokyo, thinking that the game will distract from her studies. He also scolds Nodoka for practicing mahjong late into the night, going to training camps and competing in mahjong tournaments, calling them "ridiculous", and believing that even if she makes friends, they are of no use to her in a "hick town" like the one where she lives
As Nodoka heads for school, Kei scolds her for staying up too late playing games.
Training Camp Arc
Before the camp we see Nodoka and Kei having a conversation about mahjong. Kei tries to convince Nodoka to give up mahjong and Nagano and move on to a preparatory school in Tokyo. He then says going to training camps and competing in mahjong tournaments is "ridiculous". When Nodoka mentions that she has friends there, Kei tells her that even if she makes friends, they are of no use to her in a "hick town" like the one where she lives. However when Nodoka promises to win the national tournament if it means she can stay, he says that he'll think about it if she can manage it.
