Yoriko Narumi (鳴海 依子 Narumi Yoriko ) is a station attendant (conductor) at the Asashi Railways Shiratori Station. She is the crush and a co-worker of Yousuke Nakamura, and a character featured in the Line of Zero chapter.
Narumi is a woman noted to be very attractive, with an average build and height, and pronounced pinkish lips. She has light-colored hair which wears in a bun with a hair tie and she has short locks framing her face. She has dark-colored, sharp eyes.
Narumi appears to be a friendly, social and sometimes even playful woman. She is selfless and considerate, always trying to help other people. Narumi can also be very mature and level-headed, as she can handle stressful situations nicely despite feeling vexed inside. In some situations, like when Nakamura almost attacked her when he transformed into a devil, she didn't get scared or angry at all, she was just shocked and sad how he struggled so much. Despite Nakamura being a devil, she easily accepted him and cares about him deeply.
Story EditIn 2012, Narumi greeted her co-workers, Tamiya, and Yousuke Asami. Judging from Nakamura's reactions and how he couldn't even look her in the eyes, it was obvious that he has a crush on Narumi. After witnessing a businessman leap in front of a passing train with blood splattering everywhere, Narumi let her co-workers take of the situation while she went after Nakamura who had transformed to a devil, which she was unaware of. She tried talking to him, but he lost control and slammed her against a wall. He got himself to resist doing anything more and as he apologized, he ran off. When Nakamura walked down the tracks and saw the lights of an oncoming train, he accepted his fate. But just before the train hit, Narumi pushed him out of the way, and the both of them were soon rescued by Yuuki Anzai who had grabbed them and jumped to a telephone pole. Due to the shock, Narumi lost consciousness but when she came to, she appeared to be very relieved and happy to see Nakamura safe.
Narumi and Nakamura like each other, though this is more obvious from Nakamura's side. However, Narumi also has special feelings for him, as she worries and cares for him deeply, as she almost risked her life by saving him. She wasn't worried about herself, she was just happy that he was okay. She wasn't angry or even scared of him being a devil and when he attacked her, she quickly accepted everything and became very supportive of him. The only thing she did care about was the burden he was carrying. After the incident, she was especially happy that he finally made eye contact with her and expressed her desire for him to do it more, implying that she knew he liked her, and that she likes him as well. Soon after, they began dating.
