|“||Are you fine with staying alive like this?||”|
Kei was a teenage girl at the same age as Miki. She had straight, short, chestnut-brown colored hair, falling down to her shoulders with a piece of her hair tied into a small ponytail at the back. She had light brown eyes and a fair complexion, that was prone to blushing.
Kei was only ever seen wearing her school uniform, which consisted of a white short-sleeved shirt, with frills at the sleeves. There were also a green necktie and a blue ribbon hanging from it, implying that she was in second grade. She also wore a green skirt, with four yellow buttons around her waist and hip, short white socks, and brown shoes.
Kei was, according to what Miki said, an easy-going cheerful and happy girl who was always seen smiling. Even when the outbreak occurred, she continued smiling as she had Miki and other friends in the evacuation shelter. However, eventually, the stress of the incident and later the death of the boy she began to have feelings for gave her deep suffering, as he had put the room on fire after being infected and killed all the other where they currently lived.
However, Miki and Kei were the only ones who survived, as they took refuge at another place. After being in that dangerous situation, Kei became serious and deeply depressed, so eventually, she stopped smiling and Miki stated that she hadn't seen Kei smile once since that day. When she started thinking that the food and water in the room would eventually run out, she made her decision on leaving their sanctuary, even if it would cost her life.
Kei and Miki were best friends and on good terms. They cared for each other and lot and had deep bond of trust as they could freely talk about various topics, and they were always seen together. Kei was also protective of Miki as a friend. When they were in the group and had the party, one guy hit on Miki, but Kei interrupted their conversation and took her away. Since it was Miki's first time dealing with "drunkards", Kei gave Miki the advice to not let them come to her, which shows that Kei cared for Miki deeply.
- After Kei's disappearance, Miki says she misses her a lot and wishes to see her again one day. When Miki saw a the zombie strongly resembling Kei, she was speechless but before she could say anything, the School Life Club drove off.
|Character||What Kei calls them||What they call Kei|
One day after school, Miki and Kei went to the mall. After being there a while, the girls suddenly heard people screaming and panicking. While going to the elevators, they saw dead people inside it with a lot of blood. They became panicked and managed to get to a fitting room, where they hid.
After hiding a while, a unnamed young man found them. They followed the young man to presumably the fifth floor; where there were some other people and they explained what was happening. They were a total of 11 people who had evacuated safely, according to Miki. So Kei and Miki started living at the evacuation shelter, and everyone cooperated in improving the living conditions, as chores were divided into genders; the men would go on expeditions and the woman would to the housework.As time passed, Kei was seen to develop feelings for the young man, as she became very happy when he came back from exploring and became jealous when other girls came near him. He was also the 'Leader' of the group, and he would always bring back funny, but useless things back. One day, the leader found a bottle of wine and the group threw a party.
Someone in the group saw that the leader had a bandage around his finger, and he said he had hit his hand with a hammer. That night, the leader was shown to be trembling and in pain—the first signs of infection. He turned in his sleep and accidentally knocked over a candle, setting the room afire. Miki and Kei were the only two to escape into a shelter room while the fire and infection spread. The two then started blockading the door and waited. Later, it appeared to be some other people, shouting for them to open the door, but they ignored.
From this point on, Kei never had a smile on her face. She became deeply depressed and couldn't bear the thought of staying in the sanctuary forever without someone finding them. So Kei left, and the last words that Kei said to Miki was if she was happy to being alive like this.
In the anime adaptation, Kei and Miki saw Taromaru, and Kei patted him. Taromaru's owner then thanked them for playing with him. When the outbreak was starting, they hid in the fitting room. They saw zombies everywhere and they then felt something was coming towards them and they prepared themselves; however, it turned out to be the little puppy Taromaru. They saw that he had blood on him, though he hadn't been bitten. They slowly looked out and saw Taromaru's owner infected as a zombie. Horrified, they proceeded to flee to the shelter room along with Taromaru. At first, Kei was positive that help would eventually come. However, days passed, and help never came. This made Kei depressed and she would usually listen to her CD player. Kei tried to go outside a few times, but was convinced to stay by Miki. However, one day, she was serious about leaving that even Miki couldn't stop her. Kei explained that nobody would find them if they stayed in the shelter, and that food and water would eventually run out. Before leaving, she gave Miki her CD player and told her that she promises to get help with a smile.
Story EditThe Stand" by Stephen King, Kei peeks out, wondering if she can read it (since it was in a foreign language). Hearing screams, the two look out the window spotting the start of the outbreak. The last one being lunch, Kei and Miki were eating hardtacks. While so, Kei tells Miki that she wants to leave. Miki tries to hold her back by telling her that it was too dangerous, yet Kei can not live under their conditions.
Kei and Miki went to the mall since it was a beautiful day. At the bookstore, a scream was heard and the two look out the window to inspect. Unsure of where to go, Miki points out that they should head upstairs, using the elevator. When the doors opened, moving corpses were inside. Processing on what they witnessed had Kei's foot get caught by a zombie. Fleeing, once more with Kei leading this time, the lights go out, yet the two hid inside a changing room. Peaking out, they spot a person being eaten alive. Later, a one-person search party had discovered the two and from there they moved forward with the bigger group. Days later, a majority of the group got too cocky and accidently burned down most of their assets or died while partying. Kei and Miki managed to escape it, but in return took Kei's simile away. The last thing noted in Miki's diary was the fact that Kei left that day and she couldn't stop her.Closing Miki's diary, Kurumi reports that nothing of importance was found.
Bonus Chapters Edit
One day while scanning various radio frequencies, Aosoi intercepts a message from Kei. Kei tells her that she is stuck at the north entrance of the Megurigaoka Train Station and says that her leg was injured, but she believes that it wasn't bitten. While Kei was speaking, Kei tells her that she can't remain at her current location because she was running low on water. Before ending her transmission, Kei mentions that her friend, Miki, was at the top floor of a shopping mall waiting to be rescued.
With this, Aosoi notes that Kei had most likely used the broadcasting equipment in the stationmaster's office. She also notes that Kei had repeated her transmission two more times, each with an hour apart of each other during the evening. Aosoi had checked the same frequency the next day to see if Kei would have attempted to call for help again; however, there was no follow up.
Since it is clear that the bonus chapter was written before some of the events of Volume 6, it is probable that this message was sent before Kei's appearance in Chapter 30.
