—Kei to Miki Naoki, Chapter 12

Kei Shidō (祠堂 圭 Shidō Kei?) is a supporting character in the Gakkou Gurashi! series. She was a second-year student at Megurigaoka Private High School who was a close friend of Miki Naoki.

Appearance Edit


Kei's full appearance

Kei was a fair-skinned teenage girl that was prone to blushing with straight shoulder-length chestnut-brown hair that has a piece of her hair tied into a small ponytail at the back and light brown eyes.

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.

Personality Edit

Kei was, according to what Miki Naoki said, an easy-going, cheerful and happy girl who was always seen smiling. Even when the outbreak occurred, she continued smiling and being positive as she had Miki and other friends in the evacuation shelter. However, the stress of the incident and later, the death of the boy she had feelings for, eventually resulted in her suffering deeply.[1]

While Miki and Kei escaped the fire that killed the other mall survivors, Kei became deeply depressed; 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.[2]

History Edit

Manga Edit

While Miki Naoki and Kei were at the mall one day, chaos broke out and others began screaming and panicking. The two attempted to escape via the elevators, but couldn't, as the elevators were filled with dead bodies and zombies. Miki and Kei fled to a fitting room, where they hid until a young man found them.

Eleven people, including the young man, had evacuated safely, and explained the situation to Miki and Kei. The two lived in the evacuation center with the others, where the chores were divided by gender - men went out on expeditions, while women did the shelter chores.

Kei jealous

Kei being jealous.

As time passed, Kei developed romantic feelings for the man who rescued them; she was prone to blushing around him, became cheerful when he returned from the expeditions, and grew jealous when other girls came near him.[3][4] However, she did not express her feelings verbally.

When the man returned from a scavenge with a bottle of wine and the group threw a party, it was discovered that his hand was wounded; the man claimed he'd hit himself with a hammer. However, he had actually been bitten and turned in his sleep that night, knocking a candle over as he did so. Kei was distraught to see him burning in the fire, but Miki grabbed her and helped her flee to another room to escape the fire, with the two of them being the only survivors.

Following this, Kei fell into a deep depression and no longer smiled; she began to despair at both the loss of her crush and the possibility of never being found in the sanctuary. Eventually, she left the sanctuary, leaving Miki alone.

Anime Edit

While spending the day at the mall, Kei and Miki Naoki saw Taromaru; Kei petted him and his owner then thanked them for playing with him. After Miki picked up a book at the bookstore, the outbreak began, the mall was left in chaos, and Miki and Kei attempted to escape using the elevators; however, the elevators were filled with dead bodies, leading the girls to run and hide in a changing booth.

While hiding, Taromaru darted into the fitting room with them, and while he was bloody, he hadn't been bitten. However, when Miki and Kei peered outside, they saw his owner succumbing to the infection. Horrified, the two took Taromaru and fled to a back room in the mall that they used as their shelter.

Initially, Kei was positive that help would arrive soon, but as days passed with no signs of help, Kei became less optimistic and spent most of her time listening to her CD player. Becoming restless, she brought up the idea of leaving the shelter multiple times; though Miki convinced her to stay, Kei became increasingly agitated and distant from Miki.

Eventually, Kei became determined to leave the shelter, despite Miki's pleading. Kei explained that nobody would find them if they stayed in the shelter, and that food and water would eventually run out. Handing Miki her CD player for safekeeping, Kei told her with a smile that she would bring back help.

Story Edit

Manga Edit

Kei makes a few appearances in Miki Naoki's flashbacks:
  • When remembering Physical Education, Miki recalls running in the mall with Kei, being uncertain of where to go, and heading to the elevators with her.
  • When recalling English, Kei appears in Miki's memory as Miki picks out a foreign-language book, wondering if she can read it. As they begin to hear screams, the two look out the window to see the start of the outbreak.

Chapter 12
12 32A
Kurumi Ebisuzawa looked into Miki Naoki's student handbook to see if there was any information on her or any survivors left, and found that Miki had been using it as her diary.

On the day of the outbreak, Kei and Miki had been visiting the mall; when the infection broke out and the two were uncertain of where to go, Miki suggested the elevators. However, the elevators were filled with corpses and a zombie grabbed Kei's ankle. This prompted the two to flee again and hide in a fitting room, where they watched a person be bitten and turn.

Later, the two were discovered by a young man who was searching for other survivors. When he brought Miki and Kei to a sanctuary with eleven other survivors, Kei began to develop a crush on him. However, on one of his expeditions around the mall, he was bitten; after a party with the others, he turned in his sleep and knocked over a candle, setting fire to the room. While Miki and Kei escaped, Kei fell into a deep depression afterwards and Miki noted that she never smiled again after that.

Miki's last entry in her handbook simply reads, "Kei left today. I couldn't stop her." and Kurumi doesn't reveal this; she says nothing important was inside.

Chapter 16
16 10A
While Miki Naoki was confronting Yuki Takeya, Miki tells Yuki that she hasn't gone through what she had to go through back at the mall with Kei.

Chapter 30
30 28A
Before the School Life Club members leave, Kei makes an appearance, zombified. While Miki Naoki does notice, she hesitates before saying anything, and the group departs.

Chapter 73

After the School Life Club members return to the school and find safety in the Art Prep Room, Miki Naoki decides to venture out alone to find and collect the school's water. On the way back after opening the door of the bathroom, she looks out and sees the zombified Kei. Miki is unable to kill Kei and collapses to her knees, apologizing, while Kei reaches out her head to bite her.

Chapter 74

The zombified Kei collapses onto Miki Naoki after she is shot by the soldiers who came into the school.

Bonus Chapters Edit

Volume 6 Bonus

One day while scanning various radio frequencies, Shiiko Aosoi intercepts a message from Kei. Kei's message reveals 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. She also states that she can't remain at her current location because she is running low on water. Before ending her transmission, Kei mentions that her friend, Miki Naoki, 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.

Relationships Edit

Miki Naoki Edit

Kei and Miki were best friends and on good terms. The two deeply trusted and cared for each other, as they could freely talk about various topics and were always seen together. Kei was also protective of Miki, pulling her away from a drunk man that Miki was unsure of how to deal with, and telling her not to let "drunkards" come to her.[4]

After Kei's disappearance, Miki deeply misses Kei and wishes to see her again. However, when she saw a zombie that strongly resembled Kei wandering towards the school, Miki hesitates to speak up, most likely due to shock; the group drives away before Miki can comment.
