Keigo Sakai

Keigo Sakai (酒井圭吾 Sakai Keigo) is a minor character in Bokutachi no Ikita Riyuu
==Appearance==
Keigo is a boy who is extremely short for his age, he is the shortest student in Class 2 and the second shortest character overall in the series after Saotome. He has black hair that reaches his chin in length and has parted bangs that are similar to Kazumi's. He wears large square glasses and his eyes are always closed so his eye color is unknown. He wears a basic light blue suit that consists of a coat with a single button, pants and a tie all in the same color along with a white shirt and black shoes
==Personality==
We don't know much about Keigo's personality due to how little we see of him while he's still human, but what we do know is that he is very logical, rational and seems to take studying very seriously. His mother signed him up for cram school and he often stresses about it, saying it'll start soon or he'll be late for it. He's a huge mama's boy due to how often he mentions his mother and even calls out "Mama.." several times for help once the Puppetmaster hits him with a mask. In Reason 63 when everything is back to normal, he takes a break from studying to spend time with his class on graduation day which shocks his friends, because he has seemingly never taken a breather and is the most serious person in Class 2 academically. Keigo says he will look at this as a review of the past 6 years
==Story==
Like everyone else from Class 2 at the beginning of the story, Keigo wakes up in his classroom scared and confused on the day of his class' graduation ceremony. Of all students he appears to panic about the situation the most, saying his mom will be angry if she finds out he missed cram school that day. Once the Puppetmaster uses the announcer and his voice blares through the speakers in the classroom, Keigo presses his hands against his head and asks what the 11 of them have done to deserve this and panics for the rest of the chapter
When Ryusei disappears in Reason 2 after the building has a power outage, the others propose they should go look for him and Keigo calls them insane for risking their lives with that monster out there, saying he has to look out for himself before anyone else. He then tells the rest of the class that the fastest way to fix this is the police and that there are phones in the teacher's room they could use since everyone's mobile phones were taken. He heads there along with Kine, Yashiro and the twins, Mii and Miu who also drag Kuonji with them. But what that small group of people didn't know is that all of the phone lines were cut and Ryusei discovered that while he flipped the switch for the breaker in the generator room far away from them. Back in the teacher's room, Keigo says the line on the phone he picked up is dead and the others confirm that all other phones in the room are out of order as well
Keigo then points out there's one more phone left and it was inside the principal's office. He pushes the door open but all hope is lost when he finds out the phone in the room has a missing receiver. Just then, the chair behind the principal's desk turns around revealing the tall shadow of someone sitting in it, holding the phone's missing receiver to their face and the students find a glimmer of hope, thinking that the principal was there and he could help them. Alas, that little light of hope quickly dims as it turns out that wasn't the school's principal, but the Puppetmaster. Everyone panics and while trying to escape the office, Keigo is caught and hit with a mask which causes him to start coughing excessively
When everyone ends up in the hallway in Reason 3, they helplessly stare at Keigo who keeps coughing and begging for help, calling out for his mother. As he's doing that, he coughs up a piece of brown string. When Akira asks the small boy if he's okay, he vomits a terrifying amount of string from his mouth, then the string starts coming out of his nose and even his eyes too. He vomits so hard that he flies up and the string wraps around his entire body until it completely covers him into what looks like a thick cocoon of brown string. The rest of the students watched in horror as the boy was struggling inside the string cocoon until it stopped moving and then dissolved in the air, making Keigo drop down on the ground with a loud clatter, although it seemed he would never be the same again. He was turned into a creepy life-sized doll with strangely textured hair that resembled blue spaghetti. The others couldn't believe their eyes as this seemed like it was something out of a nightmare. But this also led them to believe the doll they found of Mirai Himeno in their classroom earlier was the real deal and not just a sick joke. Everyone panics once more when the Puppetmaster darts after them and they leave Keigo's puppet behind in the hallway
The next time we see Keigo is in Reason 10, his doll was stuffed inside a locker and put into the highest spot among a large amount of lockers stacked like a game of Jenga. This turns out to be a trap set by the Puppetmaster because when Akira and the others (Miyao, Taiga and Chinatsu) see a hand sticking out from the top of the locker stack, they think someone is trapped in there and attempt saving them. After a bunch of the lockers are knocked down by an unknown shadowy figure using a broom and the top locker tumbles down, Akira suffers a critical head injury and gets rushed to the infirmary. When opened by Miyao, the one locker they were all worried about reveals Keigo's doll was hidden inside and it lunges for a second, scaring the emo boy before falling back to being motionless. They leave the puppet behind again and head elsewhere 
In Reason 16, a huge fire breaks out in the same place they had left the doll and Akira attempts to save it so it doesn't burn too. What Akira doesn't notice is that the Keigo doll was holding a lighter and was who started the fire in the first place with help from the Puppetmaster then pretended to lay motionless on the ground, but probably forgot to discard the lighter in time. We aren't shown this in the main story, but in Extra Reason 2 right after Tangesazen crashes through the window of the infirmary and attacks Class 3 then runs away with their phones, Saotome chases after him to retrieve her stolen tablet. She spots the Keigo doll talking to the Puppetmaster through a window in the yard while hiding behind some bushes and calls Keigo '4-eyed Mama's Boy' ('Mothercon Glasses' in Japanese version), then sees the tall figure hand the doll the lighter that was used to start the fire. The Puppetmaster spills a large amount of gasoline on the ground next to the tower of stacked lockers and Keigo sets it on fire, making Saotome question the motives of the small boy because she didn't know about students getting turned into dolls yet. Before she can comment further, she is knocked out by Tangesazen and brought inside the science room 
==Trivia==
* Keigo's student number is 12
* Keigo's implied to be into mature, older women
** Saotome also clearly calls him a 'Mothercon' in Extra Reason 2 but it's unknown if this is true since the girl likes to spread rumors about Class 2
