De sa position pratique sur le toit, Reiko avait étudié les impacts de la bombe qui n'avait été larguée qu'il y a quelques minutes sur l'ensemble de la population scolaire. Son esprit avait erré, vide comme une feuille, toutes les explications logiques évadant son esprit amoureux de la logique. Fermant les yeux, Reiko se laissa quelques instants pour atténuer le choc qui avait été porté à son état d'esprit émotionnel. Quand elle les ouvrit, un regard obstiné et résolu de défiance contre leurs circonstances était tout ce qui glaçait sur ses yeux.
Un groupe de zombies avait par inadvertance commencé leur avance sur les vivants, et Kuro et Aki ont procédé à leur interceptation. Reiko s'est rapidement retirée, choisissant de se rendre utile en optimisant son cerveau. Les autres peuvent être laissés pour capitaliser sur leurs bras, quelque chose dont Reiko a cruellement manqué.
Vite, elle a scanné son environnement. D'après ce que ses yeux vifs pouvaient percer, il était évident qu'une grande partie du complexe de l'école avait été submergée. De plus, le fait que les zombies avaient réussi à se faufiler jusqu'au toit a suggéré à Reiko une seule chose : chaque étage contenait l'infecté. Et cela signifiait qu'ils auraient à construire un plan ingénieux pour naviguer leur chemin hors de l'école – aussi bien sûr, en minimisant les pertes de leur groupe. En supposant que tous ceux qui étaient présents aujourd'hui seraient prêts à rester ensemble.
Aki, l'élève joueur. Kuro et Megumi, les frères Hazekage. Paneru et Ben. Enfin – Reiko.
Quelles étaient les chances?
Entre-temps, Megumi et Ben étaient tous deux en danger immédiat. Ou pas, pensa-t-elle, renversant instantanément ses pensées. Elle était confiante qu'ils pouvaient gérer eux-mêmes, et avec tous les zombies distrait avec succès par ses camarades d'école, Reiko a vu sa chance, et elle l'a pris.
Avec un bang satisfaisant, Reiko ferme la porte à l'entrée du toit le plus proche de Megumi, Ben, Paneru et elle. Après quoi, elle a traîné la grosse poubelle (la même dans laquelle elle avait jeté son livre) et l'a placée devant la porte fermée, créant effectivement un blocage.
Suivant : La porte de la dernière entrée du côté opposé du toit.
C'est Kuro! Aki! – Elle a crié. Nous avons besoin de cette porte barricadée, immédiatement! » Puis, une pensée soudaine lui est venue, et elle s'est précipitée à Kuro, assez sensée pour s'arrêter à une distance confortable pour qu'elle ne se mette pas en travers du combat.
"Nous avons besoin de l'un d'eux vivant," Reiko a dit d'un ton résolu. Pour elle, ce n'était pas une demande mais un ordre. Elle espérait que Kuro s'était emparée de ses intentions inexprimées.
Reiko Kanzaki 

Age: 18
Gender: Female
Class: 3A
Personality
A self-interested and calculative character, and perpetually bored, Reiko navigates life with an almost uncanny confidence. Typically, she comes across as calm and emotionally self-contained, yet is capable of displaying bouts of brash stubbornness akin to that of a child. Reiko appears to be disinterested in interpersonal relationships, for she thrives inside her mind - an intellectual, observant and cautious individual, having little patience for anything superficial or repetitive. As many of her acquaintances would find, Reiko's habitual bluntness can be unnerving. She is sharp-witted, and quick to lash out with brazen comments. It is not unusual for one to be acutely aware of the psychological distance between them and her.
Reiko values creative and intellectual pursuits, thus constantly engaging herself in activities which involve the stimulation of her mind, easily breezing through the past academic years to obtain a placement in the top class. Oddly, she has a penchant for video games - and getting addicted to them - thus creating a paradoxical image of herself as a bright, studious individual.
Focused and independent, Reiko fails to see merit in taking orders from others. However, this aspect of her is more often than not, misunderstood. She does not view herself as superior, rather, it goes against her nature and personal beliefs. A pet peeve, if you would call it. Concerned about meeting or exceeding her personal standards than attempting to please other people, Reiko relishes situations or circumstances that challenge her intellectual curiosity.
Background
The Kanzakis are a prestigious, wealthy family, gaining their riches through the operation of a multinational company in the food industry. Selfish, arrogant and snobbish, Reiko’s parents although having studied at excellent and renowned universities, regarded the whole concept of education as a poor-man’s ideal – to them, the rich and sophisticated needed nothing else but lavish attention provided by a congregation of butlers, maids, and chauffeurs. They spent their days in leisure, encouraging Reiko to do the same. In true Reiko-fashion, she obstinately refused and rebelled - quite boldly too - against her parents’ protests. Not surprisingly, a lifestyle of sloth and gluttony disagreed with her intellectual pursuits. However, her scion status had exposed to her various elements of the sophisticated, high society, allowing her to select certain aspects from it which she found agreeable. In public, Reiko carries herself in a refined, dignified manner, albeit on several occasions choosing not to do so out of a personal whim. Her wealthy background, mannerisms and seemingly ‘high society’ interests have resulted in others generally unwilling to get close. As such, her close friends are few.
Skills
Geography: Reiko’s best subject. She is highly proficient at reading maps, and her memory capabilities allow her to excel in regurgitating facts and information, quite easily. She tops her class: every-single-time.
Mathematics: As a personal rule of thumb, Reiko abhors mathematics, finding no point in the learning of this subject at all. Her relatively good math scores are only a result of her obstinate refusal to give in to silly numbers.
Business Management: A subject in which she has no interest for, but compelled to take up for the sole purpose of ceasing her parents’ nagging. “If you insist on going to school, then make your time worthwhile and ensure you’ll be fit to replace us as CEO,” they said. Not that Reiko had the slightest interest in doing so. As of now, her grades in this subject are passable, yet far from impressive due to a general lack of interest in the corporate world.
Physical Education: Reiko’s physical fitness is laughable, considering the nature of all of her interests and hobbies. She detests strenuous activities, preferring to indulge in the invention of various sorts of schemes and tricks to get out of her PE classes. Therefore, it is hardly surprising that she gets winded easily.
Student Council (Extra-curricular): Reiko’s involvement as a member of the student council was out of sheer luck – or misfortune, as she’d prefer to put it. With her overall excellent grades, refined intellectual disposition and affluent background, the teachers saw in her a potential leader and promptly deposited her there. They, of course, were utterly wrong, just as how Reiko found her extra-curricular utterly boring, disliking the enclosed, annoying society of pretentious people almost as much as she disliked math. The only merit she saw out of it was that she was excused from having to deal with bossy student councillors.
Relationships/Friendships
Kurisa Shuiji: They do not know each other personally, but Reiko is familiar with his face and name - only because he is a persistent subject of conversation amongst the members of the student council. For causing 'physical harm' to other students, of course. Reiko, although has no qualms about his... hobbies, has inadvertently formed a distaste for Kurisa. And why so? Because she's absolutely sick of having to listen to the student council brats bitch about him on a regular basis, on the ethics of bullying, physically harming another, blablah, speaking as though they were basking on a pedestal of divine holiness and goodness. As such, Reiko has associated hours of horrendous ranting with the boy.
Shoske Kawahiru: Does not know him.
Kenny: Reiko, being in the same class as Kenny, has spoken to him on a few occasions. She treats him in a civil manner as how she would with any other individual, and finds her classmates' fear and distaste for Kenny rather illogical and sometimes, plain stupid. Her treatment of him goes as far as to accommodate his oddity by communicating with him in written notes. However, due to Kenny's apparent adverse behavior towards socialization, Reiko does not know him well enough to say that she knows him personally.
Utaho Rinnosuke: Quite similar to Kurisa, Utaho is also a subject of conversation amongst the student council, effectively earning Reiko's distaste as well. However, the fact that she is girl has earned some bias and merit in Reiko's eyes.
Akane Hetoshi: Reiko does not know her personally, but is familiar with her face and name. She is so far, duly impressed by Akane's consistent high grades, as well as several of her essays which she had gotten the opportunity to read. Shared by Reiko's teachers during class of course - 'model essays', they had said.
Mi Kiyoshi: Reiko vaguely remembers her during the school orientation organised by the student council for freshmen, during which she had taken class 1A around the school for an introductory tour.
Musato Kibaya: Does not know him personally but is aware of existence in school, largely because of his glaringly obvious stature that is quite hard to miss. Reiko has, however, taken mental notes of the occasions when Kibaya had interjected in bullying cases.
Aki Okumura: Does not know him.
Paneru Yagyū: Does not know him. 
Weapons: N/A
Other: They Ate Shoske
