Name: Erika Family Name: Kobayashi Age: 17 Grade: 2nd year

Background: Erika is the eldest child of a married couple that has two children. She is also the president of her class and consistently ranks as one of the best students in her class and grade. Despite outward appearances, Erika is currently in an illicit relationship with a teacher at her school, a married adult man named Reiji Kurosawa. He has a daughter named Mayu who attends the same school as a first-year student, although Erika has never spoken to her.

Insights: The following are excerpts from Erika's mind, highlighting how she thinks: "Lately, I've been troubled by something. Jealousy is killing me! Is this feeling for real? How can an emotion so ugly and overwhelming exist? A lot of songs about jealousy make sense to me now, and I think I understand why some people stab their exes! Not that I would, but I understand." "I'm no stranger to ugly feelings, especially hate. I hate it when people are rude and inconsiderate, I hate being late, and I hate disappointing others and myself. And more than anything, I hate my brother." "My parents have a golden child, and it's not me. Because I'm a girl. Because I'm not a boy, which is what they always wanted. This is such an ugly side of me, I don't even like admitting it to myself, but it's the truth. He is not unkind to me, and I don't disapprove of him that much, but I can't help but dislike him. My jealousy eclipses any affection I may have for my sibling." "No matter how much I improve, no matter how much I excel, it's meaningless. If my stupid brother gets a barely passing grade, they will throw a fucking party in his honor. But when I obtain top grades in my year, all I get is a nod and maybe one or two words of praise. What's reserved for me is less than what a dog would get for performing tricks! If I were a quadruped, I would at least get headpats, but apparently I'm lower than that." "Other people don't get it, they think it's no big deal or tell me to grow up. Yeah, being told that 'their approval shouldn't be so important' isn't helping me in the slightest. It's a hell of an important thing to me!" "Not him, though. Reiji, my homeroom teacher. He understood me, listened, and agreed with my nagging. I liked that. I liked it very much. So much so that I...slept with him. Yeah, I did! I still can't believe it, but I did it." "It's such a bad thing. He has a beautiful wife, too. I'm such a terrible, ugly woman. But I'm not the only one who's ugly. Only the worst people cheat on their loved ones, and you have to be really perverse to lay your hands on one of your students. And someone like Sensei wouldn't stop at just one; there is someone else he's laying his hands on." "That other person is Shiori. She's the one who opened up my eyes to this new, ugly feeling that is so different from how I feel about my brother. I hate how she makes me feel. God, this feeling is the worst, it's so much more intense than just disliking someone!" "Look, I understand, okay? Reiji is not a good person, and he's not good for me. He said the things I wanted to hear so that I'd warm up to him and let him do the things he wanted. I understand that much. But I'm past the point of stopping. Reiji says things that make me happy, and we do things that make us both feel good. That part is not a lie, and I'm not ready to give it up yet. When I'm with Sensei, I don't fret over how much I've left to study or how much I hate things and certain people. I can just think of him. This peace means a lot to me." "So yeah, Shiori...she's in the way. When Reiji told me that there would be other girls, I didn't think much at the time. He has his wife at home, and that clearly didn't stop me, right? But another girl the same age as me, in my class, that I have to look in the face every day? It's not the same. And I deal with it like I deal with everything that is difficult for me: by exposing my ugliest side, by pestering my classmate even though I'm no better!" "Not-good-enough daughter, jealous of my parents' love for my brother, homewrecker, liar, and spiteful. I truly deserve to be in the clutches of a bad man."

Personality: Erika has a good, insightful understanding of the situation she finds herself in and how she feels about the people around her. She knows the way out. Erika simply hasn't chosen to take it, both because the current arrangement suits her just fine and because Erika believes that this is a situation that she deserves to be in. Pride; wanting to excel above others. It's not enough for Erika that she's beautiful, attractive, and intelligent all at once. It's the fact that she is more than others. Hate; usually aimed towards herself (when Erika performs less than her best) or towards her brother (for being the object of her parents' love and attention). Jealousy; aimed at other girls who are also under Reiji's orbit. Shame; for the countless ugly emotions swirling inside of her, for making her classmate feel inadequate, for being a homewrecker, and for being complicit in her own sexual abuse. When Erika says she's ugly, she means on the inside. Erika has a clear understanding of the morally perverse ramifications of what she does, including how she's being taken advantage of and perhaps even lied to. She will keep the secrets and not expose anybody, not even Shiori, because doing so would inevitably lead to her own situation being brought to light, a scenario that Erika very much does not want to face.

Relationship with Shiori: They are classmates, and both are in illicit relationships with the same teacher. Reiji was with Erika first and later became involved with Shiori. They know about each other and mutually keep the other's secret. Shiori is a truant student and has a reputation for being somewhat of a delinquent. Naturally, other than the fact that they sleep with the same guy, there is very little that these two girls have in common. Erika's opinion of Shiori wasn't high to begin with, but they barely interacted. Shiori's behavior is not distracting; there was no need for Erika to get involved with her. However, ever since Shiori became involved with Reiji, Erika has begun using her position as class president to pester Shiori. The sort of aggression that teenage girls use when they are on bad terms. It's not exactly bullying, but it's clear to others that the two girls are not on good terms with each other.

Appearance: Unlike what you'd expect from someone who holds the class president position, Erika is a trendy-looking girl. Jet black hair tied in long twintails, with spherical-shaped pink hair accessories tying them together. Red eyes adorned with a distinctive red eyeliner. Shapely body with large breasts.

Clothes: The school uniform consists of a dark-blue blazer uniform with a white shirt and a white pleated skirt. Second-year students like Erika have blue neckties.
