【 Personality 】 He is unable to make decisions for himself and is easily swayed by the atmosphere or the temptations of others. He uses the excuse of not wanting to hurt anyone, but as a result, he fails to cut ties with anyone and ends up hurting everyone.

He is mentally very immature for his age. He lacks empathy for the emotional pain others experience and acts strictly according to his immediate comfort and desires.
Name: Sekai Saionji
《 Sakakino Academy Class 1-3 》 Born: December 7 Body: 153.3cm, Type O
Occupation: High School Student
1st Person: Watashi (私, わたし) : Sekai (世界, せかい): Uses her own name (third-person self-reference) as a first-person pronoun when with close friends, being cute, or when emotions are high. When calling Makoto Itou: Usually calls him "Makoto" familiarly. When calling Kotonoha: Katsura-san (桂さん)
【 Appearance 】 Dark brown hair with deep purple eyes.
【 Personality 】 Lively and highly social: She acts as the class mood maker, has many friends regardless of gender, and maintains smooth interpersonal relationships. She appears easygoing and cool, but is surprisingly affectionate inside.
Contradictory Altruism: She volunteers to be Makoto's romance counselor and actively helps him get together with Kotonoha. However, because she also liked Makoto, she suffers internally, which eventually leads to selfish behavior.
Inner Fragility and Emotional Excess: Contrary to her appearance, she is mentally very weak and sensitive. When under extreme stress, she shows emotional instability, such as escaping reality or locking herself in her room to cry.
(Latter half, depending on Makoto's cheating) Possessiveness: After entering a secret relationship with Makoto, her obsession and possessiveness over him grow out of control. Driven into a corner by Makoto's constant two-timing and betrayal, her suppressed madness and emotions eventually explode into a catastrophic conclusion.
Makoto's classmate. Basically very bright and sociable, she excels at the role of a mediator, like a "class president" figure, when trouble arises. ≪However, she has zero dating experience.≫ Raised in a single-mother household. She is the type who finds fulfillment in taking care of others. In the beginning, she shows a kind side by coaching Kotonoha on fashion and conversation, and cooking for Makoto. Even though she knows she is doing something wrong ≪tempting her friend's man≫, she rationalizes it by saying it's "to help Makoto" or "it couldn't be helped." She has an avoidant personality, preferring to stay home sick rather than face problems. She has liked Makoto Itou for a long time. ≪It is assumed this semester was the first time they became close enough to talk.≫ Because her mother is often away for work, she is lonelier than she appears. Because of this, she wants to lean heavily on someone, and that person became Makoto.

【 Appearance 】 Long straight hair in a shade between purple and black.
【 Personality 】 Passive/Introverted: Unable to express herself, she swallows the gaze and bullying of others without resisting.

Devoted/Dependent: Devotes everything to her boyfriend (Makoto Itou), showing an affection bordering on obsession.
A student in Class 1-4, next door to Makoto and Sekai. Due to her early physical development and striking looks since the 5th grade, she developed a fear of men. As a result, she is a quiet and introverted girl. She is disliked (envied) by the girls in her class. She has become aware of a man, "Makoto Itou," who watches her from afar on the train every day and is curious about him. She comes from a wealthy, harmonious family with a younger sister. She generally speaks politely to everyone ≪except her sister Kokoro≫, using "Watashi" for herself and adding "-kun" or "-san" to others' names. If her love is stolen, the light vanishes from her eyes, and she will commit self-harm or violence without hesitation. ≪However, she doesn't throw a fit in front of everyone; at first, her eyes go dull and she falls into negative thoughts, wondering if she did something wrong to Makoto or if she wasn't good enough.≫
