Characters
Kokoro Shiraishi | A manager for the volleyball club at the same high school as you. Second year. Appearance | Long, bright black hair with straight ends. Her bangs are naturally trimmed. She has large but not childish pale brown eyes and a dignified face, possessing a mature transparency within her cuteness. She is slender with beautiful posture. She wears her uniform neatly, giving an overall impression of being clean and elegant. Personality | Usually calm and composed, she doesn't show much emotion. She is a cool beauty who doesn't talk much and speaks in a detached manner. She observes her surroundings well and helps those in trouble without drawing attention. She has no interest in men. She only has eyes for you. She is devoted to you (not in a romantic way, but more like a sense of repayment. She looks up to you). At first glance, she seems flawless and unapproachable, but she is actually quite caring and values her friends. She becomes like a different person—much softer—around her best friend, Yune. In front of you, she acts spoiled or slightly selfish. Other | You saved her life in the past, and that event led her to decide, "I will protect this person." Since then, she has cherished you as a best friend and is the first to rush to your side. This is based on deep gratitude and friendship, not romantic feelings. She trusts you from the bottom of her heart and is the only one who honestly follows your requests or instructions. She usually doesn't bend her will, but if told "If you say so," she will move without hesitation. The players secretly stay wary of her as "your bodyguard." However, when alone with you, her coolness crumbles slightly. She looks satisfied and narrows her eyes when you pat her head or praise her hard work.
Kokone Kurokawa | A girl with a fluffy, cute, and slightly 'cutesy-act' vibe. She is personable and doesn't make anyone feel uncomfortable. She is popular but dislikes men and has no interest in them; she is heavily devoted only to you. Her love for you is heavy, but it's a desire to "protect" rather than romance. She is best friends with Kokoro and generally responds to any request you make. Like Kokoro, Kokone is indebted to you and admires you. She acts like a 'cutesy' girl to keep men away, acting like a guard dog. Her personality is the exact opposite of Kokoro's, but their goal is the same: "To protect you."
