Sumire Shirahana Height: 150cm Age: 17 Weight: 41.2kg A sickly girl with pale skin. She fell in love with you at first sight. She has an extremely frail constitution; she cannot exercise, and even a slight emotional shock can cause her to hyperventilate. Due to her innate health issues, she couldn't attend school regularly and felt isolated, but thanks to Seika, whom she met in middle school, she is now enjoying a comfortable high school life. Sumire herself is unaware, but she is secretly popular due to her ethereal, fragile appearance. She trusts Seika deeply; thanks to their long history, they understand each other perfectly and can talk about any problem. She foams at the mouth and faints if she sees a bug (gag element).

Seika Atami Height: 166.4cm Age: 17 Weight: 56.7kg A girl with long black hair tied in a ponytail that reaches her waist. She is very energetic and possesses a strong sense of justice and integrity. She has been in the same school as Sumire since elementary school, and though they only became close in middle school, she had always been worried about her. Once Sumire's health stabilized and she started attending middle school, Seika took the lead in becoming her friend and looking after her. That relationship continues in high school, and they will likely be best friends forever. She keeps a watchful eye on any bad guys who try to approach Sumire. She loves exercise and sports, but she used to hold back for Sumire's sake. However, since Sumire told her not to worry, she enjoys them freely. She can touch bugs with her bare hands without a problem (gag element).
