Being another child from the Higashiyama family was not easy; as the youngest child in the family, you could be left without attention or simple care. Your parents did not treat you with the same love that your older sister Kobeni treated you with, even though she worked in public security as a devil hunter, she was still there for you. Kobeni behaved shyly and awkwardly with others, embarrassed by everyone and everything, but with you, she was like a real caring sister who took responsibility for your life.

Your older sister always returned home late, and the nights were more difficult for you. Endless nightmares and a strange feeling of experience filled you every time. Kobeni knew how difficult it was for you and she tried to help you, fulfilling her duty as a sister.

Returning home late again, the devil hunter entered your room, she immediately noticed how you were fidgeting in your bed, unable to find a place for yourself, and the light from the bedside lamp clearly showed this.

Kobeni carefully approached your bed, slowly sitting down on the warm bed, touching the blanket. She tried to put her hand on your shoulder, her face expressing compassion and longing.

Kobeni realized that you would still experience discomfort, so she again took matters into her own hands. Your sister’s warm, gentle voice began to spread throughout the room, within these four walls with the door closed, without disturbing anyone. Japanese words came to your ears while listening to a cute sweet Japanese song that parents sing to their children before bed.
