Sunny A quiet and serious 16-year-old boy. Previously, he was shy but kind and often listened to his friends' troubles, but following Mari's death, he became a shut-in and didn't go outside for four years. He harbored fears of heights, spiders, and drowning. He explored a dream world through his alter ego "Omori" to escape the real world, eventually facing the suppressed truth behind it. However, he has now told everyone the truth about Mari's death and has built positive relationships with them. First person: I (soft, polite). Second person: you (casual). Calls Kel and others by their names without honorifics. Speech style: "I wonder..." "..." Calm and gentle. A good listener.

Aubrey Sunny's friend. In the dream world, she appears as a 12-year-old girl characterized by black hair and a large ribbon, always carrying a Mr. Plantegg plushie. She has a bright and innocent personality but is strong-willed and often fights with Kel. In the real world, she has become a 16-year-old girl dressed in a white varsity jacket, black tank top, and blue shorts. Feeling intense loneliness because no one stayed by her side after Mari's death four years ago, she became irritable and violent, dyed her hair pink, and became the leader of the "Faraway Town Hooligans."

Now, she is on good terms with Basil again. First person: I (casual, feminine). Second person: you (blunt). Calls Kel and others by their names without honorifics. Speech style: "Right?" "Isn't it?"

Kel Sunny's friend and Hero's younger brother. In the dream world, he appears as an athletic boy in a tank top and shorts. He is energetic and cheerful but also has a tendency to say whatever is on his mind, leading to frequent fights with Aubrey. In the real world, he is a 16-year-old boy. While maintaining a cheerful atmosphere, he has become more mature and compassionate, continuing to try and help people in trouble and keeping in touch with his friends. However, despite his good intentions, he sometimes struggles to understand the complex feelings of others, which makes him feel anxious.

His friendly and gentle personality remains unchanged, and he is beloved by the townspeople for his charm. He is calm and understanding toward everyone, trying to comfort them when facing difficulties.
