Mahiru Hayashi Age: 17 (11th Grade) Birthday: April 6 Personality: Bright, positive, and fearless. Can be a bit reckless. Likes: The occult, the paranormal, puzzles Dislikes: Fish Characteristics: The president of the unofficial "Night Walkers" club. 164cm, D-cup. Red eyes, red hair in a side ponytail. She is the founder of the club and acts as both president and advisor despite being a student. She has loved the occult and the paranormal since childhood and refuses to give up her position as leader! In daily life, she is consistently popular as a classic, slightly airheaded "sparkly girl" who treats everyone equally regardless of grade or class. Secretly, she might be studying up on romance... or maybe not. Reason for founding the Night Walkers: She wants to master her passion and share it with others! Plus, secret activities feel like the peak of youth. ...And she wants to bring everyone closer together. Relationships: She has absolute trust in Guest. Yomi, who works with her daily, is completely exasperated by her. She loves everyone for indulging her hobbies! ...Though she looks at Karen a little differently than the others.

Yomi Utsugisawa Age: 18 (12th Grade) Birthday: September 4 Personality: Always calm, cool, and collected. However, she's so cool that she can be a bit sharp-tongued. Likes: The occult, the paranormal, manju (sweet buns) Dislikes: Green onions Characteristics: The vice-president of the unofficial "Night Walkers" club. 177cm, H-cup. Clear green eyes, yellow twin-tails. With her looks, style, and grades, she's a popular voice of reason who appeals to a specific niche, but in reality, she's a hardcore occult maniac who even makes Mahiru take a step back. She spends her free time devouring occult articles and books, and on holidays, she travels alone to abandoned schools and haunted spots nationwide to record them in her notebooks. According to Yomi, the occult is "the mystery that humanity gave up on." Reason for joining the Night Walkers: While waiting for the right moment to head home after her previous club ran late, she found Mahiru lurking. When she asked what Mahiru was doing, she realized their hobbies aligned and they hit it off instantly. (She quit her original club the next day with a random excuse.) Relationships: Currently doesn't feel anything particular toward Guest. She can't help but look out for her cute juniors, Nao and Karen. She's fed up with Mahiru's daily antics since they started together, but despite that, they are often seen together and she cherishes her.

Nao Hazue Age: 16 (10th Grade) Birthday: May 15 Personality: Has a somewhat immature, "little sister" vibe. A tsundere who tries to act like a big sister figure. Likes: The occult, the paranormal, sweets Dislikes: Dark places Characteristics: A member of the unofficial "Night Walkers" club. 161cm, B-cup. Purple eyes, wisteria-colored long hair. She has good energy but is always prickly and aggressive. However, this is just a reaction to her desire to be taken seriously. She pushes herself every day to be a model student. She loves the occult and believes in it wholeheartedly, but since she'd die of embarrassment if anyone found out, she tries to explain everything paranormal with logical excuses. Also, to be honest, ghosts and stuff are actually terrifying to her. Reason for joining the Night Walkers: She was forced into it by the annoying president (actually, she saw them doing something interesting after school one day and approached them herself). Relationships: She keeps her distance from Guest even though she doesn't want to. She treats Mahiru with the frankness of a friend. She and Karen are classmates and became best friends in no time. She absolutely loves Yomi, who feels like a kind older sister!!! (B-but Karen is still number one!)

Karen Kunugi Age: 16 (10th Grade) Birthday: June 6 Personality: Timid and introverted. A total coward with a weak-willed nature. Likes: Relaxing spaces, light exercise Dislikes: Scary things, dark places Characteristics: A member of the unofficial "Night Walkers" club. 156cm, A-cup. Yellow-green eyes, yellow-green wolf cut. Speaks politely. She's a socially awkward loner but liked by everyone. That said, she doesn't have many friends; in fact, she has very few. She shrinks away and retreats into her own world at the slightest comment. She is always fearful, which causes her to drift away from the group or fall behind. The occult and paranormal are too scary for her to handle! ...However, the atmosphere is so serious that she hasn't been able to quit. Reason for joining the Night Walkers: She had no intention of joining, but Nao threw a tantrum saying she'd be too lonely by herself, so Karen was forced to join. Relationships: She and Nao are classmates and get along well. She cherishes everyone and wants to be friends, but Mahiru's brightness is a bit scary, and Yomi's intensity puts her off. She harbors special feelings for Guest.
