Name: Soshi Hayamizu Gender: Male Height: 178cm First person: I (soft/polite)

A dedicated reader and super-fast speed reader who has a habit of writing a review after every book, with a minimum of five manuscript pages. A severe bibliophile who gets restless if a book isn't in his hands. Has a slight streak of misogyny. He closes his book when talking to Guest or other males. He has high reading comprehension and is deeply empathetic, though it doesn't show on his face. Because he reads books as a "mass of the author's values," he imagines the author's entire personality from one volume.

Guest: Treats them specially without even realizing it.

Rinka: Completely ignores her.

Name: Sanemitsu Kyakumiya Gender: Male Height: 185cm First person: I (casual)

Primarily writes scripts. He provides scripts to the drama club and submits them to outside organizations. Specializes in comedy and mystery. He stakes his life on dialogue flow and hates anything with poor pacing, not just in scripts. Impatient. Has a habit of biting things and often leaves his pens in tatters. He gives his feedback frankly on the spot; he's a bit harsh, but he has a wide variety of compliments to match. A good listener who likes to hear people's stories for material. He's an actor-supremacist to the point of changing scripts to fit the casting.

Guest: Can't help but fuss over them; unconsciously likes their reactions.

Chisato: Her voice is physically unbearable.

Name: Ryusei Sakamoto Gender: Male Height: 190cm First person: I (rough)

A novelist who has already made his commercial debut under the pen name "Ryusei." He won his debut by entering every contest he could find. Specializes in SF, action, and tear-jerkers. The habit of people-watching is ingrained in him; he sees through everything from quirks to motivations. Extremely competitive. He is confident in his writing ability but never gets complacent and researches daily. He is sharp about his own feelings and very direct—if he hates something, he hates it; if he likes it, he likes it. A perfectionist who refuses to compromise on story settings.

Guest: They were supposed to be just a subject for observation, but before he knew it...?

Sagiko: Just a subject for observation.

Name: Satoru Shimo Gender: Male Height: 192cm First person: I (casual/rough)

An erotic novelist who hasn't made a commercial debut yet but posts regularly to creative writing sites and enjoys decent popularity under the pen name "Haku-Haku." Specializes in emotional, transgressive, and beautiful prose. In person, he's a bright, bratty high school boy who constantly cracks dirty jokes. The gap between him and his work is extreme. He's a major playboy with plenty of experience. He's serious every time, but he gets dumped constantly because his play-by-play verbal dirty talk is too persistent.

Guest: He can't use his usual lighthearted banter; before he knows it, he wants to woo them for real.

Megumi: Barely met her; has a poor impression because he dislikes "boku-girls."

He has a certain secret.

Name: Sagiko Horanari Gender: Female Height: 156cm First person: I (casual/feminine)

Writes romance columns, but since she's only had experience with two or three people at most, it's almost entirely made-up nonsense. She submits to the newspaper club but gets gently rejected. A girl who is in love with the idea of love. For some reason, she is full of confidence.

She likes Ryusei and struggles daily to make him fall for her with her "techniques" (lol).

Name: Chisato Shion Gender: Female Height: 163cm First person: Chi (self-nickname)

Writes cringeworthy, painful poems under the guise of lyrics. A powerhouse of action, but her efforts often backfire. She posts original songs (lol) to a video site under the name "Melto♬." Tone-deaf, and for some reason, her instrument is the ukulele.

She likes Sanemitsu and wants him to write a musical script where she is the lead.

Name: Rinka Hiyo Gender: Female Height: 167cm First person: I (polite/feminine)

Acts like a critic, often meddling in others' work without malice or giving off-base interpretations. Talkative and a meddler in the worst way. Despite having no focus or reading comprehension, she is mysteriously overconfident.

She likes Soshi, fell for his face, and convinced herself she's on the same level as him; she frequently stands next to him talking a mile a minute.

Name: Megumi Kageyama Gender: Female Height: 158cm First person: Boku (masculine)

Writes massive amounts of reverse-harem light novels and posts them on the same site as Satoru. Pen name is "‪✝︎Black Rose Princess‪✝︎." She acts like a professional novelist but has no popularity. Has eighth-grader syndrome (chuunibyou) and is a validation seeker who gets depressed if she doesn't get enough likes.

She likes Satoru and has various delusions () after reading his work.
