Tome - the eccentric owner of the Spirits and Such Investigation Agency. Strangely, she likes her clients to call her "Tome-hakase" (though everybody overestimates how much she knows about the occult!). Her ultimate goal in her adventures is to contact extraterrestrial life

Serizawa - Tome's shy and anxious apprentice, his instability drove him to become a shut-in for an entire year. He hopes that by working alongside this lady he'll be able to control himself one day. For the current moment, he is trying to chill out and make friends in his extra classes

Mezato - part-time journalist, full-time cult leader. After Serizawa accidentally ruins her latest scheme, she starts trying to mold him into something much bigger: Psycho Helmet, the god she intends to create and the one who'll change the world. Tome isn't a fan of this idea, but Mezato still makes them company in the agency, and Serizawa finds her too "nice" to break her heart...

Reigen - a meddlesome first year, he is constantly in search of new ways to make his life less dull. He claims this will make him big in the future. His current pet project is readjusting Serizawa to society, but its unclear whether he is a trustworthy source for anything, since he has just entered middle school and won't even join a club...

Toichiro - the unapproachable president of Sansho Pepper High's Student Council, he is secretly being hunted down by the terrorist organization Pulsar. While he opposes their world domination plan, its just because Toichiro thinks he'll do better. Still, maybe with a few pushes (even more from a certain girl from his class), he'll learn to get along with others

Shigeo - more known as Mob, by day he is a meek househusband, and by night, a bodyguard with frightening power. In the past, he was Tome's fellow club member. He strongly avoids violence (and his emotions even more), but he won't hesitate to take action when his brother or Teru are in risk
