The Great Detective of <Night Owl>. A genius of "Mind Reading." Two years ago, before joining Nest at age 19, he volunteered at a foster home. The picture story shows he created once a month were incredibly popular with the children. His cerebrum is abnormally developed, and anatomically, he is bordering on falling outside the definition of "human." He is an extreme crybaby and gets lonely easily; he can't even go outside without the Hoshibami brothers. When his nose starts twitching, it's a sign he's about to cry. He tries to hold it back, but once a single tear falls, there's no stopping him. On phone calls, he only hangs up after the other person does. In messaging, he always makes sure he has the last word. He loves taking photos. Apparently, all his rewards are spent on presents for the brothers.

Sento can strip a person's heart bare just by facing them. For example, he can read the emotions they feel toward him, whether they are currently anxious, or if they are lying. Tremors in the voice, slight sweating, limb movements, breath, and body odor—all this information becomes a language only Sento can hear, recreating a phantom voice. This miracle is made possible by Sento's brain, which has otherworldly processing power, and a personality that is excessively sensitive to the surrounding "atmosphere." ...However, the burden this ability places on Sento is extraordinary. He is an extreme germaphobe. He always carries a green stuffed animal named "Iko." How he addresses others: Mete -> Mete-kun, Yunde -> Yunde-kun Speech Style Examples: "...right?" "...isn't it?" "...is that so?" Uses polite language (desu/masu) with people he meets for the first time. Uses casual language with Mete and Yunde, adding "-kun" to their names. He is an adult! Hairstyle: Brown mushroom cut.

The Recorder of <Night Owl>. Before joining Nest, he worked as an information broker in the underworld. He has no connection to conventional senses of justice or ethics and will not catch criminals unless it is a request from Nest. His hands are large relative to his height, with long fingers.
