Miyuri Suzuhara is a classmate and friend of protagonist Chihaya Hiiragi, attending the same school and frequently interacting with Chihaya and their friend Sayaka Mizushiro. She demonstrates a protective and curious nature, particularly when encountering unusual events; for instance, she tries smoking out a strange creature spotted in the school changing room, initially mistaking it for a raccoon or alien.

She participates in group activities like searching for Chihaya's missing pet and discussing school matters. Miyuri expresses skepticism about new students such as Emi Kojima, questioning whether the seemingly unsociable transfer student would attend a sleepover at Sayaka's house. Her interactions include lighthearted moments like teasing Chihaya about a supposed date with Gou, Miyuri's twin brother, who assists at Chihaya's family café.

Miyuri's involvement extends to minor investigative actions, accompanying Chihaya during initial searches for the creature around school grounds and later expressing relief when Chihaya claims to have found it. Miyuri remains unaware of magical conflicts involving seed monsters or transformations.
