Saiki Kusuo[]
Chiyo fell in love with Kusuo for no reason. She is shown to have seen him in a different way and started to do tricks to get his attention. However, Kusuo, having no interest in romance, dodged her shenanigans by using his psychic abilities. She eventually gave up on Kusuo and moved on to Shinoda Takeru.[1]
Kaidou Shun[]
Chiyo had no feelings for Kaidou until he saved her from some punks at the beach, resulting in her falling in love with him.[2] She once hugged Kaidou when they were stranded on an island. In one chapter, she got the chance to confess her feelings to him which left him blushing and shocked; however this was undone because Kusuo reset time. Kusuo admitted that he felt bad for undoing her confession in a later conversation with Kusuke.[3]
Toritsuka Reita[]
Chiyo at first was another girl that Reita failed to flirt with, getting rejected. In later chapters, the two become acquainted because of their mutual desire to make the person they like fall for them. It was shown how the two went so far as to plan a test of courage but it later failed due to Kusuo's intervention.
Teruhashi Kokomi[]
Kokomi and Chiyo once have a feeling that they have love rivalry on Kusuo however, after some misunderstanding caused by Kusuo's powers, he was able to mend their friendship and the two got closer.[4] She was initially unaware of Kokomi's feelings for Kusuo, but eventually caught on and began encouraging her.
Makino Arisu[]
Chiyo and Arisu became friends since they were the only members of the occult club to show up at the club room. Chiyo's friendship with her changed the way Arisu looked, like how she stopped hiding her slanted eyes, unlike before when she covered them making her look almost like Sadako, and also made her more cheerful. In turn, Arisu made Chiyo develop a dark side and an interest in the occult. Kusuo found this aspect of their friendship disturbing.
Shinoda Takeru[]
Chiyo's ex-boyfriend. They started dating because of Takeru's pick-up lines. Takeru was eventually dumped by Chiyo after she got sick of his repetitive pick-up lines and bad habits, despite Kusuo's efforts to keep them together.[5]
Akanishi Shinichi[]
Another one of Chiyo's ex-boyfriends. He has neat appearance and was popular with girls but because of his debts on her, their relationship lasted only for a month.[6]
