Relationships[]
Kisaragi Kaoru[]
Kaoru was very supportive to Haruta when his flower was yet to bloom, encouraging him and soothing him with his words. After the incident of Project Archive 1-15, in which Haruta let out his bottled feelings to Kaoru, they grew even closer to each other. When Haruta's flower finally bloomed in Project Archive 1-20, Kaoru was actually moved to tears. Kaoru also thinks of Haruta as the cutest member of Anthos*
Chise[]
Chise is Haruta's roommate, whom he always have to wake up in the morning and drag to the living room for breakfast. Despite Chise being a little bit troublesome, they're still very close. In Project Archive 1-14, Chise told Haruta to talk face-to-face with Kaoru to make up, and in Project Archive A 2-3, Haruta helped Chise getting through his anxiety by telling Lihito to talk to him.
Yuki Mahiro[]
Being in the same younger brother team as Haruta, Mahiro is very much fond of him and vice versa. They sometimes do silly things like making their Anthozoo piggyback carrying each other. Their combination name is called Rabion.
Sakurai Toki[]
Toki and Haruta used to live in the same orphanage. Haruta considered Toki to be his little brother, even dancing and performing to make the latter happy back when he was in a wheelchair. Not much is known about what made their relationship come to a sudden halt.

In season 3 it revealed that back when they were younger, Toki got adopted by a rich family, leaving Haruta alone in the orphanage. Haruta promised him that one day, after his new family helped him fix his legs, they'd become idols and find happiness together. Haruta said that he tried to contact Toki at his new home, but never got an answer. Toki believes Haruta left him all alone with his abusive step parents because he's never received any of his letters, causing him to despise his former "brother". He especially hates Haruta for becoming an idol without him, ignoring the fact that Haruta never got adopted and becoming an idol was his one and only chance to make a living. Haruta doesn't blame Toki for anything and instead breaks out into tears, apologizing over and over again and promising him that it's not too late yet and they can still become happy together, but before they can reconcile, Toki's mental and physical condition worsens and he's carried away by the production's doctors, while Haruta is rendered unconscious and they imply to delete his memory of their conversation.
