Higashikata, Daiya

The youngest of the Higashikata siblings. Norisuke tends to dote on her due to her nearly-blind vision, a result of falling into the future location of the Wall Eyes of Morioh in her younger years.

She likes western music in particular, owning a collection of vinyl records, and has a penchant for cutesy things.

She promptly develops a crush on Jousuke when he joins their family.

[Spoiler] Daiya is a Stand user who possesses California King Bed (カリフォルニア・キング・ベッドちゃん). Using her Stand, Daiya is able to extract the memories of people but only under certain conditions. Memories physically manifest as chess pieces. If a piece is destroyed, the particular memory it is will cease to exist forever, making it impossible for the original memory owner to remember it.

Daiya attempts to seduce Jousuke and eliminate his attraction towards Yasuho by using her Stand against him. [/Spoiler]

The pair later develop a more neutral, friendly relationship.
