Description
Eriko Kuraishi is a demonfolk girl sporting light beige horns and a spiked purple tail, her purple eyes contrasting with short dark brown hair. She typically wears red and black armor accented with gold and wields a large double-bladed axe. Standing 154 cm tall and weighing 43 kg, her birthday is July 30 and her blood type is B. She belongs to the Twilight Caravan guild and attends Yae High School, enjoying hobbies like experimenting, sewing, and cooking.

Her personality exhibits obsessive, yandere tendencies, particularly focused on the amnesiac protagonist Yuuki. She relentlessly pursued him after finding him collapsed on the street. One notable incident involved her tying Yuuki up at the Twilight Caravan hospital and attempting to force an eternal bond with a cursed ring, thwarted only by the Gourmet Edifice guild. Her dialogue frequently expresses extreme possessiveness, including quotes like "Please look only at me" and "If an imposter of you were to appear, I might like to bind him up and keep him for my viewing pleasure," often accompanied by her distinctive "Kusu Kusu" giggle.

Despite this aggression, Eriko displays a contrasting kind and motherly side toward children. She remains dismissive of most people outside her immediate circle. Official sources mark sections detailing her background story in both the original game and Re:Dive as "To Be Added." Her relationships within Twilight Caravan—specifically Anna, Nanaka, Ruka, Mitsuki, and Shizuru—are similarly noted as undeveloped in available lore.

In combat, Eriko functions as a physical attacker wielding her axe. Her abilities involve self-sacrificial mechanics, draining her own HP to amplify her attack power. Her Union Burst, "Obsession+," temporarily boosts her physical attack and critical rate, with its effectiveness scaling inversely to her remaining health. This high-risk approach leaves her vulnerable. Her given name, Eriko, combines the kanji for "favor/benefit" (恵), "reason/logic" (理), and "child" (子), while her surname Kuraishi translates to "warehouse" (倉) and "stone" (石).
