Mameruri Hazuki

An exceptionally skilled physician who also hints at being a mad scientist and a womanizer, she's a woman brimming with allure.

She seems to have arrived on the island before Mihiro and the others, enjoying a brief vacation before taking up her post at the island clinic.

Tall with an absurdly large bust and an elusive personality, she frequently crosses paths with the protagonist at the cafe where he works.

She seems to be observing Mihiro, Rina, and even Kouma's movements, though her true purpose remains unclear.

Possessing an extremely strong libido and no preference for gender, she attempts to force herself on the protagonist, Mihiro, and Rina alike.
