Shadow Ooishi

Ooishi Kuraudo wearing a coat.

Coated Detective
Ooishi with his coat on, indicating that he rejects the need to feel coolness and seeking warmth instead. While always holding his coat, Ooishi will seldom put it on as it goes against his very self, only seen with it in special occasions like when visiting his friend's grave, so even in winter he'll just put on a longer-sleeved shirt.

As an idea frozen deep within the glacial's detective being, it is only able to manifest in his shadow self.
