Hina Tougo

灯吾灯奈

Tsubaki’s little sister. Hina looks like an ordinary young girl, but she’s attuned to the supernatural and sensed the true identity of the goldfish spirits while in their human forms and vaguely warned Sora of the danger. Inexplicably, Hina also lied to keep Sora from meeting her brother. (Source: the manga habit)
