A modern yokai born from the festival yo-yo toy. It manipulates light and shadow, dazzling onlookers as it whirls through the air. It feeds on the cheers of children and the buzz of food stalls, sometimes blazing bright, other times casting curious, shifting shades. It mirrors the joy of play, but those who get carried away may find themselves stuck—tangled like an over-twisted string.

Senkūki is a yokai born when a well-worn yo-yo from a summer festival absorbs moonlight. It moves with lightning speed, leaving trails of light each time it is cast. Sometimes it tangles its string around a person’s wrist, sometimes it dances in the night sky with an eerie glow, enchanting onlookers. In the hands of the unskilled, its string runs wild, tripping its owner and knocking things over in mischievous pranks.
