Colin Hayworth (コリン・ヘイワース) is the son of Harold and Sophia Hayworth.


Colin was raised with lots of love after his parents lost their firstborn, Renne. In Zero no Kiseki, Chapter 3: "Crossbell Anniversary Festival", Colin's natural curiosity moved him to follow a butterfly away from his parents and the crow.

He wound up being surrounded by monsters, only to be rescued by Renne. Unaware that he was saved by his older sister, he told his parents he was saved by a 'big sister with hair the colour of violet',[2] just like his father.[3]
