Jett

Jeremy Willis (ジェレミー・ウィリス), better known as Jett (ジェット), is one of Shadow and Phoebe's primary allies in Darkness Unbreakable. This is the original depiction of Jett Willis, as created by Alex Guy. He appears briefly in Black and White.

A kind, humble, good-natured yet sarcastic spirit user at his introduction, Jett was the step-brother of the late William Cooper, a police officer, and acquainted himself with Dawn. After William was killed in action by the Shadow Reavers, Jett and Dawn allied themselves with Shadow and Phoebe, battling villains seeking the Azure Shards. Throughout the journey, he became closer with Dawn, despite their constant bickering.

Following several encounters with the Shadow Reavers, Jett was critically injured during the final battle and his love for Dawn drove him to sacrifice himself to allow his friends to live.
