Connor Kluff コナー・クルフ

A young Letter Bee who was first seen in chapter 2, escorting Lag to his Bee job interview. Connor made regular deliveries to Cambel Litus as Lag was growing up, and seems to be popular with the townspeople. He has a hearty appetite and a stocky build, and tires easily. His Dingo is a hound dog named Gasu, who is skilled at tunnelling. Connor's Spirit Amber attack is called "Heart Land Mine", which he executes by setting shards of his "Appetite" on the ground and igniting them under the Gaichuu. Source: Wikipedia
