Jink is a large man with wilted-leaf-coloured, short hair and a stern look. After becoming a guard, he usually carries a simple-looking longsword at his waist.
Jink is a petty and jealous man, which is exemplified by his bullying of Eugeo due to Alice spending more time with Eugeo than him. Jink is also arrogant and does not have much control over his emotions, as seen when he became furious and began shouting when he heard that Eugeo would be allowed to leave the village to attempt to become a guard at Zakkaria.
Jink disliked Eugeo, as the boy was always with Alice, the girl Jink himself liked. As a result, Jink resorted to bullying him on multiple occasions, such as hiding Eugeo's shoes for a day, putting bugs into Eugeo's meal bag, or taunting Eugeo when he was with Alice. Jink was the leader of a gang when he was young.
As he was the first son of the previous guard captain, he was assigned the Sacred Task of being a guard apprentice in the spring after reaching ten years of age, eventually succeeding his father as the captain of the guards. Although Jink's family was the most skilled in the village, they were also the most annoying family in the village due to their attitude.
When Eugeo brought Kirito to Rulid Village, they first met Jink at the guard sentry point and Eugeo explained that Kirito was a «Vecta's lost child», which was enough reason for Jink to allow Kirito into the village.
Several days later, after the Gigas Cedar was cut down and a party was held in the evening, Jink challenged Eugeo to a duel once he heard that Eugeo wanted to be a swordsman and that he would be given the right to leave for the Norlangarth North Area Swordsmanship Competition in Zakkaria before him. During the duel, Jink appeared as if he was going to strike diagonally from the top-right, but he instead swung horizontally from the right. However, this feint did not affect Eugeo, who chose to use «Slant» instead of «Horizontal» and successfully deflected Jink's sword, winning the duel. The stunned Jink and his father then backed away from Eugeo and the party continued until the 10 o'clock bell struck.
