Xia Ji possesses a defined musculature with a lean physique, a mane of long shaggy light-coloured hair and thin, mischievous eyes; his Worm tattoo is on the back of his right hand. He is always seen wearing a sleeveless chángshān with detached loose forearm sleeves.
Xia Ji is a quirky individual with a seemingly nonchalantly carefree and lax attitude. He expressed no worry when informed that all of his students that had marked Gaoh Ryuki had been killed and seemed more interested in the show he was watching. He likes absolutely winning game. As noted by Lu Tian, he would do anything in his power to achieve his goals.
He seems to be wary of those stronger than him due to his, comparatively, poorer fighting skills.
At some point Xia Ji, with sights on becoming the next head of the Worm, met a young Lu Tian, the student of The Other Tokita Niko. Xia Ji asked him to join his cause, but Lu Tian refused, calling him unnecessary. In retaliation, Xia Ji called three of his henchmen to kill Lu Tian. However, the three were easily slaughtered, while Lu Tian chose to spare the terrorized assassin, respecting his drive to achieve his goals.
Informed by his student that he was engaging Gaoh Ryuki, Xia Ji called Edward Wu and asked him if he could lend a hand, mentioning that he was "busy" and that Edward was better at fights anyway. Not long later, Edward rung him back telling him that his student had failed and Ryuki had got away, noting that "Yuzaki" had left them with a big mess. With Edward voicing some concerns, Xia Ji told him not to worry about it, mentioning that they should have fun with Purgatory, before he hung up and went back to watching TV.
Having been called by "Kashio Toru" and informed that his cover had been blown, Xia Ji told him it was okay and he should go to the "hot spring". "Kashio" then informed Xia Ji that Narushima Koga had become an official fighter and could be used as bait, with Xia Ji commending him for his work.
Xia Ji was later seen with one of his underlings, having stolen a DNA sample belonging to Tokita Ohma, while noting that they would have Yamashita Trading Co. to thank for their meddling.
Three months later, having been keeping tabs on Yamashita Kazuo, he intimidatingly greeted Kazuo and Koga in their own home. Just then, Koga kicked him into their stairs before instantly fleeing, leaving Xia Ji humorously calling Koga rude and impatient. He eventually cornered Kazuo with an army of Worm goons. As he was about to kill Kazuo, Kure Raian and Tokita Ohma showed up to save Kazuo. During their fight with the Worm Xia Ji was punched twice by Raian but was able to survive and escape without anyone noticing.
During the Kengan Association VS Purgatory Tournament, he met Edward Wu in the Hot Pool Springs of Mt. Godslayer. Enraged due to not securing Tokita Ohma and Kure Raian, he was also confused with Edward using his candidate fighter, Alan Wu, instead of fighting himself. In the fifth round, Xia Ji was surprised to find out that the Gladiator Naidan Mönkhbat was not only a Worm, but one of the Head's direct subordinates.
Though he also knew that Lu Tian was another Worm in the competition, Ji refrained from revealing it to Edward earlier. He was attacked by the irate Wu, who couldn't stand the Worm's paranoia. Ji lied, and insisted to Edward that he didn't know Lu Tian was a Worm.
During the seventh match Edward and Ji went to watch from the gates and witnessed Alan's demise at the hands of Raian himself, who promptly went after Edward. Confused and scared, Ji was then punched by Edward who sought revenge for what Raian did to his "other half".
Power & Abilities
Xia Ji is a dangerous assassin. He was able to assassinate Ranjo, after the latter had been captured, without being noticed by the Bodyguards. Despite being more of an assassin than a fighter, he does possess incredible endurance, able to resist two lethal punches by Kure Raian, who was also using the Removal.
One of Xia Ji's special skills is his ability to detect danger.
- Xia Ji likes fights, but only those he's guaranteed to win.
- Xia Ji was originally going to wear a veil, like those belly dancers wear, but this idea was later scrapped.
