原文Justin's personality can be described as polite and zealous. He is seen smiling numerous times in the series and addresses his peers and enemies with suffixes. He does not openly look down on anyone, nor chastises them, yet is prepared to kill should he be given the orders by Shinigami.
One of Justin's most notable characteristics is his devout faith in Shinigami to whom prays and give thanks for everything. His faith affects the clothes he wears and how he typically speaks, using chiefly religious terms even within his normal sentences.
Another characteristic is his earphones, which he is never seen without and has the volume of the music turned up rather high. The volume is so high, it prevents him from hearing when people speak to him. Because of this, or out of necessity, Justin has the ability to read lips, but due to his constant usage of earphones and Shinigami wearing a mask, he cannot understand Shinigami. This also applies to Tezca Tlipoca, who spoke to Justin on several occasions in the past but never realized that Justin could not actually hear him. Another drawback is that he tends to speak loudly due to his constant use of headphones. This also annoys other people who are not aware that he is capable of reading lips, leading them to think that he is ignoring them.
译文JUSTIN的性格可以说是狂热而又文雅的。（这句不懂）他既不公开小看别人，也不惩罚他们除非得到了死神的命令。Justin最突出的的特点是他虔诚的信仰和凡事谢恩。这些信仰使他身着神父装，在说话时用一些宗教用语。
Justin另一大特色就是他的耳机，他从来不摘下耳机并且把音量调到最大以至于他从来听不到外界的人说话。就因为如此，Justin会读唇术，但对于像死神那样有面具的人，他还是不知道他们再说什么。还有Tezca Tlipoca，他从来没有意识到在大多数场合下Justin并没有听到他说些什么。另外，他在戴着耳机的同时嗓门儿很大以至于让那些不知道他会读唇术的人很恼火，并且有一种被无视的感觉（锯子哥？）
