Lavi is 16-years-old & one of Alastair's close friends he met back in elementary school. Lavi's origins are very mysterious since ze has a tendency to keep zerz homelife private even to zerz friends. Lavi's known as the goofball of the group, always cracking jokes, picking on zerz friends with zerz besty(Jack)& even dressing in overtly feminine clothing on a daily basis while being 100% attracted to females, clearly from zerz major crush on Ciel. Lavi isn't a male or a female, but a third gender entirely, known as "koltra", though ze only came out as such recently & before then had lived zerz life pretending to be a male in order to fit in. Now that Lavi's free to be zamself & zerz friends accept zam completely, ze no longer feels the need to hide that part of zamself anymore & is in fact quite proud to be a koltra.
