He was presented at Nana's restaurant as a degenerate lower number, beyond that, fortunately for Hina, he is one of the Legendary Red Barons possessing a powerful force for justicing his path.
His "Count" is, initially, -999.
Even though Nana stated that his Count stands for how many girls have turned him down, his count becomes -1000 after Hina calls him a liar and says that she hates him.
His "Ballot" count is 5700 and stands for how many heads he had cut off. In chapter 10, it states that he is acutally hiding his true power. During his battle, his count increases by 10 times, reaching the amount 57000.
It is revealed in the later chapter that Licht's real name was Sakai Rihito (坂井離人), Sakai Tokikaze's childhood friend and adopt brother. It is also showed he was shorter and even more pervert than he is in 300 years later, but he still cares about how people feeling is.
After he became the Red Baron, his appearance was slowly changed and his awareness was slowly controlled by the power and gone berserk, he catted Mizuka's left arm and killed his childhood friend, Tokikaze, which is causing the regret he has for 300 years.
