The Blood-stained Lighter

A child was dropped off at our building later their parents jumped off a bridge leaving the child outside our door. My name is Doctor Levi and I am one of the scientists in this facility it seems like some little boy's parents just dropped him off thinking it was an orphanage...This is an Assasin Training Facility when I took a good look at the little boy he seemed to have black hair and green eyes and looked about 3 (people here range from 22 to 45 years ago) so we took him in it was extremely rare to have people this young and I gave him a room and started conducting experiments on him I injected him with three things: 40% was a fluid that makes his blood flammable, and because I accidentally put too much a single drop could destroy 3 a school, 10% of a stabilizer I made' and 50% of our newly made psychotic living organism or we gave him the name Leo. only 6 people with Leo exist due to the nature of this organism. When Leo is triggered not only does the personality change but the appearance too: the person's hair turns a snowy white color and the eyes become blood red (we thought it was cool). many things can trigger Leo and they all involve blood, for the boy whose name was revealed to be Loid if he were to see blood Leo would trigger. every Leo also has a different way and attraction of killing people depending on the host, Loid or Firebug as we'd call him is attracted to fire so we can make a guess that Leo would be a killer involved with only fire or an arsonist. we spent years training, electrocute and injecting him to make him qualified to become an assassin. finally, 11 years later he would be found by his family and taken away but he is still working for the organization we couldn't let a Leo holder get away like that.
