My one and only

The "Demon"

The thought of losing tohka fills yukis head which unleashed the horn and tail "heh your still haven't developed your wings yet what a weakling I'll end this quickly" the mysterious man said "I made a promise to here that we'll be friends forever so I'm going to kill you" yuki said "quit talking and start fighting" the man said.the man charges into the ground almost hitting yuki he does this a couple damaging yuki badly "just die already " the man said."no have one trick up my sleeve" yuki said then he jumped up high and grabbed the man and brought him down which actually damaged him "I'll kill you" yuki screamed "heh you really are a weak demon aren't you losing control like this" the man said the man then coughed up blood due to the damage "good bye human world" the man tryed to speak but nothing could come out he new what was going on he used to much of his demon energy which his body couldn't handle that much burning out his body "I-I saved you tohka I may not make it out alive right now but just know I-I love you" yuki then collapse on the ground this was too much for his mind to handle was he a human or a demon yuki didn't know about his family to much cus they all died when he was around 4 or 5 so he doesn't know if they could be demons and just tryed giving him a normal life
