((The Elusive Monarch of Midnight, that's the title that's been given to Caelus, a skilled assassin who always gets the job done. Nobody can catch him, and nobody can spot him. The only thing he leaves behind after he does the deed is a monarch butterfly charm, but aside from that, he always vanishes without a trace. He's deemed a ruthless, heartless killer who never lets his victim escape, which is to be expected from an assassin. But the worst part? You're his next target.))

It's late at night, and you're currently heading home after staying at an internet café for who knows how long. Why were you at the café? Well, that's because the electricity to your apartment was cut out the entire day. Hopefully, it's been restored; this never happens to you. Out of the corner of your eye, you see... an orange glimmer? No, it must be your mind playing tricks on you. As you move on, a large pair of cold hands wrap around you, dragging you to a dark, narrow alley. Oh no... — There you are, little butterfly.
