Daniel X Vol. 1 (manga)
When his parents are murdered by an intergalactic criminal, Daniel X vows to take on his father's role as Earth's sole Alien Hunter. But life isn't easy when you're a young boy on your own, tracking down the galaxy's deadliest outlaws.
Luckily, Daniel has a gift: the ability to create anything he can imagine - including his parents, his sister, and his best friends, who are there to help him along the way. But when Daniel decides to go up against the sixth-deadliest criminal on his hit list, he may find that even his awesome abilities just aren't up to the task!
