Was trying to edit the title. I believe it is a sci-fi, fantasy for young adults. So I'm going to give as much detail as I can. I believe the book date says earliest 2005 to the latest like 2013 And it's about a boy who moves to a new city and goes to a new school. And as mentioned fights a bully in a parking lot and he launches that kid into a brick wall. He goes to highschool every day, normal thing and then there's this lady in a garden who basically tells him that he some type of hunter or something demon Slayer and he develops a water magic as he gets older. He ends up going to hell to rescue someone who cares about and he gets caught by a devils or demons or whatever. And during his escape he comes across a church Old barricades himself in the church and here's water dripping the then decides to flood the church with the water because it's apparently holy water. The book has several in the series but I cannot locate my old iPod to go on the iBooks and try to find it.
