Literature: Paladin Academy

"The sword of the paladin is not a weapon, but a tool. A tool for them to use to protect the innocent and pass justice onto the wicked."
Blue Ghost, Chapter 4

Paladin Academy: A Playground-Inspired Story is a Web Serial Novel written by Silverraptor on the GiantITP Forums. Originally a story about some of Silverraptor's friends as newbies in a school of Paladins, it has expanded to include a grand cast of... well, perhaps a dozen.

The first arc involved an invasion from the Legions of Hell and a traitorous Senior Paladin attempting to slay our heroes, Viola and Kurama. Unsurprisingly, they survived. He didn't.

It can be read in this thread on the forums.
