[WARNING! There will be cussing in this story, and since it's Izaya, maybe a bit of 'smexyness' in it as well. OH! Before I forget, some slight 'boy' x boy. Quotes on the first boy part because Mana is basically crossdressing, and nobody knows that :P]
{Oh, and trust me, the story is better than the description!}
