[Crossover: Shizuo and Izaya] Made for Each Other

The whole story is around a hundred thousand words, maybe a little over, but no more than two hundred thousand. The main pairing is Shizuo and Izaya. The plot is a little sweet and not angsty. The secondary pairing is unknown, and there are countless hidden pairings for you to discover. "Huh? Those weird creatures? They can't hurt me anyway, so I'll just beat up every one that shows up." "Seriously, making my favorite humans their food? They're so ugly and disgusting. We should just wipe those things out already." "If even an alloy can't pierce my skin, what makes you think your teeth will work? Of course, that dead flea is the exception." "They don't even have the basic capacity for thought, just acting on instinct. Do you think I'd fall in love with a creature like that? Of course, Shizuo is still the one I hate most." When Ikebukuro's strongest became the strongest human, and Shinjuku's most evil became the most evil human, they became legends. A monster and a madman. Made for each other.
