Of Gods and Men by shadowphantomness is a Death Note Fan Fic crossing over with Harry Potter. It begins when Teru Mikami encounters some Death Eaters while riding the subway and from there he is introduced to the magical world. He informs Kira (Light Yagami) his lord and master of the goings on. When the Death Eaters target Kira, the Order of the Phoenix unknowingly saves them. Kira decides to "help" the Order, partly out of gratitude, but mostly because the Death Eaters are criminals who pose a threat to the perfect New World that Kira is creating...
Of Gods and Men provides examples of:
- Arbitrary Skepticism: Subverted, "The Death Note had already proved the existence of at least one type of magic, so Light did not want to discount others."
- Fetch Quest: Dumbledore sends Light and Mikami off to go find the horcruxes and is impressed and annoyed when they actually do.
- Fix Fic: Sirius and Dumbledore are still alive as of the ending too! And Mello and Matt! And things are peaceful for everybody too...
- The Gift: once awakened to his heritage, magic comes naturally to Mikami, while Light is more of a quick-study like Hermione.
- Go Through Me: "I will not let you harm him." Mikami, to Dumbledore, when Light is outed as Kira.
- Irony: Light and Mikami are unable to learn the Unforgivable Curses. The reason? Their will to kill isn't strong enough...
- Noble Demon: Light has the occasional Pet the Dog moment in this fic... and feels the need to explain his reasoning via inner monologue-it's for the sake of the Evil Plan not because he's going soft, damnit!
- Secret Legacy: In this ficverse Mikami's father was an auror of some renown.
- Story-Breaker Team-Up: when the Kiras enter the picture Harry, the Order and their petty morality become irrelevant.
- Terms of Endangerment: Inverted when Dumbledore repeatedly calls Light a "dear boy."
