12 Moves Sideways by Silver Pard
- Crossover with Harry Potter
- Recommended by Aimsme, rewindreplayrepeat, feral, Fenro, Vash Ti
- Status: Complete
- Synopsis: After the Yotsuba Arc, Light becomes the new Defence Against the Dark Arts teacher. Harry decides he needs watching.
- Comments: Despite being short compared to most of the others on this list, 12 Moves Sideways packs a powerful punch. It's beautiful, almost wistful, with hints of something darker- it might just be because this Troper is a Light fan, but her heart broke at the Erised scene.
