YMMV / We All Need A Hero

• Alternate Character Interpretation: Is Light truly lying to protect Sayu? Or is he lying to deflect what he thinks is a manipulation attempt from Kazue because he truly believes she is Kira, perhaps only dating her because she is his chief suspect. Taking her refutation of Kira as her being on the defensive and her wanting to leave the case as a sign of evasion, especially since she does forensics to find the second Kira, something Kira would also want from his pov.
• Fridge Horror: As Kazue points out, as merciful as Sayu Kira is in comparison to canon light, the implications are still pretty horrific. Basically if you are found innocent in the court of law your neck is on the chopping block still from an anonymous kangaroo court and court of public opinion even if you may be innocent. A very dystopian reality.
  What gets me is how Kira says he won’t kill you if you turn yourself in…but really, you’re only safe if you’re found guilty and sentenced. If you’re actually innocent and the court acquits, then suddenly you’re back on the menu because you ‘escaped justice.’ And that’s not getting into how Kira’s trying to replace the court system with a panel of anonymous strangers on internet forums.
• Rooting for the Empire: With Sayu as Kira as unlike her brother Light Yagami, she is a far more well intentioned, merciful Kira that doesn’t have a God-complex and avoids killing innocents. As a result, a vast chunk of readers have expressed being Pro Sayu even if they weren’t Pro Light in Death Note proper.
