Oriko Mikuni

Из Puella Magi Wiki: "Sadness Prayer implies that Oriko considers herself similar to Rodion Raskolnikov of the Russian novel, Crime and Punishment. Both are well-educated, youthful, and arrogant, despite their state of poverty, both see themselves as entitled to do terrible things for the sake of the greater good, but ultimately are selfish and seek to validate themselves, both spend much of the story agonizing over their guilt, and both conclude the story suffering the consequences of their actions alongside the only person who ever truly loved them. This is reaffirmed in her personal memoria in Magia Record."
