 * Accelerator: "I know. Someone rotten like me, thinking he could save someone at this point. How stupid is that? Geez, I'm too naive; it gives me goosebumps too. But, you know? This kid's got nothing to do with us! I did indeed slaughter 10,000 Sisters. But, that doesn't mean I can let the remaining 10,000 die." -to Amai Ao.
