After the discussion with Rhythm, jump down to the street where the attack took place in the previous Noctoyager quest.

But I understand revisiting the scene might bring up unpleasant memories. If it's too much for you, we can conduct the enquiry at the Security Bureau instead—it might not be as efficient, but it's an option.

No need. Let's just get it over with. Benefit +3
I'm not that fragile. Empathy +3

Response Impression Points
It's okay. Morality +3
I want compensation for emotional damage. Chaos +3
Prompt 3
I understand. Music isn't my strong suit either.

Panicked Fisherman Full Dialogue

I haven't been catching much fish lately, so I stole a couple of Phoxichor canisters to sell... But does that really warrant this many people chasing after me? Officers, please, have mercy! Give me another chance, I beg you...
