"As for gratitude, didn't Aisaka-sensei say, multiple times, you people get a share of the loot profits? I am pretty sure she did. And she outright told you that we don't exactly know everything about Achronos, which is why she sent you for the gem in the first place. If you are going to ignore that she did tell you about the risks- and did you seriously expect there to be only weak Shadows? You saw Izanagi, you saw your opponents, you know full well that isn't true.
The Reaper- I acknowledge we should have warned you, but we were busy trying to assemble the teams and get everyone in. We assumed you had the intelligence to run from the obviously dangerous giant floating reaper thing with giant guns that had a clear aura of death around it in the first place- and it wasn't as Kyousuke didn't warn you before it showed up. His analysis isn't exactly perfect, as you already fully know, but it's better than going in blind.
If you people want to leave, I'm not going to stop you. And yes, I know its stressful. Yes, it bothered me that I'm risking my life in a strange world for something I don't know much about. I know the risks.
But if that's going to stop me from doing something about people dying, then I would have left a long time ago. The door's wide open. I didn't join to feel like a hero and I didn't join because it was safe. I joined to save people- and if that involves doing things that doesn't involve it to try and figure out why we have to do so in the first place, then that's fine with me.
If you're that deadset on it, you two, I'll have her know, and you can forget about Achronos and Persona. you can forget everything. You'll never have to speak to us out of school again.
If you cannot handle that yes, we are a flawed operation and that we make mistakes, then you are free to leave."
Maria crosses her arms, staring at both Yoshida and Karma, waiting for an answer.
