(Observation Level 1)
It wasn't the most pleasant encounter.
You might say that this would apply to facing any Abnormality in battle, but this one just...felt unusual, somehow.
It was sitting languidly still and crying strange noises, looking like it had given up on everything.
The protruding blue eyeballs were shifting around with no confidence...
Yeah. It was kinda getting on my nerves. I thought I might go crazy if I had to hear its cry any longer.
I would rather just...
→ Is that the reason you swung your mace against the orders? I find it hardly convincing.
→ Nah, I'm with her. I'd snap too if I kept listening to that bloody croak. 'Sides, we're supposed to beat those Abnormalities or whatever until they're eggs, aye? What's the problem here?
→ I, I thought so, too… I agreed it would've been better off to reduce it to an egg quickly…
→ What's clockface on about now. They're ticking an awful lot.
→ …Executive Manager asks for some respect for salvaging you tools after you got yourselves killed in an idiotic charge.

I think I've learned one thing.
I don't know how it came to attack its foes with its own eyeballs, but it looks like getting hit by it drains your energy (on top of it being incredibly gross).
…Does it? Gimme a moment.
Hmm… I asked a few other Sinners about this.
In conclusion… The more times you're hit by its tongue, the deadlier the eyeball seems to be.
I couldn't figure out further details, but I think it's safe to plan our tactics around avoiding its tongue, manager.
Which is good. It did not feel good to get hit.
→ Talk about a weirdo. It's not really tough at all, but it makes me feel all weak and drowsy~
→ Really? I, I felt a little different… Doesn't it make you more gloomy than anything?
→ Huh? How?
→ Like… Past memories popping up, or… Wanting to give up and die…
→ …Um, Faustie? Looks like our kiddie needs some mental aid?

The left eye reduces health, and the right eye damages sanity.
So that's how they worked.
Well... Not like this changes the fact that it's best to avoid both.
In any case, we now know why dragging on doesn't do us any favor.
I felt like I was being dragged deeper into the swamp of gloom as the fight went on.
I suggest we make quick work of it with fast and powerful attacks, manager.
P.S. This just occurred to me...
I wonder what would've happened we just waiting until it's finished crying?
No, I'm not saying we should try it. I don't see it being efficient, either.
It's just... I remember someone doing the same for me a long time ago, and it helped me back then.
