Having read this one in japanese before, I noticed there's a missed joke in page 2: Where Setsuna says "You are meddling", in the original she actually says "I'm the second party!" (as an answer to vice-president wanting a third party's opinion).
Ahh I see. I apologize. Thank you for letting us know, we're just new in this translation stuffs so I was being careless. I'll try to ask my friend about it.
To those who didn't notice, it says Umi is also terrified, you could see that she's crying, although she's still trying to protect Kotori, so its cute and makes sense to me :3
