This world is called "Akatsuki"
"Thirteen, Thirteen, your eyes are staring at me like a ghost. Didn't I just look at Akui a few more times? Don't worry, hey, if you like him, you still like him, and I will still help you grab the seat responsibly~ Well, I have such a high trust-price ratio, I never lie to people, right?"
"Advice. Never anger Thirteen. Never say 'I guess I guess I guess' with Aquibi. Never snatch Eleven's flute. Never say that Shi Ru looks like Xiao Shou. Also, never be complacent in front of me. You kept flipping your pig's mouth as swollen as a sausage. But what a coincidence, you hit a grand slam today. Congratulations. It's too late to admit your mistake now because you are almost dead. "
"What does it matter? You will grow old and so will I. If you die, I will die too. Tell me, what's the difference?"
"So-called friends, I'll drink to you, it's up to you."
"Only now do I see clearly what I lost... I accidentally broke the glass and picked it up with all my heart, but my hands were covered with scars. I didn't have time to cry out for pain. I just stared blankly at the blood-stained eyes."
"I used to believe in this world so much. Now that I think about it, I feel really stupid. Haha, I thought I owned the whole world. I believed so much in the people I loved around me. I still tell myself that they love me more or less. I don't know if it's true."
"... Look. Thirteen. There are many people who want me dead. Whether it's ruthless, cruel, or a monster, that's what I am now... Anyway, Eleven, you're right, I don't want this in this world."
"I will completely repay what I owe you this time. Hehe, I'm not here anyway when I wake up, so you won't be able to hear me even if I say I'm sorry. Ah, in that case, I'd better not say it. The name Ferenelle doesn't seem to be bad at all. Give it to me, thank you."
