Deep Down: Pride

"Is Pride truly a deadly sin? Surely, living without it is much more torture than living with it. I mean, after everything I've been through and everything I've done, I have to accept my pride. I am proud to have run away. I am proud to have fallen in love. I am proud to have lied. To have killed. I am proud to have survived, at least in a way... And I am proud of writing my story to you."

Although thought to have died, Etsuko Nokori wakes up in a hospital months after his drug overdose in a world filled with monsters. He finds a journal in the hospital, where he learns of the world's new residents: Carmuts. The world would've ended already if it hadn't been for humanity's resilience, thanks to a serum, but even humans became monsters themselves. Etsuko, who hated his previous life's people, fell in love with his current ones. He now desires nothing more than for everyone in his current life to live and stay with him.
