The Couple's World

The Couple's World (二人のセカイ, Futari no Sekai) is the twelfth and final chapter of the School Days manga.

Summary
At the hospital, Taisuke tries to feed Makoto but he refuses, insisting that he can feed himself. Taisuke continues until Hikari stops him, telling him that he would probably just make Makoto feel worse. She insists that Sekai do it instead, causing Nanami to question Sekai's whereabouts. Setsuna tells them that Sekai will be arriving soon, just after she finishes an errand.

Makoto is left to reflect over the incident one week ago. Kotonoha had tried to kill Sekai, but he ended up taking the slash meant for Sekai when he pushed her out of the way. Sekai was shocked beyond words and quickly ran to him before they called the hospital.

Sekai soon arrives and leads the others away so that they can have some alone time. Makoto asks Sekai about Kotonoha before he starts to blame himself for everything spiraling out of control. He promises to take responsibility for all of his mistakes when his phone suddenly starts to ring.

He answers it to respond to a panicked Kokoro tells him that Kotonoha isn't moving and is bleeding out. Makoto panics when he realizes that Sekai killed Kotonoha. She reveals this and tells her that Kotonoha was too dangerous for him, then she insists that she will be the one to bring Makoto "happiness" instead. She goes on to tell him that they should "start over on a clean slate" before she embraces a shocked Makoto.
