From what I understand, she killed him because he still wanted to die. Throughout the ending, he kept stating that he would be better of dead, and wanted to disappear after doing the one thing he could for the girl he loved. Thus, she killed him at the end, granting his delusion.

What's the point of saving the girl you love if she's just going to kill you afterwards

the only time takumi was begging for death was when shogun had driven him to his limit. After shogun told him that it was only to awaken him, he stopped begging for death. The only time after that was during his fight with norose when he was being torchered.

How does takumi heal himself during the norose fight if it wasn't possible to real-boot away injuries.

I'd still like a better explanation as t why rimi kills takumi evev after he saves her.

What are the other endings? I got the prologue -_-.

If its only possible to real-boot with 2 or more people around, how does anyone explain the fight with takumi and all the seiras.

My favorite part was when Taku finally got the sword since the music and everything made it so awesome, but the most intriguing part, that made me unable to stop, was when Sena's mother ate her baby. I was like holy sh--. I'm disappointed that Taku had a easier time dealing with Suwa than the Seira's. I understand that he felt she's been his only ally since forever but still.. It's amazing how Shogun looks so much less creepy and more noble once you find out his true intentions. I wonder why he has/picked that name (which I can't remember right now) from the haunted hospital story and the other patient. Ayase's smile is creepy and cute at the same time.

I had a bunch of questions but I can't quite remember them all. But here are some:
1. Why did Suwa and Hazuki do the things they did? Were they simply corrupted by the Church, or Noah II's power? Or were their nature like that. I still can't believe Hazuki was Grim though. Where did she find the time to play Ensue with Taku?
2. So what happened to Takumi's parents? And where do they actually live?
3. Who was the original Rimi?

1: Suwa and Hazuki were members of the Church, and porters, giving them the ability to use Noah II's power. If I recall correctly, Takumi, or was it Shogun? explicitly stated that Suwa was being corrupted from having too much power.
2: Probably with where Nanami really lives.
3: Rimi is a self-made delusionary existance. That's why she can relate to Taku so well. Rimi was imprisoned by N.O.Z.O.M.I. for as long as she knows, constantly tortured so she could awaken and they could take her 'CODE' sample. She couldn't take it and made the delusion of suicide, killing off her personality, and a new one was reborn to take its place. This cycle continued on constantly until the original Takumi saved her by showing her the sky and giving her a reason to live. (Coincidentally when she awoke and wasn't needed to be tortured any longer, I believe) This part of the story was explained with the spotlight. Where the spotlight shone showed Rimi and Rimi alone, but outside of it was a mountain of corpses of the past her, and nothing else in the world.

Neutral playthrough. Roof scene, after being questioned about seeing the sword (Y/N), it all seems to lead to me being pushed off and then being told to take the sword. Seira tells me not to, ends with "You don't want to die, right-o?" delusion, where it boots to the Title page regardless. I guess there's a bug in it.
