I think saya's death in black cat was wrong!!! And I hatttteeee crrrreeed for it v.v HISSSSSSS HAAATTEE that bleepin fuc**** mother fuc**** as***** fuc**** horribly!!! HIISSSSS v.v ahem sorry ^^ yeah I hate creed....
(RANT TIME) He died and worked his culo off just to warn Yukki that his girlfriend is a nutjob, he really did amor Yukki and didn't deserve to have his head violently ripped of his body and for his last words to be "I won't let tu have Yukki." only for those words to be in vain. Oh and Hinita didn't deserve it either, she risked everything to help Yukki too, Neither did Mao who at the end of the día was just a citizen and neither did Kousaka, Yukki deserved that punch!
So what i mean is, Akise and his gang should have lived, and Yukki should have died a horrible death (the guy even had to nerve to sleep with Yuno the siguiente día despite the fact Akise died for him). Akise has to be one of the best lgbt characters EVER.
Minai Ruo from Corpse Princess. Seriously, the Kougun Sect was perfectly capable of keeping her alive por giving her another contracted monk to be her partner (I would say that Ouri should've been her contracted monk, but at the time, he wasn't part of the Kougun Sect, and even if he was, it would've gotten in the way of Makina being his Shikabane Hime, unless he's able to handle having two of them at once), but no! They decided to just let her die for no reason at all! Heartless pricks...
Honestly, Gainax should've taken a cue from Beast Wars and brought back Minai Ruo, albeit as an evil version of herself working for the enemy (just like with Dinobot and Dinobot II).
In a way Yomi's death didn't really further the story of the Ga-Rei series. Ga-Rei: Zero the prologue came after the initial Ga-Rei which still hasn't been animated. I'm not really sure if Ga-Rei: Zero actually has a manga either. But anyway Kagura fights Yomi and kills her and then they skip ahead two years and she's now fighting with/beside Ken-chan (I believe his name is) and he's the main character of Ga-Rei. So the only reason I can think of why they killed Yomi is because she's not in the manga and Ga-Rei was made before Ga-Rei: Zero. Although I think she appears briefly in the manga fighting Kagura but I think that's a flashback of sorts...not really sure I haven't read the manga since I don't like Ken-chan all that much. He's quite boring.
I belive that not killing Yomi wouldn't have done much to the story. Well actually if she was still possessed por the Death Stone then yeah humanity would have been fucked but even her getting possessed didn't do anything for the story in the long run except set the stage for her death. She was a great character and didn't deserve to be killed like that for story purposes. That's not fair to her as a character and it isn't right to make a character just for that reason.
Any character, no matter how small, deserves a meaningful death. Remember that when tu write your stories. The story should shift, however slightly, and it should be acknowledged that they're gone.
