It is very sad that krul dead without having any kind of special and unique and glorious moments of hers just like how other side characters like kureto or shinya had for themselves. Krul's personality and character was very well written and had so much potential but it was completely wasted thankful of takaya only focusing on two characters and their relationship for YEARS and completely ignoring all his other side characters aside that now it was time to remove them, which the removal itself wasn't bad or bad writing, it suddenly felt a too rush in forward although it was not and krul's death in all aspects was completely predictable just like how the title of the previous chapter "Queen's time" was a promising title telling us that krul's end is very close, but yep it felt bad and out of blue because unfortunately takaya never gave her enough screen times of her that now she had removed we can't accept it and get over with it, like krul never had any special plans of her and all she did was following mahiru's or ashera's plan and words but she, herself, never had a motivation forward although she was even older than ferid and she literally did nothing all these long times to make a plan of herself to defeat the first or gain more information although we can see how MALE characters like kureto, saito, ferid, ashera, noya and guren had their own plans in their own ways yes a character like crowley had non too but at least we have goddammit novels of him and we got enough screen times of him so that his death didn't felt too rushed or anything but for krul? Nothing. We had nothing. And the sad part is that she was an important side characters not a minor character like chess, horn, rene, lacus, byakkomaro, raimeki and etc. so that if she would remove from the story we won't feel that much of a problem with it, yes she was a side character but she was an important side character, she wasn't anything near a minor side character but unfortunately takaya showed again he is definitely too bad at writing not the side characters themselves but also FEMALE characters so badly too, like krul even in the story of her and her brother wasn't the main one and it was always ashera who was the main character in their stories and krul was playing role of a supporting character even there and it was no single motivation and act from her side throughout the whole manga although we expected so much more and high of her why? Because at the beginning of the manga it was shown that she kind of have plans for both Yu and Mika and she whispered some amazing and mysterious things to Mika and it made us be so curious over it just to realize that no it was never anything important and there were no actual and amazing plan from her side but the amazing plans was only from the male characters or mahiru and that is what made her death unbearable although it was a need for the story and it was simply her time to go away but because she laced character development a lot, her death felt so out of blue.
