u/Sakura_Ankoku:
All of your spoilers intrigued me enough to read it. I would highly recommend just using Translate on the web novel for anyone who was liking it, the plot twists never stop coming.
So some added details and corrections from the last three paragraphs, since some things were missed due to you skipping them (I thought this was the best part of the story too).
!So after banishing Azelea, Raquel ends up time looping Re:Zero style trying to get a perfect outcome, but the sister thwarts her at every turn using what is referred to as \[Reincarnation Time Leap\] which allows her to reincarnate as anyone in any time period (no males have been chosen but the characters consider it a possibility), she only retains memories from her last life though, while Raquel slowly accumulates knowledge. !<
!There's a loop where the sister is childhood friends with Jack, Phil wasn't part of the picture, but everyone survived, the evil god that destroyed the world in a previous loop was sealed long ago and the sister, a new girl named Sara this time, was a descendent of the ones who sealed it, giving her control of it (in this loop only). It was a world everyone could be happy, (yes Jack accepted the sister but didn't know it was her, she was just his childhood friend here) but Raquel couldn't accept because she realized she was jealous, that she wanted to be the one to marry him, which lead to her getting her memories back. It was the last world Raquel time leapt from and it was so different from the current world that "overwriting the save state" of the world that much destroyed her ability to do it any longer.!<
!Raquel was Kyoya's childhood friend, her real name was Asari. She started dating Kyoya when they graduated school, he and his sister mysteriously disappeared a few days later. She just thought she got ghosted after their parents died in a tragic accident and the siblings moved away. She wound up getting involved with a detective who contacted her 5 years later about the disappearances of people acquainted with the siblings. With the detectives help she was directly involved in helping Kyoya escape, at the cost of her own life as the sister caught her and stabbed her to death. Basically this is the event that leads to all 3 of them dying and reincarnating.!<
!Asari makes a deal with the same Goddess to reincarnate behind the other two, realizing she loved Kyoya this whole time, and wanting to save him from his sister. The Goddess says the sister's love was real even if misguided and that's why she was allowed to reincarnate and given power, and that Asari must prove her devotion is equal or greater. She's given the condition she must reincarnate at least 100 years before Jack, and that she will lose her previous life's memories. She's guaranteed to be able to meet him again some day and the test is if she'll fall in love with him all over again. Which of course she does which is how she regains these memories after fulfilling the condition.!<
!With her memories back she goes to confront Jack as the demon lord. Because Jack is still lost in distrust, when Raquel reveals she's Asari he just thinks it's the sister messing with him again. As Jack gets angry and starts saying he'll kill her, one of the only spirits whose power she doesn't have appears, Asmodeus the spirit of Love whose aspect is \[Fate\]. Also the sister's name is revealed as Sara at this time, the same as from that final world, Asmodeus is the spirit she is the Roost of (of course its the Love spirit). Her power is to make love come true. Turns out the goddess reincarnating Sara again and again was Asmodeus, using her power to help Sara achieve love by removing blood relation from the equation through reincarnation. She was actually already with Sara in Japan and her power is how Sara managed to evade police for so long. Raquel copies it using Shaxx, and thus uses her own love to defeat Asmodeus and reach Jack (with some help from Jack's subordinates she won over). Reincarnated people can't be reincarnated by Sara's power as well, protecting Raquel from Sara's reincarnation possession, making her "the one person he can trust". By kissing him, she uses the memory power the twins from the childhood arc use to share her memories with him of all of her time loops she went through, all for his sake, and the regaining of her Earth memories. This pulls him out of his despair and he resolves to go back to what child Jack wanted, to protect those he loved.!<
!They finally bang, and spend some time together in the memory world again going over events and realizing a lot of lore and plot. They conclude that Sara must have 2 forms, the one she's reincarnating as and another one feeding that one information. #1 Spirit Baal is an evil god. It was sealed by 4 heroes. The 3 nations are founded by 3 of them, 4th is a lost tribe Jack is descended from. Lost tribe has seance abilities, one of Jacks subordinates Samijina has seance ability, he's been using her to try and contact Phil's soul to no avail. Turns out Samijina is his long lost little sister of this world, Sara in the spirit world has been using her by pretending to be her friend as a spirit, to communicate to her physical world incarnations through the spirit world, that's how she is getting future info when she reincarnates, she isn't carrying it over, by securing Samijina they prevent Sara from being able to time leap with her deaths, stopping her from predicting their every move. Baal and Asmodeus show up under the control of Sara and kidnap Samijina right as they go talk to her.!<
!They go reunite with the childhood friends, and as they start to form a plan suddenly Jack is somewhere else with missing memories. Long story short its Evelina's doing and Jack defeats her. Evelina is the leader of one of the 3 nations, it has to do with that world building in the loops, but basically they need all of the nations to work together to stop the #1 spirit Baal from destroying the world. Baal is of course being controlled by Sara, it can't be hurt by spiritual arts, and is a giant spider whose webs nullify them. What Jack meant about "you won all by yourself" was that Evelina was one of the reincarnations of Sara but actually drove her out on her own and saved her own identity, she did this by sealing her memories with her own spirit's power. She thought she grew up in an orphanage but it was actually her own sealed memories of her home in order to protect her parents, so when Sara reincarnated in her Sara gained Evelina's false memories she had already given herself in order to protect her life. She joins Jack and uses her memory power to make Jack the hero who will defeat the evil god per an agreement between the 3 nations, as they only have one month before it destroys the world and don't have time for the politics of it.!<
And that's everything to the most recent chapter that was posted in 2022. The author posted this year about maybe redoing some of the earlier parts and things depend on LN sales, but the story is at 80% right now by word of the author.
