Sometime after the events of Acceleration of Suguri, something begins to move around a piece of the spaceship that fell to the Earth in SUGURI.
arrives at a site where someone was seen to be flying in the sky. She notes that her senses seem to be dull in this area and thinks that someone is trying to keep her away. suddenly appears, trying to sucker punch Suguri but Suguri dodges it in time. Suguri recognizes Mira, she saw their profile before, and asks why they are here. Mira says it is annoying that they are repeating what they used to do during the war, but they have to follow orders from their employer, they have to beat up Suguri. Suguri notices that this is actually a mechanical doll that is built to look like Mira, but it contains the memories and personality of the original Mira. Mira says that if they beat up Suguri, then they will be allowed to do whatever they want, so Mira attacks Suguri.
After beating all the reproductions of those who fought during the war, Suguri arrives at the site of the piece of the spaceship, where is waiting for her. Star Breaker welcomes Suguri as the guardian angel of the planet as Suguri is shocked that even Star Breaker was reproduced. Star Breaker introduces herself as a monster that turns planets into dust. Suguri says that Star Breaker is not allowed to exist in this world and Star Breaker agrees, saying that there is nothing to do since there is no war. Star Breaker says that Suguri is born to repair the planet, and she was born to break the planet, they must fight now that they have met each other. They must fight to determine who gets to accomplish their goal. Suguri pities Star Breaker but agrees to fight, stating that Star Breaker is not allowed to be here.
After beating Star Breaker, Suguri enters the spaceship and she meets Sumika, who was expecting Suguri. Sumika reveals herself as part of the ship Suguri destroyed and that she is the mastermind behind all these events. Sumika only recently obtained her body and she wants to avenge Shifu's death. Sumika knows that Suguri is not to blame for Shifu's death but Suguri destroyed the ship, leaving her body unfinished, and since Shifu died, no one was able to finish her body. Sumika had to go through hard times until her body was completed on its own. When her body was finished, she decided to first take out all her stress onto Suguri by creating imitations of the people from the great war and sending them to fight Suguri. Suguri says Sumika has bad taste for sending those people after her and Sumika agrees. Sumika says this would only bother Suguri, so it was a perfect plan for revenge. Suguri asks, if Sumika is happy now and Sumika responds by saying that Suguri did not suffer enough, Suguri needs to go through 80% more suffering. Sumika wants to finish the remaining 80% here and now, and Suguri allows Sumika to try to make her suffer. Suguri states that she wont show any mercy, but Sumika asks Suguri to at least show some mercy, then the two fight.
After beating Sumika, Sumika says she knew Suguri would win, Suguri's system is incredible and is like a backup of the planet. Suguri responds by saying she does not know how she ended up this powerful. Sumika says when Suguri had finished reviving the planet to a certain point, Suguri became more powerful. Suguri is surprised that Sumika knew this much and Sumika states that she has gone through most of the data of the planet. Sumika speculates that perhaps Suguri's limiter was removed because Suguri's system evolved by itself somehow. Suguri says all this doesn't matter and asks Sumika if she is happy now. Sumika says its more like she has given up at this point than happy. Suguri forgives Sumika and asks her to promise not to do anything crazy again. Sumika tells Suguri that Suguri's future will be a hard one because according to her research, human history has reached the halfway point and will not last forever and Suguri says she has noticed this too but even when knowing this and even when everyone is gone, she will continue to stay on the planet. Sumika admits that she can never beat Suguri with her mind and will being this strong. Sumika agrees with Suguri to never do anything crazy again.
