|Day 1 This takes place after chapter 1. Satsuki says she doesn't regret losing the challenge and that if she met 31a earlier she would've helped and changed. (note: Satsuki is speaking with a emotional voice something we never hear) Satsuki questions if she's even being useful to 31C. she calls out to her mother for advice.
Everyone in 31A is happy that the holidays have arrived and they head of shopping. Ruka enters a shop and sees Satsuki. Satsuki says she handles most of the shops as there's not much humans left. We enter a music shop and see Satsuki again. Ruka leaves and goes to another shop to see if Satsuki will be there and she is. Satsuki says she has really good movement.
31A meet up. ruka asks if Satsuki was also managing the shops and Yuki says yes. Everyone is now equally confused oh how Satsuki can move. We then get called by Tezuka. She says that a powerful cancer has appeared in Ikabukero where 31C are currently stationed. We need to go there to help. We search the first floor of the dungeon but return as we are all tired. Day 1 complete
The next day we 31A spots 31c arguing. Ivar is arguing with a angry satsuki. Satsuki tells ruka that Yayoi is lost in the ikabukero dungeons they went yesterday. Ivar wants to rescue right away but Satsuki says to wait for the seniors to help. However the seniors are taking too long so 31A decides to help instead. 31C are conflicted to help Ivar as they rather gain help from the seniors which upsets Ivar heavily and she leaves on he own Satsuki and 31A follows
We reach the airfield as see that Ivar has already left. Satsuki says she wants to make sure 31c stays together and make sure they don't fall apart. 31A says they'll help out and even take the blame if caught and Satsuki smiles once again We search the second floor and fight our way through. Everyone's tired by the third floor so Yuki advices everyone to leave for today. At night Satsuki tell ruka that Ivar hasn't come back yet. Ruka then helps Satsuki talk to the members if 31C. The members of 31C feel unexperienced so they think it will be reckless to look for Yayoi. However satsuki says she will act as the commander and help look for them. At the 31A dorm Yuki says that the Seniors will rescue Yayoi and Ruka says she will still go.
Day 3 When they arrive to look for Yayoi and Ivar everyone senses aftershocks. They get louder the closer we get. When we clear the third floor a massive earthquake happens and we get separated Marie is injured in the leg and we can hear Yuki on the other side. Satsuki begins to doubt herself saying that if she let the seiners handle everything no one would be hurt. She begins explaining her backstory.
Satsuki explains that her job family job was to prescribe illegal drugs when asked and from a young age she learnt Ninjutsu (which is also why she can move very fast) However she was the weakest out of her siblings. But because of her training she could move very fast so she took multiple part time jobs to earn money and also done her Underground jobs. However she wasn't needed by her family. To feel needed she joined the Seraph unit.
Suddenly something comes but leaves when Satsuki notices it. Ruka remember that Tezuka told her that a cancer not even 31C can defeat lives around here. if they spot it they need to leave so they retreat. Satsuk puts herself forward to distract the powerful cancer while everyone escapes. 31C gets mad at her however for trying to through await her life like this. They save Yuki from behind the bolder and 31A all arrive. However a cancer appears. We defeat it and continue to look for Yayoi and Ivar. We luckily find them. Ivar says that when they were younger Yayoi used to get lost by following a Cancer that looked like her toy and it happened again now. Ivar stayed with Yayoi in the dark so that the massive cancer we just fought couldn't find them. However she couldn't contact anyone as there was no signal. To keep Yayoi happy Ivar said this was a "trail" she she needed to complete And now that the trail is over they can both now eat and drink.
When we arrive back Tezuka punishes Ruka and Ivar to cleaning the toilets for 2 weeks because leaving to save Yayoi without permission but she also thanks Ruka for saving them
Satsuki says that after this event the bond will increase in 31c improving teamwork. Satsuki mentioned that she has her mothers tablet she found however cant open it however Yuki says she'll unlock it. They go to the shop to find piece to fix it. In the evening Yuki fixes it. When it opens they find her mothers dairy. Satsuki is scared to read it because her mother viewed her with cold eyes and her father only trained her. She believes the dairy wont have anything positive about her. The dairy has been logged since the day Satsuki was born. Inside the dairy praises Satsuki for being a strong intelligent girl. No matter how hard she's beaten she never shows the pain. Her mother wanted her to take over the family business. and to be raised as a normal child. Her mother writes that if she was still here, she will tell her to "do her best" We then Satsuki mother telling her daughter to live a normal life and if she can be her mother again and hold her. Her mother says "thanks for being born Satsuki" and that shes waiting for her wedding day.
Satsuki is shocked about her mother words. Her mother died in a cancer invasion. Satsuki is upset that she never cared for her mothers feelings And promises to her mother that she will take over the family business and be happy.
And the event ends.|
