Nono Fujimaru/Plot

Background
Fujimaru went to the same school as Haya Kittaka and they became friends. unlike her friend she was unpopular due to her bluntness. At some point she joined Border and became the Operator of Yuba Squad ever since the beginning of the squad.

Introduction Arc
Yuba Squad presumably takes part in the extermination of all rads in Mikado City.

Large-Scale Invasion Arc
Yuba Squad is seemingly not deployed during the Second Large-Scale Invasion, and could, therefore, be among the B-rank Squads with missing members which Masafumi Shinoda prevents from fighting against Aftokrator's forces out of fear of capture.

Round Two
During the four-way rank battle of the day division on February 5, Yuba Squad faces off against Azuma Squad, Katori Squad and Ōji Squad. The three Squads manage to force Haruaki Azuma to bail out by focusing their fire on him.

Round Three
On Saturday February 8, Yuba Squad fights in the night division of rank battles but what squads they fought or what their rank was afterwards wasn't shown or said.

Round Four
Since Tamakoma Second fights Ninomiya Squad, Kageura Squad and Azuma Squad in the night division of rank battles on February 15, and since Katori Squad and all other possible opponents were in the middle tier of B-rank or lower, Yuba Squad must have fought in the day division against Ikoma Squad and Ōji Squad. After the scores from both divisions are tallied, Yuba Squad is shown to being fourth place with 22 points.

Galopoula's Blitz
Azuma Squad, Kageura Squad, and Yuba Squad fight in the night division of rank battles on February 19.

Round Five (Night)
After the results of the night division are tallied, Yuba Squad is overtaken by Tamakoma Second and pushed to eighth place.

Round Six
On Saturday February 22, Yuba Squad presumably fights in the middle group.

Round Seven
On Saturday March 1, Yuba Squad presumably fights in the middle group again.

Round Eight Top Group Match
After Round 7, Yuba Squad rose to 7th which allows them to fight in the top group again in this case against Ninomiya, Ikoma and Tamakoma second

Right before the match starts her squad is talking about Chika as in the worst case scenario, she would blow everything up with fire power beats even Ninomiya but it isn't likely to happen as far as they know since she only recently start shooting people so Tonooka will keep an eye on Chika and no one else and Fujimaru finishes off with how they need to keep their top group ranking or else Kanda will mock them.

Fujimaru as Yuba Squad's operator helps out during the match but notices Tonooka moving about while Yuba and Obishima are trying to beat down Hyuse and then she praises him after Tonooka shot down Chika's meteor.

Fujimaru was shown again during Round 8 helping out Yuba with the distance between him and his opponent then told Yuba, Tsuji's Location which let Yuba dodged Tsuji's kogetsu slash.

then for her final appearance in the round was telling Yuba Squad that Ninomiya squad reunited so Obishima needs to get over there fast before Obishima bails out.

She appears after after the round ends with the rest of her squad where they currently rank 7th but the final middle group match will decide their final rank.

Post Round 8
Nasu gets enough points to reach 7th place which bumps Yuba Squad down to 8th.

fujimaru along with her squad and former teammates get together for a farewell dinner, Fujimaru's predation about Kanda mocking them came true and comforts Obishima after she starts crying.

Expedition Selection Exam Arc
Nono gets assigned as the Operator for Kakizaki's temporary squad.

it was predicted that Kakizaki and Fujimaru would be able to handle kageura's and inukai's fight as well as the ticking time bomb that is taichi.

after the actual exam starts, Taichi and Fujimaru comment on Kakizaki's reasoning for picking the duo (that being that they were both former A-ranks) then Fujimaru tells the boys to not fight.

some time after the first day starts, the first special assignment comes in and Inukai whether accidentally or intentional provoked Kage but Fujimaru shuts it down before it went any farther.

After Fujimaru and her temporary teammates finish their assignments, she gets ready to cook dinner and says that due to her not being a morning person will cover dinner.
