Yuba is mentioned as one of the 8 available candidates for Fūjin by Yūichi Jin as the other three either declined or are unable to.

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 2
During the four-way rank war 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 3
On Saturday February 8, Yuba Squad must of fought in the upper group, night division of rank wars as Katori and Ōji Squad's matches were done by the time Tamakoma Second finished and Yuba Squad was ranked 7th but what squads they fought or what their rank was afterwards wasn't shown or said.

Round 4
Since Tamakoma Second fights Ninomiya Squad, Kageura Squad and Azuma Squad in the night division of rank wars 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 wars 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 6
On Saturday February 22, Yuba Squad presumably fights in the middle group.

Round 7
As Katori Squad, Suwa Squad, Kakizaki Squad, and Ebina Squad all fought in the day division, Yuba Squad must of fought against Arafune Squad and Nasu Squad in the night division on march 1st, which gives them enough points to go back up to 7th.

Pre Round 8 meet up
Through Kazuma Satomi, who talks enthusiastically about Yuba's combat prowess to Osamu Mikumo, Shun Midorikawa arranges for Yuba and Yūma Kuga to meet. Yuba has Yukari Obishima introduce herself to Yūma, whom she admires, and when he mistakes her for a boy, Yuba forces him to spar with her as an apology. When Yūma stops holding back and shows off a new technique, Yuba has a round against him and defeats him in an instant with his quick draw.

Round 8 background
as they are back in the Top Group, they are allowed to fight against Ninomiya Squad, Ikoma Squad and Tamakoma Second for their final match.

Fujimaru right before the match starts, his squad is talking about Chika as in the worst case scenario, she would blow everything up with fire power that beats even Ninomiya but it isn't likely to happen as far as they know since she only recently start shooting people so Yuba makes Toonoka keep an eye on her Chika and it will be his sole target as Yuba doesn't need backup and they can't let Chika run free. Yuba talks to Obishima about what she will do if she meets up with Yūma and she replies with how he will have a new strategy prepared and Yuba agrees and praises her. Fujimaru finishes off with how they need to keep their top group ranking or else Kanda will mock them.

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

Yuba along with his current and former teammates met up with Kanda for Dinner to bid him farewell during which he begrudgingly accepts the results of the season but mentions Obishima's growth and claims that the next season might not be so bad which causes Obishima to cry and then Yuba says she should cry to help push herself foward.

Away Mission Test Arc
Yuba is picked to be part of Kuruma's squad #5
