Nagumo, Osaragi, & Shishiba vs Satoru Yotsumura is a battle fought by three Order members against the Ex-order member and now Banished Yotsumura.
Prologue[]
As Nagumo and Shishiba were driving on the highway, discussing how Nagumo had mistakenly left Osaragi behind, they were suddenly attacked by several assassins. After quickly making light work of the attackers and killing them, they were interrupted by the sudden arrival of Yotsumura, who was standing on a car hauler truck.
Battle[]
As they noticed Yotsumura standing on the car hauler truck, he suddenly sliced their car in half using his Bladed Three-Section Staff, forcing both Nagumo and Shishiba to jump out of the vehicle to dodge and land on the truck where Yotsumura stood. Upon landing, Nagumo leaped over a car and drew a pair of double swords, rushing at Yotsumura. In response, Yotsumura attacked with a horizontal slash, which Nagumo dodged, but the strike still sliced the sides of the truck, causing the roof to collapse. As the upper floor fell, Nagumo and Yotsumura exchanged blows in a hand-to-hand fight, until the falling debris came down toward Nagumo, who managed to dodge by jumping backward.

As Nagumo dodged, Shishiba attempted to attack Yotsumura from behind with his hammers. Yotsumura blocked the attack with his weapon, but the brief clash gave Shishiba enough time to recognize Yotsumura's identity. As Shishiba realized who he was, Yotsumura glanced upward, noticing Osaragi descending from above. She broke through the roof of the truck and landed on the hood of a car, smashing it and immediately attacking Yotsumura with her Buzzsaw, which was connected to a wire. Although Yotsumura blocked the attack, it still sliced through the rest of the truck, forcing all the fighters to jump off and land on the road. Seizing the moment, Yotsumura leapt onto a moving car and fled, remarking that facing three Order members at once was too much.
Aftermath[]
As Yotsumura successfully fled, the trio was left in the middle of the road. Noticing that Osaragi had bought a lot of snacks, Nagumo asked if he could have one, but Osaragi bluntly refused and then interrogated Shishiba about why they had left her behind. Shishiba responded by blaming Nagumo.
