Little before the fight between Nnoitora and the girls, Yhwach took the chance when the protective barriers of the Soul King Palace were weakened because Ichigo descended from it, and entered the Soul King Palace.
As Yhwach enters the Palace alongside Jugram Haschwalth, his most trusted aide, his other half, and Uryu, his successor, Jugram summoned several regular soldiers named Soldat to invade the Soul King Palace.
But they were stopped by the arrival of one of the members of 0 division, Tenjiro Kirinji, Hot Spring Demon.
Tenjirl Kirinji is a lean-built tall man with black hair that arranged into an outlandishly large pompadour. He wears a waist-length white jacket that leaves most of his chest exposed, black hakama, a large yellow sash around his waist, and a wooden sandal. His Zanpakuto while in sealed form is a small blade curved tip attached to a long wooden pole.
Kirinji appears and defeats Soldat with his sealed Zanpakuto and taunts Yhwach by stating they don't allow uninvited guests and tells Yhwach he can defeat him before calling out his hot spring waters.
Yhwach demands to know if Kirinji really thinks he can defeat him which Kirinji confirmed and engulfing those present in his hot spring water.
After explaining the water's properties, Kirinji releases his Zanpakuto and attacks Yhwach.
Kirinji's attacks all miss Yhwach despite the latter not dodging them.
Yhwach walks away from Kirinji only to be confronted by Senjumaru Shutara, who says it has been a long time.
Senjumaru Shutara is another member of 0 Division and holds the title 'Great Weave Guard'. Senjumaru has the appearance of a slender and very youthful woman with fair skin and long, black hair that is adorned at the back by a large golden ornament in the shape of a crescent moon with numerous small lines radiating outwards. She wears the standard Shinigami uniform beneath a white long-sleeved haori, over which she dons a further white robe fastened at the front near the center of her chest. She also wears a pair of extremely thick-soled okobo. She has 6 long, golden skeletal artificial arms attached to her back.
She orders her soldiers to attack as Yhwach tries to pass her, but is shocked to see that they were unable to land a single blow before watching as an unknown Quincy emerges from Yhwach's shadow.
The Quincy is the Sternritter W, the Wind, Nianzol Weizol. Nianzol is a young man with gold-colored eyes, long, shaggy black hair, and two tongues. He wears a white, double-breasted, collarless trenchcoat which has two openings for his arms. The lower part of the coat is decorated with four four-pointed star-like patterns. He is also barefoot.
Nianzol explains how all attack is useless against him because he can deflect any attack he sees.
Senjumaru surmises that he can only deflect attacks in his line of sight before having more of her guards appear from behind tapestries resembling the pillars and attack Nianzol from behind. However, Nianzol bends their swords and explains how he can deflect the attacks of anyone whose abilities he has seen before cutting the guards in half. Unfazed by this, Senjumaru points out how she never said that the guards were the only ones attacking before revealing that she has completely replaced Nianzol's outfit with one of her own design. When Nianzol states this is impossible, Senjumaru states that she does not have her name for no reason before warning Nianzol against taking it off before he dies as he is impaled by dozens of spikes from within.
After Nianzol is killed by Senjumaru, Yhwach watches as she summons more soldiers and claims that he can now be harmed. Countering this, Yhwach summons several Soldat from his shadow to combat Senjumaru's soldiers. He then calls on his Schutzstaffel - Gerard Valkyrie, Lille Barro, Pernida Parnkgjas, and Askin Nakk Le Vaar - to take on the Royal Guard.
Gerard is a tall and broad muscular man with light blonde, shoulder-length hair, and pupil-less eyes. He wears a winged helmet and a white cloak fastened at the front with three buttons and a dark red Hagal rune on the left-hand side. He is the Sternritter M, the Miracle who was killed by Nova twice.
Lillie Barro is the leader of Schutzstaffel. Lille is a dark-skinned young man with short white hair and a black mark shaped like a crosshair over his left eye, which is constantly shut. He is the Sternritter X, the X-Axis.
Pernida Parnkgjas wears a long white cloak fastened at the front with three buttons and with a dark red Hagal rune on its side. The cloak obscures its face with shadow, leaving glowing eyes. Perninda is the Sternritter C, the Compulsory.
The last one was the newest member of Schutzstaffel, Askin Name Le Vaar. Askin has medium length black hair with white streaks, with a strand hanging down in front of his face, reaching his mouth. In addition to his Sternritter uniform, he wears baggy pants with the cuffs tucked in his boots, 3 layers of collared silver armor around his neck, shins, and crotch accented with periwinkle stripes with an indigo jewel in the center, as well as ornamental pink, purple, and red bracers on his left arm. He has lavender eyes, a thin face with pronounced cheekbones, and markings running from the ends of his eyebrows to the corners of his eyes. He was the Sternritter D, the Deathdealing.
Upon the arrival, Lillie Barro quickly disposes of Senjumaru by shooting in her head with his gun.
To do this they believed she was dead but in truth Senjumaru, they were fighting wasn't the real one but the fake one as real Senjumaru appears behind them explaining they weren't in the Soul King Palace.
Suddenly, many wooden pillars ascended from the bottom, creating a cage that prisoned Yhwach and his subordinates.
Lillie tries to shot the pillars but to no avail.
Then the creator of the cage, another member of the 0 division explains about the cage.
The member is a plump, purple-haired lady with styled swirl-shaped markings on her cheeks and black lips. She has a large silver adornment in her hair and wears the standard Shinigami uniform beneath a white, long-sleeved haori decorated with the Royal Guard's emblem. Her name is Kirio Hirifune who holds the title ' Ruler of Grain.'.
Quincies hadn't had time to think about how to get out of the cage as another member of the 0th Division arrives.
A newcomer is a dark-skinned man with thick, black hair that is shaven and dyed green on the sides of his head. He wears a variation of the Shinigami shihakusho, featuring instead a green undergarment, and a shortened hakama that exposes his lower legs. Worn over this is a white, sleeveless puffer jacket that bears the Royal Guard emblem on its back, as well as the alternating circle and diamond pattern of a captain's haori along the bottom. His attire is completed by gold-framed sunglasses with blue lenses, and a pair of green slippers that are gold-trimmed and have a shoe-like appearance. He is Oetsu Nimaiya the one who holds the title 'God of the Sword'.
Upon arrival, Nimaiya defeats every single enemy other than Askin with a single strike. Even though wasn't able to kill Askin with a single strike, he still defeats him with th little help from Kirinji.
But this didn't matter that much to Yhwach as he used the lives of those who he deems to be useless and revived his elite force without a single trace of injury.
Lillie who got revived killed Nimaiya with a single shot from his gun even though Kirinji and Hirifune and explained to them his gun doesn't fire a bullet but pierce through anything on its way.
Thus Yhwach makes his way to the real Soul King Palace, leaving his subordinates behind to take care of the remaining members of the 0th Division which they did so.
