Chapter 615

At this moment, Yamamoto's burden and Hyousube Ichibei also noticed the arrival of Ishugar's group.

Looking at Ishugar's group, an obvious trace of displeasure appeared on Hyousube Ichibei's face.

"Yamamoto, your subordinates really aren't afraid of death — they dare to get involved in a battle of this level. Still, it's fortunate that I'm here, otherwise they'd surely be dead."

As he spoke, Hyousube Ichibei took out the writing brush that had at some unknown point appeared behind his back, and wrote a single character meaning 'shield' toward the few people of Ishugar, after which he took no further action.

This is one of Hyousube Ichibei's abilities — or rather, one of the abilities of Hyousube Ichibei's Zanpakuto. In its writing-brush state, Hyousube Ichibei's Zanpakuto can cast Kidou-like spells in the form of brushstrokes.

This is also why Hyousube Ichibei normally carries a giant writing brush on his back — because the brush's true form is not a brush at all, but a genuine Zanpakuto.

Or rather, a super Zanpakuto that surpasses every existing Zanpakuto, named Ichimonji.

Watching what Hyousube Ichibei had done, a strange expression appeared on Aizen's face, as if he had only just learned that Hyousube Ichibei's Zanpakuto was actually the writing brush on his back.

And Aestalos, watching the ability Hyousube Ichibei had used, also wore a trace of wariness on his face. After all, when Hyousube Ichibei wasn't using Ichimonji, the aura on his body was, in Aestalos's eyes, no different from an ordinary person's.

But once Hyousube Ichibei began using Ichimonji, he could sense from Hyousube Ichibei's body a Reiatsu no weaker than Yamamoto's burden's.

A Reiatsu of this level — even Aizen, who was cooperating with him, did not possess it. And facing opponents each wielding such tremendous Reiatsu, even Aestalos could not guarantee that he would certainly emerge victorious.

Therefore, upon seeing Hyousube Ichibei helping Ishugar's group, Aestalos had already begun to act.

Immense power, as if about to destroy this very space, struck directly toward Hyousube Ichibei's body. Hyousube Ichibei, meanwhile, watched Aestalos's movements with curiosity, wanting to figure out exactly what Aestalos had done to possess such terrifying physical strength.

After all, even the strongest Hollow could not possibly unleash such tremendous power through physical strength alone.

So Hyousube Ichibei was now extremely curious to see just how far Aestalos could go.

"Thousand-Li Heaven-Soaring Palm!"

But facing that somewhat terrifying force of shattering space, Hyousube Ichibei did not dare be careless, and immediately unleashed a technique.

Although this technique used only spiritual power as its material — an enormous palm-strike unleashed with it — for Hyousube Ichibei, it was enough.

After all, only a palm-strike of this caliber could let him understand just how powerful Aestalos's strength truly was.

On the other side, seeing that Aestalos had already begun fighting Hyousube Ichibei, Yamamoto's burden was not in any rush. Instead, he watched Aizen with perfect calm and asked that question once again.

"Aizen, I'll ask one more time — have you decided to completely betray our Gotei 13? If you still have a heart for repentance, I might only imprison you somewhere......."

"Captain-General Yamamoto is joking. I have never betrayed you — I simply never joined you in the first place. Just like those humans, I have never once regarded you as my comrades."

Looking at Aizen's appearance, Yamamoto's burden sighed, his words full of lament over the defection of a genius like Aizen.

"Since that's the case, I cannot hold back either. I truly hope you're only playing around — that way I could still grant you a quick end."

As he spoke, the space around Yamamoto's burden suddenly began twisting continuously, as if something exceedingly scorching had begun melting the space around him.

"Bankai — Ryujin Jakka!"

This is Yamamoto's burden's true ability — the Bankai of Genryūsai's burden's Zanpakuto, Ryujin Jakka.

Ryujin Jakka itself, as the strongest of the Hell-type Zanpakuto and also the most ancient Zanpakuto, possesses merely in its Shikai the ability to burn half the world. But now, after the Zanpakuto's Shikai, Ryujin Jakka's edge vanishes outright, replaced by a hidden killing intent.

And the Ryujin Jakka, which originally looked no different from a walking cane, has now taken on the form of an ancient tachi, appearing extremely sharp.

"So this is your Bankai — truly terrifying power, Captain-General."

Looking at the seemingly unremarkable Ryujin Jakka, hesitation appeared on Aizen's face for the first time. After all, the Reiatsu emanating from Ryujin Jakka now was enough to make even the present Aizen feel a chill in his heart.
