Chapter 316: Crusade Against Hueco Mundo
After the previous Aizen defection incident, in order to concentrate more forces for a decisive battle against him, the Hueco Mundo Expeditionary Force was recalled for a time, and the captain of the Expeditionary Force, Shusuke, was able to return to the Soul Society after that, and became the captain of Fifth Division.
It was later proved that this move was correct.
At that time, no one thought that Aizen had been operating in Hueco Mundo for so many years, and even secretly turned so many Menos Grande into arrancars.
If they had not recalled the Expeditionary Force at that time, they would have been without a doubt, killed by Aizen in retaliation of them performing their attacks in Hueco Mundo.
Right now, Yamamoto's proposal to re-organize the Hueco Mundo Expeditionary Force was not a sudden decision, but a decision made after some deliberation.
The Hueco Mundo Expeditionary Force was to be formed now for two reasons.
First, after the war between Hueco Mundo and Soul Society ended, Hueco Mundo side had suffered heavy losses. It should be the right time to crusade against them and eliminate as many forces as possible to prevent Hueco Mundo from recovering.
After all, today's Hueco Mundo was no longer the original Hueco Mundo.
After the Karakura Town battle, the Soul Society had realized that the arrancars of Hueco Mundo have the power to wrestle with the Soul Society's captain-level shinigami, which was something they could not have imagined before.
Although Menos Grande of Vasto-Lorde level had existed in the Hueco Mundo in the past, during the battle between Soul Society and Hueco Mundo in previous years, Soul Society also beheaded Menos Grande of Vasto-Lorde level, such as the dead Seventh Kenpachi, who once accomplished this feat by himself.
So though Vasto-Lordes were said to be very strong, in fact, for the real strong of the Soul Society, that was not the case.
