Chapter 255: Arrancar No. 103
In Las Noches, after Mazuru came, he seemed extraordinarily leisurely.
After chatting with Aizen, he started roaming again.
Then, he saw a figure leaving quietly. It seemed that he was preparing to leave the Las Noches. That figure, Mazuru was neither familiar nor unfamiliar with, it was the Sexta (6th) Espada, Grimmjow.
"It seems that there are still many Espada who don't take Aizen's words seriously."
Mazuru thought so, he didn't intend to stop Grimmjow or tell others about his departure.
As for why Grimmjow left Las Noches suddenly, he already knew the reason.
After Ichigo and others left the Forest of Menos Grande, they followed the route pointed by Sojiro all the way, and now they had arrived at the outer area of Las Noches, and they will be inside Las Noches in a short time.
When they were outside the in the vast Hueco Mundo, or in the Forest of Menos Grande, these Espadas did not dare to violate Aizen's order, and took the initiative to trouble Ichigo and others, but when they came to the outer area of the Las Noches, the Espada had a much larger operable measures.
Although Aizen prohibited Espada from actively attacking Ichigo and others, it did not restrict Espada from taking actions due to other reasons.
As Espada, it was reasonable to visit the outer area of Las Noches once in a while.
Then, by chance, Grimmjow would meet Ichigo and others, and Ichigo and others, as shinigami, would launch an attack when they see him, an Espada-rank arrancar, which was also a very normal thing.
