Chapter 134: New Cero (0) Espada
Szayel Aporro, in the original book, once divided himself into two people, which caused his strength to degenerate and fell from the position of Cero (0) Espada. Needless to say, Starrk who was always lonely because he was too strong, also created Lilynette who was separated from his soul.
This method of soul splitting is certainly rare and not everyone can successfully do it.
But for Mazuru, it is not impossible. You know, his Zanpakuto can imprison the souls of dead enemies. In other words, his Zanpakuto is actually an extremely rare Zanpakuto of the soul system. With the help of the ability after he mastered Bankai, he divided his soul into a part. Although this temporarily reduced his strength a lot, but he will not be like Tokinada, unable to recover. Of course, the speed of recovery is not very fast.
Then, he injected this separated part of his soul into Metastacia's body.
Hollow realizes evolution by devouring its companions. In other words, before it evolves into Menos Grande, there may be countless soul fragments in the hollow's body. Metastacia is just an experimental subject, and his consciousness has always been in a muddled state, so the part of Mazuru's soul easily took over and became the master of its body. Then, with the help of Metastacia's terrifying devouring and fusing abilities, in the forest of Menos Grande, it continued evolving till it became a top class Vasto-Lorde.
Now, with the help of Hōgyoku, he has become an Arrancar.
Inside the enchantment of Mazuru's Bankai.
Mazuru also has subtle emotions. Over the years, they were like two different individuals. Although they are the same person, they were in two different worlds after all, and their souls have been separated, so they cannot know each other's thoughts and experiences. Occasionally, some contacts were also made with the help of Kidō which helped them to communicate.
For the rest of the time, Mazuru did his job as a captain in the Soul Society, and Beelzebub did his job as a Menos Grande in Hueco Mundo.
The two communicated with each other in this space. Beelzebub learned about some changes in Soul Society, Mazuru learned about the changes in Hueco Mundo, and also learned about Sojiro's current state from Beelzebub.
Because Aizen and Gin were still outside, they didn't chat for too long, and then started fighting again.
