"Though Bankai is necessary condition to become a captain of Gotei 13. But in fact, there are many people in the Soul Society who have mastered Bankai but have not become a captain."
"First of all, you should be familiar with Sasakibe Chojiro, the vice-captain of the First Division."
Mazuru asked Toshiro.
Toshiro nodded, Chojiro is said to be the oldest vice-captain of the Soul Society, of course he knows about him, but this vice-captain does not seem to be very strong, Toshiro does not understand why Mazuru suddenly mentioned this.
"Don't judge Vice-Captain Sasakibe just by his outer appearance. Back then, he managed to learn Bankai in just one month."
(T.L Note: Maybe the author has forgotten that he introduced mc as someone who has not watched TYBW and only knows some information due to social media. So let's assume that he knows this fact also through social media, or it might be from the memories he got from Tokinada who browsed the Secret Spirit Book Gallery)
Toshiro's heart skipped a beat.
"Sasakibe vice-captain has also mastered Bankai?"
"Then he..."
What Toshiro wants to ask is, since he has mastered Bankai, why doesn't he become a captain, but resigns himself to the position of a vice-captain.
Mazuru knew what Toshiro wanted to ask, and responded before Toshiro could ask, "Maybe it's because he wants to follow the head-captain rather than be a captain himself."
Without saying anything more about Chojiro, Mazuru mentioned another person.
"Back then, the Kuchiki family had a son-in-law named Kuchiki Koga, who later became a criminal for some reasons, but still his talent is undeniable. He had successfully learned Bankai during his student years in Shinō Academy, and because of this, he was chosen as the son-in-law of the Kuchiki family by the former head of the Kuchiki family, Kuchiki Ginrei-san."
Because of his young age (according to shinigamis), Toshiro didn't knew about these past events. So after hearing Mazuru mentioning these, he couldn't help being surprised.
"He learned Bankai during his student years, how is that possible..?"
During the six years curriculum of the Shinō Academy, some shinigami do not even awaken their Zanpakuto, but he had already learned Bankai, no wonder he was favored by the Kuchiki family. Toshiro couldn't help but think of Kuchiki Rukia, who was in the same batch as Momo. She was favored by Kuchiki Byakuya, the current head of the Kuchiki family.
'Did she also got adopted because of some kind of unique talent?'
"Besides, I also know a person who mastered Bankai in only three days, and it's not an unstable Bankai like you."
"Three days?!" Toshiro took a deep breath, "Thats impossible..."
However, after seeing Mazuru's serious expression, he had no choice but to believe in it.
'This is too outrageous.'
Originally, Chojiro learned Bankai in a month and Koga learned Bankai during his student years, these are already outrageous enough, but someone actually not only learned it in only three days but also completely mastered it.
"Who is that man?"
Toshiro couldn't help asking, people like this shouldn't be unknown.
"His name is Urahara Kisuke."
"Urahara Kisuke?" After all, Toshiro is young, so he is still a little unfamiliar with this name.
The name Urahara Kisuke has gradually become a taboo in the Soul Society, many young shinigami have never heard of him, and for some reason, those shinigami who know Kisuke rarely mention him.
"He is the former captain of the Twelfth Division and the founder of the Research and Development Institute. For some reason, he also became a traitor of the Soul Society."
Mazuru introduced Kisuke briefly.
Toshiro's expression also became a little weird.
'Of the three people mentioned by sensei, two are criminals...'
'Or, is it precisely because they are so talented that they have some thoughts that they shouldn't have and became criminals...'
Toshiro's mood became very complicated. After hearing several examples from his teacher, he doesn't dare to be complacent any more. Even though he learned Bankai very fast, it is not stable after all. Moreover, the speed at which he trained Bankai, in terms of time-spent and control, cannot be compared with these people.
Afterwards, Mazuru mentioned some more people.
For example, Kyoraku Shunsui, the first captain who graduated from Shino Spiritual Academy, Ukitake Jushiro who became a captain just after Kyoraku Shunsui, etc...
Anyway, Toshiro understood that his speed of learning Bankai is not as fast as he thought.
Toshiro listened quietly to Mazuru, and thought of another question which he couldn't help asking Mazuru, "Sensei, how long did it take you to learn Bankai?"
Mazuru was stunned, glanced at Toshiro, and responded, "If you count from the time I mastered shikai, it took a lot of years, but if you count from the beginning of formally learning Bankai, it was one day."
"Of course, I learned Bankai by accident."
Toshiro subconsciously ignored the latter sentence, and only heard Mazuru say that he learned Bankai one day.
He doesn't understand what kind of accident can help someone learn Banaki, maybe his teacher is just teasing him by appearing to be humble in contrast to Toshiro's previous complacent attitude. But even if it was a coincidence, he learned Bankai in one day.
'No wonder sensei didn't careed about my initial mastery of Bankai.'
Toshiro understood Mazuru's reason for the lack of interest in his Bankai's learning speed.
"I answered your question, let's continue training." Mazuru changed the subject and brought up their real agenda.
Toshiro was stunned, 'Sensei, this is too much, my Bankai got forcibly released due to high consumption of reiatsu otherwise I wouldn't have asked you these questions to spend time.'
It is precisely because his own state is no longer enough to support a battle that Toshiro asked these questions.
'If I still have the strength to fight, why would I ask so many questions instead of training?'
Mazuru didn't say much, just waved his hand, the sea of blood on the ground surged, and then wrapped Toshiro.
Toshiro's complexion changed slightly, and he immediately noticed the change in his body.
His reiatsu started recovering rapidly.
"Stop getting dumbfounded at everything, let's get started."
Mazuru said to Toshiro who had recovered.
Toshiro came back to his senses, and he gradually realized another reason why his teacher used Bankai from the beginning of the battle. In this enchantment, in addition to blocking the aftermath of the battle from affecting the outside world, it can also help him recover quickly.
"Bankai——"
"Daiguren Hyōrinmaru!"
Toshiro unleashed his Bankai again, and then launched an offensive towards Mazuru.
Holding a blood-red long sword, Mazuru started training Toshiro again.
