"Although I can't see it, I can vaguely sense that there's something here! The Reishi density in this spot is clearly different from elsewhere! Souya, this must be your Zanpakuto's ability, right?" Yamabuki Chidori stopped teasing him. If she really scared the kid into a mental illness, she wouldn't even have anywhere to cry about it.
Seeing that his unreliable teacher had finally acted reliable for once, Chizome Souya was so moved he nearly cried.
He explained the powers of his Zanpakuto in full, along with Amatsuyu Tsuru's situation.
Amatsuyu Tsuru herself was closer to a spiritual entity, so aside from Chizome Souya, no one could see her.
Only in the future would the young Kisuke Urahara and Shihōin Yoruichi happen to see Amatsuyu Tsuru while researching the Tenshintai.
The Tenshintai was a tool that could materialize a Zanpakuto's Blade Spirit. The Wooden Dummy Kurosaki Ichigo used to train Bankai was a Tenshintai.
With her chatterbox personality, the moment Amatsuyu Tsuru discovered strangers who could see her, she immediately rushed over and openly introduced her abilities to them. She even revealed Chizome Souya's plan. She was truly the pinnacle of screwing over her own master.
Chizome Tsubaki suspiciously looked around, but she did not see anyone else.
"Stop looking. This is one of the Zanpakuto's abilities. No one but its owner can see her!" Yamabuki Chidori no longer wanted to tease the children. "Making her shut up is actually simple. Just release your Bankai!"
Chizome Souya froze, then fiercely slapped his own forehead. He had not thought of something so simple.
In the original story, after Chizome Souya learned Bankai, he remained in Bankai at all times. Under those circumstances, defeating him was almost impossible unless someone could destroy an area as vast as the Seireitei in a single strike.
