Bleach: Watch Closely, This Is How You Use a Zanpakutō

"Whoa! So this is a Tenshintai?"

"It's just a prototype," Kisuke Urahara replied, holding an unusual-looking doll in his arms as he answered Masatsuki Aozaki's question.

They were in the secret training ground beneath Sōkyoku Hill.

The doll Urahara had brought was a special spiritual tool called a Tenshintai—an instrument designed to forcibly manifest a Zanpakutō's spirit by piercing it with the blade.

"This prototype can only maintain materialization for about half an hour. I'm planning to develop a completed version that should extend the duration to around three days."

"A Tenshintai can only be used a limited number of times, but there will always be some restrictions."

Urahara spoke in a relaxed tone as he carefully placed the Tenshintai on the high platform in front of him.

"This particular Tenshintai was developed using data from Benihime. I've already tested it once."

"Now, Masatsuki, let's try manifesting Banshō Senran and see if we can actually perceive it..."

Masatsuki Aozaki nodded and stepped forward. The moment he did, the Tenshintai began to change.

"Huh?"
