Kyo-koku (Part 1)

"Isane."

After Aizen and Gin Ichimaru disappeared, Retsu Unohana immediately sent her lieutenant, Isane Kotetsu, to check on the fallen Toshiro Hitsugaya and Momo Hinamori. Unohana instantly appeared at Toshiro's side to check whether he was alive, while Isane, after examining Momo's condition, immediately carried her over to Unohana.

"Minazuki."

As Isane laid Momo beside Toshiro, Unohana drew her Zanpakuto. At her words, the blade immediately transformed into a massive, flat creature with one huge eye at its front. After appearing, the creature lightly nodded to Unohana, then stretched out its long tongue and swept Toshiro and Momo from the ground into its belly.

This was the ability of Retsu Unohana's Zanpakuto. As long as someone was not dead, they could slowly recover within Minazuki's belly.

Before Orihime appeared, this was the strongest healing ability in the Soul Society.

It was a Zanpakuto that suited Retsu Unohana perfectly—she could slash and heal at the same time, enough to frustrate an enemy to death. Especially with her Bankai, its healing ability was even greater.

"Isane, search for Aizen and Gin Ichimaru's whereabouts. Report the information to the entire Gotei 13."

"Yes."

Isane Kotetsu immediately crouched on the ground and used spiritual power to draw a Kidō formation across the floor. The betrayal of two captains, Aizen and Gin Ichimaru, was a major event in the
