Komamura has always hid his appearance from others in the Gotei 13. But when he's forced to reveal himself so Unohana could heal him, his violent past comes to light.

Komamura realizes he wasn't the only one who was betrayed. He sets out to lift up the spirits of those who are suffering just like him. He wants to be like a sturdy wall that's leaned on as support—literally and figuratively. A sequel to "The Heart's Cruelty," but you don't need to read that story in order to enjoy reading this one and understanding it. Reposted from Ao3.

Three captains had betrayed the Gotei 13, Central 46 was massacred, and Kuchiki Rukia's execution was found to be illegitimate. Komamura only felt emptiness as he wondered what he could've done to stop it all.
