Brothers of Thunder

"I won't ever hurt you... Not on purpose anyway. If anyone tries, I'll make sure they'll regret it."

Kaigaku's eyes widened in surprise when he felt Zenitsu lean into his protection and return the hug.

The back of his kimono started to become a little damp as his brother cried into his shoulder. He couldn't bring himself to care.

A strange feeling pulsed in his chest when he realized that he had made Zenitsu feel safe enough to be openly vulnerable. Safe enough to show his emotions without getting hurt for it.

"Thank you... Aniki."

Basically a Good Kaigaku and more intensely traumatized Zenitsu AU.
I'm not sure how far into the actual story line of Demon Slayer this will go, considering I have only watched the anime.
