For some reason SHIELD believes that Keigo actually knows what he's doing. Which says more about the organization than himself, honestly. But Keigo is nothing if not adaptable. He survives Mizuho on a daily basis; this should be a cake-walk. Red velvet, marble frosting and all. Or you know... not that. Sequel to Hook (formerly known as Agent 147) and more frequently updated on AO3.

In which Ichigo is off to save the world again and Keigo is left to babysit two Espadas withing nothing more than a paperclip and some chutzpah. Also they're hot, so that sucks.

Ichigo and co. go to Hueco Mundo to save Orihime. And since Keigo kind-of-sort-of knows about the whole Shinigami shebang, he's suddenly being stalked by jackbooted thugs in suits. And then accidentally gets recruited by them. ((Bleach/MCU) Formerly called Agent 147)
