Diego Brando had just been decapitated and blown up from ten meters away one second, then opened his eyes the next to find himself somewhere new.
He couldn't understand the language, had no money, and was covered in suspicious bloodstains.
He didn't even know where he was, what era it was, or what this place was called.
Thinking this, Diego hid in the slums while doing his best to learn Japanese and the basics of the times.
Then one day, a young man in a white coat came looking for him. Under the pretext of "working together," he invited Diego to be a security guard at his clinic.
But Diego never expected that within a single year, the clinic's security guard would end up guarding five buildings.
Main crossover with Bungo Stray Dogs; pairing undecided.
I'll write whatever comes to mind.
Theme: The more cunning people are, the more likely they are to end up in unexpected predicaments.
