Bungo Stray Dogs (light novel)

Doppo Kunikida is an idealist and a straitlaced detective at the Armed Detective Agency, an organization that takes on dangerous jobs even the police won’t handle. Everything in his life is going just as he’s planned…until one day, he’s paired up with the agency’s newest hire: a suspicious, eccentric, suicide-obsessed man named Osamu Dazai. Their first case together turns out to be far more complicated than Kunikida anticipated—and it looks like the detective agency’s sworn enemy, the Port Mafia, is somehow involved, too!

Before he joined the Armed Detective Agency, Osamu Dazai was the youngest-ever executive with the Port Mafia, the most notorious underground crime syndicate in all of Yokohama. Three of its members—Dazai, Odasaku, and Ango—formed a camaraderie despite their vast disparities in rank. When Ango suddenly goes missing, Odasaku, a lowly Mafia grunt, receives direct orders from their boss to find him…only for Ango’s trail to lead Odasaku to a mysterious, foreign criminal organization called Mimic.

Over a decade before the events of the manga series, a chance encounter leads professional bodyguard Yukichi Fukuzawa to begrudgingly take an arrogant boy genius named Ranpo Edogawa under his wing.

The Armed Detective Agency’s latest case brings them to the floating city Standard Island, a strange man-made vessel and a resort for the wealthy off the coast of Yokohama. But what awaits the detectives turns out to be far more complicated than any of them could have expected: a bomb, time travel, a mysterious skill user named H. G. Wells…Will this case spell the end of Yokohama itself?!
