Young Fukuzawa Is at a Loss

Armed Detective Agency member, Fukuzawa Yukichi.

As the Agency's combat specialist, his job is usually to stick close to the president who took him in, Edogawa Ranpo, whose deductive abilities are unmatched but who has no combat skills at all, and serve as his loyal bodyguard.

One day, after wrapping up an investigation as usual, Fukuzawa is sent by Ranpo to buy some desserts because Ranpo wants to try a new line of sweets. The moment Fukuzawa steps out of the shop after buying them, he realizes something is off.

Anyone who walks out of a cake shop and suddenly finds themselves in the middle of the road would think something was off, right?

When he realizes he's transmigrated to another world, he stares at the serious, tall, mature-looking version of himself in front of him and is so shocked his eyes practically quake.

Why...

Did I

become the president of the Armed Detective Agency?
