The Days I Collected Cards in Yokohama

There's something incredibly addictive about these little dogs.

Matsushima Ayako is either grinding or on her way to grind, yet even so, she still hasn't managed to complete the full collection.

Then one day, she discovers that she's ended up in Yokohama, a place where people have special abilities.

Most importantly! She! Discovers! That she can pick up cards!

But she has to follow the game's rules to clear stages and earn points, or the cards she picks up will be useless. And so...

Ayako: "...Um, could you make me some marbles? Preferably colorful ones, and bigger is better. They should also be easy to break."

A certain boss: "You can work here, and I'll make you as many marbles as you want."

A certain company president: "...There's Ranpo here, and plenty of marbles, too."

[Important]

1. The female lead can appear in the form of the cards she owns. P.S. The abilities and personalities of those forms have an impact, so her appearing as a male character is unavoidable. Proceed with caution if that's not your thing.

2. Probably no romance. The female lead herself doesn't appear often, since she's always using a secret identity. She's a heartless card-collecting machine. Her identities won't be exposed.

3. The author is new and the writing is rough. There may be out-of-character moments, so please be gentle.

4. Some of the card details and settings are based on the Bungo Stray Dogs mobile game.
