Merchant Aja is an acquaintance of Yamada who visits the player often, mostly to break the news of an event (aka public debug).

Merchant Aja also appears in the Turtle Bath as Aja (Nude).


Aja is a dark-skinned man believed to be Indian. He wears a turban with a reflective red gem at its front. He also has a black mustache which is similar to Yamada's.

As The Best ProgrammerEdit

When not in Yamada's game, Aja wears a dark grey suit and pants, paired with a white inner shirt, a ruby-colored tie and brown shoes.

Aja sometimes appears with two floating laptops.

As a dungeon merchantEdit

Aja wears a purple robe with a green inner wear.



Aja: Yo Yamada-san! Namaste. I'm Aja. I'm The Best Programmer. Look, Yamada, dude. I don't think you're being very efficient, bro. We gotta step up this operation. The way I see it...Your game lacks two key features. For example! 1. There's not a lot to buy with GOLD. 2. You don't have enough human characters in the dungeons.

Yamada:Hmm. Hmm. First of all! Thanks for your feedback. I'm genuinely flattered that you took an interest. Also, uh. You might be right.

Aja: Well, I'd say--for starters--Put me in the game. I can be the Dungeon Merchant. This will solve both issues at once! How about it, dude?

Implement one of Aja's systems? (He's The Best Programmer)

Let Aja appear in-game

Take a rain check

Aja: Yamada-san! You chose wisely. I can implement this in about... ...five seconds. Please stand back!




Aja: Okay. It's done, dude. Report any bugs ASAP. Feel free to call me anytime weekdays after 7am. Talk to you soon, Yamada. I'm goin' to the gym.

Yamada: Wow, yeah. That guy really is... ... The Best Programmer.

Aja and Yamada-kun implemented "Dungeon Merchant"!

In the dungeons, Aja runs a shop which stocks 3-5 items. These items are notably cheaper than the Item Shop which is accessible in Yamada's apartment.

For more details on his shop's goods, see Aja's Shop.

Stealing from Aja Edit

See Aja's Shop.


  • The skill Trick Ball DX will get reflected off his Magic Barrier, thus morphing the hero into another enemy on the floor.
  • Aja appears in the background of several Dandy Collections, including Aja, Curry Knight, Duck, and Yokozuna sets.
