— Donko in Portable DX
She is an anthropomorphic shime daiko taiko drum with a red face.
It depends on her feelings, however, her face can turn cyan.
Most of the time, Donko is very lovely and kind maiden. However, she will immediately become jealous and angry if she sees someone (especially if it's a female) together with Don (who is usually her crush).
In Namco High, her personality is different than what she had in Taiko no Tatsujin series. When the cousin met and asked her about the drum pun, Donko pretends to be rude and jokingly threaten them that she owns the school before quickly reveal that she is just kidding. From the inside, she is a nice person.
It is unknown on how she had a big crush on Don. She later followed the Taiko drum duo into Tokyo. She has since been practicing her shinobue skill in order to participate in the festival.
In Namco High, it was revealed that she dumped Don for unknown reason, and usually refers to Don as her ex-boyfriend.
In the game
Donko usually appears as one of the standard dancers and appears in some mini-games.
Donko confront Don (who had became a bosozoku-inspired delinquent) and the Dokon gang. She tried to tell them to stop making loud noise around the town, but the delinquents didn't listen and make some excuses. This pushed her to the breaking point, as she proceed to punch all four of them out of anger and send them flying into the sky.
Donko visit the Wadaiko Laboratory to meet Don, and as she arrived there, she met Alumi. Don accidentally angered Donko as he said that Alumi is honest and cute. Before Donko can do anything, she was punched by Alumi and is sent far away from the laboratory.
Donko visited Don and co. again at the festival, and reconciled with Alumi, having learned her mistake from the previous encounter.
Donko is one of the unlockable performance characters in the game. Her performance skill allows donders to hit the notes easier.
- "Don-chan you idiot!!" - said the angry and jealous Donko toward Don right before she was punched by Alumi and sent far away.
- "Please accept me!" - said the Giant Donko who chasing Don in the mini game 'Bakusou! Love Love Donko' in Taiko no Tatsujin: Wai Wai Happy! Rokudaime.
- "Excuse me?! Are you giving me ATTITUDE? Do you, like, even KNOW who I AM?! I'm Donko, and I own this school, LOSER!" - said Donko who later turn out to be joking about it toward the cousin on their first meeting.
