Iris Yabusaki

Iris Tsuna Yabusaki is from Tatsu Village in the Unova region. She's one of Dawn's bullies from Sinnoh Academy.

Background
During her days at Sinnoh Academy, she, Misty, and Ursula were all bullies of Dawn. It was just wordplay at first, but it escalated past that over time. Because of the Tekiyoku, they force Dawn to pay them money to help them pay the Tekiyoku taxes. If she doesn't, they take her somewhere away from others and just assault her. Sometimes, they even beat her up just because they want to, even if she has the money to pay.

Iris and the other two weren't really worried about any other students seeing this, since no one at the academy likes Dawn, but they still beat her up away from open areas. Dawn constantly begged them to stop, but it was to no avail. This usually happens after a day at the academy.

Iris and the other girls also know where Dawn lives (they forced that from her one day) and have threatened to come to her house to beat her up if she tries to escape. Dawn's mom is at work when this happens and usually doesn't come home until around 10pm, by the way, which the girls know.

Present
Iris, along with Misty and Ursula, were all in the middle of another confrontation with Dawn in the first episode. They were by Sinnoh Academy in Jubilife City, which had just dismissed for summer break, and was abandoned for now. The three were demanding more tax money from Dawn. Dawn said that she and her mom have been struggling financially and that she doesn't have it. She begged for mercy, but the three beat her up anyway.

They would continue to beat her up a few more times over the next week, since Dawn still never had the money with each encounter. On July 18th (the day before Dawn's birthday), Iris said they should go ahead and pay their own taxes this time around since the deadline was approaching. However, the girls said they'd beat Dawn up each day until she pays, not counting tomorrow, since it was her birthday. They beat her up again. This was the last time they saw Dawn in Sinnoh, though, since she left the region to travel with Ash and Alain as part of the Mokusetsu, although Dawn did this without letting any of the girls know.

Iris likely knows about this, though, since Ursula has met with the Mokusetsu much later and traveled with them through Sinnoh while they were there for Plates. Before Ursula left, she mentioned to Dawn that she would let Iris and Misty know that Dawn is with the Mokusetsu and that Ursula finally saw her again. They want all the tax money from Dawn that she missed when she left Sinnoh.

Personality
Iris seems to be the most level-headed of the three. There isn't much to show to support this, but she did suggest to Misty that maybe they should go ahead and pay their own taxes to the Tekiyoku after repeated instances of Dawn not having any money to pay them. Misty quickly rejected the idea and insisted on beating up Dawn more until she paid them. They clearly had to end up paying on their own to keep from missing the tax deadline after Dawn left Sinnoh.

Regardless, Iris is still evil since she participates in this abuse of Dawn. It's unknown how she is around others.

Naming

 * Her first name, Iris, is her name in both the Japanese and English versions of the Pokémon anime. There's a plant called Iris. It could also come from flaming dragon iris or the "dragon drums" (tall bearded iris) (also a plant).
 * Her middle name, Tsuna, was randomly selected from a Japanese name generator.
 * Her last name, Yabusaki, is the actual surname of her Japanese voice actress, Aoi Yūki. Yūki is what she changed the surname of her stage name to after becoming affiliated with Breath in 2007.

General

 * Her birthday, September 23rd, is the same date as NegaiShipping Day.
 * Tatsu Village is not the name of the village she's from in the Pokémon anime. It's really called the Village of Dragons, but Nocturnal Jay changed the name. One of the translations for "tatsu" is "dragon" or "sign of the dragon".
