Adalyn Agreste is a DigiDestined partnered with Kudamon and the bearer of the Crest of Trust. She is 13-years-old and she is the love interest of Yamato "Matt" Ishida. She is the daughter of famous Fashion Designer Natalie Agreste and the granddaughter of Renée Agreste.
Adalyn is a young preteen with shoulder-length chestnut brown hair with golden highlights and gray eyes. Because of her looks she is often confused to be Seina Tsumura.
Adalyn is a quiet girl - most of the time - but has recently gone rebellious due to her overbearing and controlling mother - hence why she has purple streaks. Mostly she is a girl who wants to have fun and make friends, but she can't trust many people as they just want to be friends with her just because she's a model. Adalyn has a really bad relationship with her mother and doesn't like to be known as "Natalie's Daughter", "Ms. Agreste's Daughter".
- Hacking: Adalyn is on the intermediate level of hacking. She doesn't do it often, but can use it for her help.
