Here's everything we know about lead researcher Asta in Honkai: Star Rail, including her Skills, Materials, Traces, and more.

Honkai: Star Rail – Asta

“The lead researcher of Herta Space Station and a lady from a renowned family. She's an astronomer overflowing with curiosity, and excels at managing the disparate staff of the space station.”

Asta is the astronomer and lead researcher of the Herta Space Station. In-game, she is a 4-star Fire character, and her Path is The Harmony. Members in this Path are known for being primarily support characters that buff their team with various buffs. In her case, she increases her Allies' ATK and SPD using her Support Talent and her Ultimate.

She is one of the first characters we meet upon starting the game, and also the first ever character you will get form the Standard Warp (Yes, that first Warp is scripted). Players can get more copies of her by drawing in the Standard and Event Warp banners.

In the English voiceover, she is voiced by Felecia Angelle, who has notably lent her voice to Aoi Asahina of the Danganronpa Series, Kohaku from Dr. Stone, and Mona Megistus from HoYoverse's other game Genshin Impact.

Akasaki Chinatsu provided the voice for Asta's Japanese voice. Akasaki is a known voice actress who also voiced Seong Mi-na from Soulcalibur VI, Alice Nakiri from Food Wars! Shokugeki no Souma.
