[6][8] Considered one of Stardom's top wrestlers and its "breakout star",[9] Kaischauri is recognized for her unique gimmick, which challenges traditional conventions of joshi puroresu, and for utilizing her diverse background in dance, gymnastics, music, and visual art in her performances.

[13] Since debuting at Stardom, Kaischauri has been ranked annually by Pro Wrestling Illustrated as one of the top female professional wrestlers in the world, most recently placing No.

[17] As a graduate student, Kaischauri's was "highly active in Vienna's DIY and punk scene",[15] which overlapped with the city's underground wrestling subculture.

[26] Kaischauri would perform only sporadically in her native Austria, mostly for WUW and Rings of Europe (RoE) in Vienna, as her career increasingly shifted towards Japan.

In winter 2020, following a six-week tour in Japan, she opted to remain in the country in the wake of the COVID-19 lockdowns, seeing an opportunity to continue advancing her wrestling career in the Japanese market.

[32] Kaischauri described adjusting to the Japanese professional wrestling, which differed significantly from the Viennese underground scene: "In the cellar of the Weberknecht it is hard, damp and dirty.

[34] Thekla returned to Ice Ribbon in 2020 and spent most of the year wrestling in their events; her tenure was focused on defending the WUW Women’s Championship, which she briefly lost to Cherry in July before reclaiming it the following month.

[35] Thekla successfully held the title for the rest of the year, traveling to Austria in September to perform in a few shows for WUW and ROE through October.

Due to the subsequent stoppage of live shows, Thekla trained at Ice Ribbon's dojo on the outskirts of Tokyo; she described the period as "lonely" but "extremely focused" and "the basis for the success I have now."

[40] The match against Fujita would be her last appearance for Ice Ribbon, where she was described as a "big hit" for her distinctively aggressive persona and fighting style, which included engaging in "psychological warfare" against opponents on social media.

[42] On January 3, 2022, Thekla and Mirai were unveiled as the masked assailants and teamed up with Giulia to defeat Cosmic Angels (Tam Nakano, Unagi Sayaka and Mai Sakurai).

[44] At Stardom Nagoya Supreme Fight on January 29, 2022, Thekla defeated Mina Shirakawa for the vacant SWA World Championship, earning her first title at the promotion.

[49][50] She would ultimately take part in the 2024 edition of the event, instead performing in the Blue Stars Block, for which she would receive the 5★Star GP Award for her match against Suzu Suzuki.

[55] In November 2023, Thekla made her first major appearance outside Japan since January 2021, performing in matches in Singapore as part of the three-day Bushiroad Expo Asia 2023, which was co-produced by Stardom and Singaporean promotion Grapplemax.

[58] The next day, just before Stardom's main event at NJPW's January 4 Tokyo Dome Show, Thekla and Mai Sakurai joined Giulia as the latter announced the dissolution of the Donna del Mondo faction.

[59] Following her brief hiatus, Thekla returned to Stardom on April 27, 2024, causing Mina Shirakawa to lose her match again Natsuko Tora, and joining the latter's villainous Oedo Tai faction.

Five days later, during the Stardom Sapporo World Rendezvous, Tora declared the dissolution of Oedo Tai and the birth of the newly created stable, H.A.T.E., featuring herself, Thekla, Saya Kamitani, Momo Watanabe, Konami, Rina and Ruaka.

[65] In parallel to her professional wrestler career, Kaischauri continues to paint, make music, and exhibit her artworks;[66] she used her hiatus from the ring in early 2024 to focus on artistic pursuits.

[68] Kaischauri considers professional wrestling to be a form of creative expression in its own right,[69] stating that "the ring is my canvas and I paint a pretty wild picture".
