History

Before Girls' Frontline

Mica Team was formed in 2008 by 19-years old animation college freshman Yuzhong, as a doujin circle to produce the visual novel Girl of the Bakehouse which was released in 2009. The circle comprised three people, and Yuzhong dropped out in his second year, preferring to gain experience working on real projects.

While working on more Bakehouse projects, the group also published doujin artbooks: a K-On!/Haruhi Suzumiya crossover, Touhou Modern Warfare, a book dedicated to Touhou's Suwako Moriya and the Guns&Girls series.

The Bakehouse projects eventually led to a partnership with studio GameMaster to develop the strategy game Codename: Bakery Girl, released in 2013.

Girls' Frontline

On 25 October 2015, Mica Team incorporated under the name LBX (used in the earliest marketing only), quickly changed to Sunborn, and announced their mobile game Girls' Frontline. After three beta tests and development troubles, Sunborn launched the game in Mainland China in 2016, in Taiwan, Hong Kong and South Korea in 2017, and in a global English version and in Japan in 2018.

The company was short on cash as it started: employees worked in a rented apartment with folding tables for work desks, and meals were cooked rather than ordered in to save money. There were only 4 employees at the start of the development, but the team had grown to 35 when the game launched in China, then to 117 in 2018 and over 300 in 2020. A Sunborn Japan branch was opened in March 2018 to manage the game in this key market, starting at 20 employees. In March 2020, as the contract ended with Digital Sky, which was Girls' Frontline operator in Mainland China, Sunborn announced that the game's operations were transferred to Darkwinter Software Co., Ltd. (上海暗冬网络科技有限公司), a wholly-owned subsidiary of Sunborn. Darkwinter is listed as Sunborn games distributor in the English-speaking app stores.

Expansion

The commercial success of Girls' Frontline enabled Sunborn to announce a remake of Codename: Bakery Girl in 2019 titled Reverse Collapse: Code Name Bakery, and three Girls' Frontline-related games were announced in 2020: Girls' Frontline 2: Exilium, Project Neural Cloud and Girls' Frontline: Glitch Land. Sunborn's strategy at the time was reportedly to remain in its niche market and rely on internal evaluations rather than compete with high-budget games reactive to market trends, based on the idea that the studio's DNA lied in the “2D + Strategy” niche. Development updates were shared with some regularity through the Beilan Island Shelter Broadcast livestreams, hosted by Yuzhong, Smoke (Executive Producer for Girls' Frontline 2) and Kamie (Executive Producer for Project Neural Cloud) talking through Live2D avatars (very cursed). Girls' Frontline 2 and Reverse Collapse were delayed with no release date due to the Covid pandemic.

Neural Cloud received a first closed beta test in October 2020, then a second closed beta called “Singularity Test” in December 2020.

On 21 April 2021, Tencent gained a 20% stake in Sunborn. According to Yuzhong, the deal involved a 9-figures investment from Tencent and Sunborn would still publish its own games in Mainland China. At the time the studio had more than 450 employees, with about 200 working on Girls' Frontline 2. Yuzhong reportedly retained ownership of Sunborn at 70%. Girls' Frontline 2 received its first closed beta test in July 2021 (CBT-1) and a second (CBT-2) in October 2021. Neural Cloud was released in Mainland China in September 2021.

Development ceased on Glitch Land in early 2022 but progress on Girls' Frontline 2 and Reverse Collapse was shown during Girls' Frontline 6th Anniversary livestream on 14 May 2022. After a Global beta in October 2022, Neural Cloud released in other regions in November 2022.

On 20 May 2022, a recruitment post on Sunborn's HR WeChat group announced positions related to a project called “Project Panda” (代号Panda). Cross-referencing with LinkedIn profiles of Sunborn members pointed to a game within the Wandering Earth IP. Sunborn's involvement in the Wandering Earth Mobile strategy game was announced on 22 January 2023. Mica Team is not included in the announcement. In an August 2023 interview, Yuzhong stated the studio had grown to over 700 employees and teased a yet-unannounced project. Sunborn was one of the speakers of the 9th Inven Games Convention in Seongnam on 13 October 2023, where Yuzhong held a conference on “conveying emotional value through games” and teased the character Klukai. Yuzhong held the same conference at G-STAR 2024 in Seoul on 15 November 2024, where Leva was teased.

On 15 December 2024, Sunborn registered the trademark 少女前线: 回响视界.

Sunborn and the fan community

• Due to the quite long lifetime of Girls' Frontline despite less impressive commercial performances compared to well-known gacha games, Sunborn has acquired the reputation of a studio that doesn't close its live-service games. The fact stands in defiance of CN players regularly calling Sunborn games “pills” (药丸, 丸, or simply 💊, a wordplay on 完, “to end”) or calling “YMFM” (originally 云母飞妈, an insult to the mothers of Mica Team's devs, later reinterpreted to be less offensive) when the games face issues. As of 2025, the only Sunborn live game to have reached end-of-service has been the Mainland Chinese server of Girls' Frontline, which ran without interruption from May 2016 to December 2024 and closed due to legal constraints.
• Yuzhong (also nicknamed 帝国の董事长, from a July 2020 interview in Griffin Daily, and “King Chong” in English) is often the focal point of community in-jokes. The sole Doll of his own design, ^AR 6P626P626P62, is considered his “daughter”. One of her costumes makes reference to a rumor, evolved into a joke, that appeared after the 2019 annual company meeting, claiming that Yuzhong bought a Ferrari car while leaving Sunborn employees without bonus pay. The preview version of the damaged art contained one more reference that was not kept in the in-game version, containing a photograph of Yuzhong on a sickbed, cropped from a 2020 photograph shared on Weibo after he suffered from food poisoning at the time of the Girls' Frontline 4th Anniversary festival.
• In the controversy-hungry Chinese video gaming community, Sunborn as been the subject of a number of so-called “dramas” fueled by social medias such as the NGA forums and Weibo microblog. The most high-profile occurrences involved slander by former employees/contractors Suisai and BSL白龙, and misrepresentation of a partial datamined version of the story of Exotic Cadence. These topics are not expanded upon on IOP Wiki.
• Sunborn games release first for Mainland China before releasing in other regions, which has some consequences:
  • The order in which content is released on these servers doesn't always match the order used on the original CN server. This was particularly noticeable in Project Neural Cloud and Girls' Frontline 2: Exilium. The Global community explains these changes by claiming that Sunborn decides release orders based on dartboard throws.
  • For Girls' Frontline in particular, Global players often rely on guides made by CN and KR players to complete event missions. Confusion over the application of these strategies has led to the saying that “EN can't read”.
• Other topics influenced by the fan community such as nicknames can be found in the trivia sections of ^AR M4A1M4A1M4A1, ^AR FNCFNCFNC, ^HG Five-seveNFive-seveNFive-seveN, ^HG M950AM950AM950A, ^SMG TMPTMPTMP and ^RF M14M14M14.
