Mi Fu is one of the most talked-about NPCs in Arknights: Endfield, serving as a supporting character throughout the Wuling story arc. She holds the rank of Captain of the Wuling Watchguards under the Hongshan Academy of Sciences and reports directly to Zhuang Fangyi, whom she addresses by the formal title of Viceroy. Despite being an NPC in the game's current version, she was teased as a future playable character during the Version 1.0 Release Livestream on January 16, 2026, making her one of the most anticipated additions to the roster.
Quick answer: Mi Fu is currently an NPC in Arknights: Endfield affiliated with the Hongshan faction. No official release date for her playable version has been confirmed, but she was shown among silhouettes of characters planned for 2026.
Mi Fu's Role in the Main Story
Mi Fu's primary narrative function revolves around her complicated relationship with Tangtang and the Qingbo Stockade. She is tasked with chasing down and capturing Tangtang, creating a cat-and-mouse dynamic that drives several story beats in the Wuling region. Interestingly, Perlica observes that Mi Fu never truly commits to taking Tangtang or her gang down for good, suggesting a more nuanced motivation beneath the surface rivalry.
She is also known by two nicknames. Other characters refer to her as Captain Mi, while Tangtang specifically calls her Mimi — a detail that underscores the personal, almost playful nature of their antagonism despite its official framing. Her Japanese name is rendered as ミフ.
Hongshan Faction and Wuling Connection
Mi Fu belongs to the Hongshan faction, one of the major power structures players encounter after leaving Valley IV and arriving in the Wuling region. Hongshan is tied to the Hongshan Academy of Sciences, and its key figures include Zhuang Fangyi at the top, Mi Fu as the military arm's captain, and Tangtang operating as an outlaw on the faction's periphery. This triangle of characters forms the political backbone of Wuling's storyline.
The Wuling Watchguards appear to function as a local security force under Hongshan's authority, and Mi Fu's position as their captain places her in a law-enforcement role within the region. Her direct chain of command to the Viceroy means she operates with significant autonomy in the field.
Mi Fu's Race — Kylin, Qilin, or Something Else?
Mi Fu's exact race has not been officially confirmed in-game, but her visual design has sparked extensive community discussion. She features blunted, chunky horns that resemble those of Lung characters in the Arknights universe, but her fluffy tail is distinctly different from the longer, sometimes fish-like tails typical of Lung individuals like Chen Qianyu.
The prevailing community theory is that Mi Fu belongs to the Kylin race — the Arknights equivalent of the mythological Qilin. In the original Arknights, the operator Leizi is classified as Kylin and shares some design similarities, including draconic horns. However, Mi Fu's bushy tail departs from the horse-like tail Leizi sports, leading some fans to propose she may draw from a related but distinct mythological creature such as the Pixiu or Tianlu. The Tianlu variant is particularly interesting because modern Chinese depictions of it feature the pink, white, and blue color palette visible in Mi Fu's design.
One important distinction players have noted is that Sarkaz horns tend to be sharp and metallic-looking, while Lung and Kylin horns are chunkier and more organic. Mi Fu's horns clearly fall into the latter category, which rules out a Sarkaz classification. Until her playable operator profile is released — which will include her official racial designation — the Kylin theory remains the strongest candidate.
Playable Release Expectations
During the Version 1.0 Release Livestream, the developers showed a New Horizons Trailer that briefly featured Mi Fu. Behind the first teased character, Tangtang, five additional silhouettes were displayed, hinted as characters arriving throughout 2026. One of those silhouettes closely matches Mi Fu's design.
Tangtang was indicated to arrive within the first couple of post-launch updates, but no specific timeline was given for Mi Fu or the other silhouetted characters. She is expected to be a featured limited character in a future version update, though no official banner date or version number has been confirmed. Early community speculation from the official website artwork suggests she may wield a polearm-type weapon, but this remains unverified.
Mi Fu is currently listed alongside Tangtang, Rossi, and Zhuang Fangyi as characters expected to become playable operators at some point during the game's 2026 content roadmap.
How Mi Fu Fits Among Endfield's Cast
Arknights: Endfield launched on January 22, 2026, with a roster of over 20 playable operators spanning six classes: Guard, Defender, Supporter, Caster, Striker, and Vanguard. Each operator is locked to a specific weapon type — Sword, Greatsword, Polearm, Handcannon, or Arts Unit — and an elemental affinity such as Physical, Heat, Cryo, Electric, or Nature.
Mi Fu's class, element, and weapon have not been officially revealed. Her military role as a Watchguard captain could point toward a Guard or Defender classification, but this is purely speculative. What sets her apart narratively is her position as one of the few Hongshan-affiliated characters likely to join the Endfield Industries roster, which could carry interesting story implications given the political tensions between factions in Wuling.
Mi Fu stands out in Arknights: Endfield's cast as a character whose story presence already feels substantial despite her NPC status. Between her layered rivalry with Tangtang, her position within Hongshan's power structure, and the mystery surrounding her exact racial heritage, she has all the ingredients of a compelling future operator. Players eager to add her to their team will need to watch for official announcements as the game's 2026 content updates roll out.
