On October 20, 2022, the Azur Lane English Twitter account unveiled HMS Janus, a Super Rare J-class destroyer from the Royal Navy, poised to join commanders' fleets via limited-time construction.

        The stunning artwork by Kino Hina portrays the blue-haired, cyan-eyed shipgirl as an angelic figure in a lavish white frilly gown accented with blue ribbons and red details, gracefully wielding an ornate staff amidst swirling white doves and subtle Royal Navy rigging. Her stats highlight strengths in Torpedo (A) and Evasion (A), with chibi expressions capturing her shy, endearing charm against a heavenly backdrop of clouds and faint ship silhouettes. Fans recognized her immediately from prior NPC appearances in events like Pledge of the Radiant Court, building massive hype for her playable debut. This reveal teased her role in the upcoming "Fight On, Royal Maids! (Part 3)" event, promising fresh Royal Navy synergy.

        The announcement racked up over 5,000 likes and 100 replies within hours, with commanders erupting in joy at her transition from beloved NPC to fleet mainstay. "Didn't expect my favorite NPC to become playable so soon! What a blessed surprise," one fan gushed, praising her "fancy yet cute" design and frilly dress. "Holy shit we’re getting her now?" captured the shock and delight of many, while another celebrated completing their SSR J-class collection: "Oh yes please, need to complete my SSR J-Class DD collection." Playful jokes abounded, like "The J is silent, right?" nodding to her name's pronunciation. OW O faces and crowns flooded replies, affirming her "approved" status as the ultimate angel waifu.

        Janus quickly became a staple in the Royal Maids event, delivering strong vanguard performance with her healing utility and thematic ties to sister Jervis. Her immediate Live2D skin, "Fright-Night Scaredy-Cat," amplified her popularity with adorable Halloween antics, previewed soon after launch. Commanders hailed her as a "goddess" for fleet diversity and cuteness overload, sparking fanart waves and J-class memes. The reveal exemplified Azur Lane's knack for elevating fan-favorite NPCs into meta-relevant stars. Today, Janus remains a dock darling, embodying the game's blend of historical nods and whimsical charm.
