Overview

Lost Princess is the flagship theme of Princess Connect! Re:Dive, Cygames' mobile role-playing game set in the fantasy world of Astraea. Performed in-character by the game's three heroines, Pecorine, Kokkoro, and Karyl, the song serves as the opening theme for the game's first story arc and doubles as the ending theme for its fifteenth and final chapter of Part 1, bookending the narrative with the same melody. Composed by veteran anime composer Kouhei Tanaka (One Piece, Sakura Wars, Keroro Gunsou) with lyrics by Shihori and arrangement by Takayuki Negishi, the track captures the warm, adventure-driven camaraderie of the Gourmet Edifice guild. The song's reach extends beyond the mobile game: it was adopted as the opening theme for the Princess Connect! Re:Dive television anime, with the second season notably using the second verse, an uncommon production choice for a late-night broadcast that speaks to the lyrics' narrative depth. On the rhythm-game side, Lost Princess debuted in maimai FiNALE on April 11, 2019 as a ゲーム&バラエティ (Game & Variety) category track, arriving with a Re:MASTER chart on day one, one of the first two songs in its genre to do so alongside Kimi to Boku no Mirai. It launched simultaneously in オンゲキ PLUS and later appeared in CHUNITHM NEW in December 2021. Due to licensing agreements tied to the Princess Connect! Re:Dive IP, Lost Princess remains exclusive to Japanese-region maimai cabinets, making it a destination track for players visiting arcades in Japan.
