I'm Here (feat. Merry Kirk-Holmes) is the main theme of Sonic Frontiers (2022), the open-world action-adventure entry in Sega's long-running Sonic the Hedgehog franchise. The track was composed by series veteran Tomoya Ohtani, known for his work on Sonic Unleashed, Sonic Colors, and Sonic Forces, and features vocals by Merry Kirk-Holmes, frontman of the metalcore band To Speak of Wolves. Its driving rock instrumentation and anthemic chorus underscore the game's themes of exploration and self-discovery across the Starfall Islands, delivering one of the more emotionally resonant vocal themes in the franchise's modern era. The song was added to maimai DX BUDDiES on November 24, 2023, as a GAME & VARIETY (ゲーム＆バラエティ) category track, marking its first appearance in any rhythm game. Its MASTER chart (level 13.2, designed by はっぴー) contains a widely noted visual easter egg: slide note patterns that trace the letters S-O-N-I-C across the playfield. The EXPERT chart (level 10, designed by サファ太) offers a dense arrangement of 531 notes that captures the song's energetic build-ups. A remixed version titled I'm Here - Revisited, with new vocals by Kellin Quinn of Sleeping with Sirens, was later featured in the Sonic Frontiers expansion The Final Horizon.
