Boku wa Kuuki ga Yomenai (僕は空気が嫁ない) is a high-energy Vocaloid track by cosMo＠暴走P (cosMo@Bousou-P), one of the most well-known producers in the Vocaloid doujin scene, featuring GUMI on vocals. The song's title is a deliberate pun: the standard Japanese idiom 空気が読めない (kuuki ga yomenai) means "can't read the room" or "socially oblivious," but the title swaps 読めない (yomenai, "can't read") with the homophonic 嫁ない (yomenai, "can't marry"), rewriting the phrase as "I Can't Marry the Air." The wordplay is characteristic of cosMo＠暴走P's lyrical and stylistic wit. Clocking in at 192 BPM, the track fits the producer's signature fast-paced, synth-driven sound. It was added to maimai DX during the UNiVERSE season on September 16, 2021, under the niconico & Vocaloid category, with DX charts available across all regions. Standard (STANDARD) charts followed later, introduced through the Circle Festa Season 2 event on December 5, 2025, and receiving a general unlock with the CiRCLE PLUS update on March 19, 2026. The song's Master charts, both DX and Standard, sit at level 13 but with different constants and designers, offering two distinct high-difficulty interpretations of the same track.
