BPM15Q is a DJ vocal-unit duo consisting of Ichigo Rinahamu (aka Rina Yokoyama) and Nicamoq. Their genre can be described as yume-kawaii (Dreamy-Cute) [夢かわいい], with EDM, future bass, and Trap elements.
The name BPM15Q is pronounced in Japanese as "BPM Ichigokyuu", where "ichi" is "1", "go" is "5" and "kyuu" is "Q".
This is a play on words, as "Ichigokyuu" is a combination of "Ichigo" and "kyuu" from the names "Ichigo Rinahamu" and "Nicamoq" (pronounced "Nikamokyuu" [にかもきゅ]).
They have now disbanded.
