This is listed on last.fm as a CHRONOS (クロノス) release, but it's likely the session band Daikon (Wara) (大根(笑)). (That session's lineup mostly comes from Fierce, but its dual vocalists are unknown. Perhaps one of them is from CHRONOS (クロノス), which would explain the discrepancy.) Further evidence for this is that the song Good bye Natsuo (Good bye 夏男) is attributed to Daikon (Wara) (大根(笑)) in an omnibus.
