the All Womans Talk website by Cassandra Rose for being her sixth inclusion on the "7 Ingenious Songs Based on Video Games". A member at Buzznet listed "Passion" and "Sanctuary" on their top playlist, whilst Joy mentioned the tracks in their "An Intro to Japanese Music in 5 Artists". Jenni Lada from Technology Tell recommended "Passion" over "Sanctuary", and also listed it as a "Recommended track" from the singers discography. IGN listed it as number four in their top ten list of RPG title tracks, commenting that the song "lifted the doubts they had about the game's potential". Despite commercial success, "Passion" was not able to match the sales of "Hikari"; "Passion" sold over 112,000 physical units (with an additional 200,000 digital and cellphone units), coming to a total of over 350,000 units. However, the latter track sold over 860,000 units in Japan, making it one of her best selling singles. "Passion" also became her lowest selling single until her 2008 double A-side release "Stay Gold" / "Heart Station". In early 2013, an announcement confirmed the development of the third instalment of the Kingdom Hearts console game. In October that year, Utada's father, Teruzane Utada, was asked on Twitter about their contribution towards the third installment, to which Teruzane replied, "Yes." The reply prompted a large response through social media in Japan and America. However, the following day Teruzane took to Twitter again to clarify that he and Hikaru are "undecided" on contributing towards the song, stating that he was "confused" by the question when he was asked.
