Where the Chocolate Went OST

Does anyone know the name of the song in the quest Where the Chocolate Went? I always fight that Laplace demon and I hear a girl singing but the fight never last long enough for me to hear her sing it fully.

It's Stratos's character song " ザ・ヒーロー・ストライク!! " I think

Are you talking about the music at the being of the video? If so I want that 🎶 🎧 for my room! Another quest!

It seems like the songs in the Laplace fight are different depending on the guest character that shows up (Matoi, Io or Stratos). Presumably they're character songs of some kind, but I must admit I struggle to hear them over the sound of how boring the quest is.

I remember back in 2013 when the song used for "Where's the Chocolate" was Kimi no Tame Nara Shineru, and then for White Day they used Aka Chan wa Doko Kara Kuru no. I do wish they'd bring that back, or at least have the music discs available again for NA/Global.
