This is a fascinating two-for-one soundtrack combining Ao no Mamade ("Stay Blue") with Tenku Danzai Skelter Heaven, and if that second title rings a bell, it should -- Skelter Heaven has earned a legendary reputation as one of the worst-rated anime OVAs ever made.

But set the memes aside, because the music tells a different story. The Ao no Mamade portion opens with the achingly hopeful "Surely One Day... In a Far Off Place" and the title track "Stay Blue," both carrying a gentle earnestness typical of mid-2000s visual novel romance.
The character themes form the heart of the Ao no Mamade section, with dedicated pieces for Natsuki, Maina, Chiharu, Kaya, Azusa, and Yuzu each establishing their own musical personality. "Everyday" captures slice-of-life warmth, while "Silence" and "Closed Door" hint at the dramatic turns visual novels inevitably take.
The cafe tracks -- "Deep Blue Forest's Cafe Part 1" and "Part 2" -- suggest a cozy recurring location that probably serves as the game's emotional home base, the kind of place where characters have their most meaningful conversations.
The Skelter Heaven portion pivots hard into sci-fi action territory. "God of Death ~Death Scythes~" and "The Source of Infection" carry a dark urgency that's completely at odds with the gentle romance of the first half, and "SKELTER HEAVEN 2004" serves as the bombastic main theme for the mecha anime side of this package.
"Theme of RIN" closes things out with a character piece from the OVA. The whole release is a time capsule of a very specific era in Japanese media, where visual novels and anime shared soundtracks, budgets, and a charmingly earnest ambition that transcended their production values.
